Abstract
Disclosed herein is preservation system for nutritional substances. The preservation system obtains information about the nutritional substance to be preserved, senses and measures the external environment to the preservation system, senses and measures the internal environment to the preservation system, senses and measures the state of the nutritional substance, and stores such information throughout the period of preservation. Using this accumulated information, the preservation system can measure, or estimate, changes in nutritional content (usually degradation) during the period of preservation. Additionally, the preservation system can use this information to dynamically modify the preservation system to minimize detrimental changes to the nutritional content of the nutritional substance, and in some cases actually improve the nutritional substance attributes.

(23) The modules in the systems can be understood to be integrated in some instances and in particular embodiments, only particular modules may be interconnected.
(24)
(25) Module 200 is the creation module. This can be a system, organization, or individual which creates and/or originates nutritional substances. Examples of this module include a farm which grows produce; a ranch which raises beef; an aquaculture farm for growing shrimp; a factory that synthesizes nutritional compounds; a collector of wild truffles; or a deep sea crab trawler.
(26) Preservation module 300 is a preservation system for preserving and protecting the nutritional substances created by creation module 200. Once the nutritional substance has been created, generally, it will need to be packaged in some manner for its transition to other modules in the nutritional substances industry 10. While preservation module 300 is shown in a particular position in the nutritional substance industry 10, following the creation module 200, it should be understood that the preservation module 300 actually can be placed anywhere nutritional substances need to be preserved during their transition from creation to consumption.
(27) Transformation module 400 is a nutritional substance processing system, such as a manufacturer who processes raw materials such as grains into breakfast cereals. Transformation module 400 could also be a ready-to-eat dinner manufacturer who receives the components, or ingredients, also referred to herein as component nutritional substances, for a ready-to-eat dinner from preservation module 300 and prepares them into a frozen dinner. While transformation module 400 is depicted as one module, it will be understood that nutritional substances may be transformed by a number of transformation modules 400 on their path to consumption.
(28) Conditioning module 500 is a consumer preparation system for preparing the nutritional substance immediately before consumption by the consumer. Conditioning module 500 can be a microwave oven, a blender, a toaster, a convection oven, a cook, etc. It can also be systems used by commercial establishments to prepare nutritional substance for consumers such as a restaurant, an espresso maker, pizza oven, and other devices located at businesses which provide nutritional substances to consumers. Such nutritional substances could be for consumption at the business or for the consumer to take out from the business. Conditioning module 500 can also be a combination of any of these devices used to prepare nutritional substances for consumption by consumers.
(29) Consumer module 600 collects information from the living entity which consumes the nutritional substance which has passed through the various modules from creation to consumption. The consumer can be a human being, but could also be an animal, such as pets, zoo animals and livestock, which are they themselves nutritional substances for other consumption chains. Consumers could also be plant life which consumes nutritional substances to grow.
(30) Information module 100 receives and transmits information regarding a nutritional substance between each of the modules in the nutritional substance industry 10 including, the creation module 200, the preservation module 300, the transformation module 400, the conditioning module 500, and the consumer module 600. The nutritional substance information module 100 can be an interconnecting information transmission system which allows the transmission of information between various modules. Information module 100 contains a database, also referred to herein as a dynamic nutritional value database, where the information regarding the nutritional substance resides. Information module 100 can be connected to the other modules by a variety of communication systems, such as paper, computer networks, the internet and telecommunication systems, such as wireless telecommunication systems. In a system capable of receiving and processing real time consumer feedback and updates regarding changes in the nutritional, organoleptic, and/or aesthetic value of nutritional substances, or N, consumers can even play a role in updating a dynamic nutritional value database with observed or measured information about the nutritional substances they have purchased and/or prepared for consumption, so that the information is available and useful to others in the nutritional substance supply system, such as through reports reflecting the consumer input or through modification of N.
(31)
(32) In this example, where nutritional substance A and nutritional substance B are milk, this N information regarding the nutritional substance degradation profile of each milk could be used by the consumer in the selection and/or consumption of the milk. If the consumer has this information at time zero when selecting a milk product for purchase, the consumer could consider when the consumer plans to consume the milk, whether that is on one occasion or multiple occasions. For example, if the consumer planned to consume the milk prior to the point when the curve represented by nutritional substance B crosses the curve represented by nutritional substance A, then the consumer should choose the milk represented by nutritional substance B because it has a higher nutritional value until it crosses the curve represented by nutritional substance A. However, if the consumer expects to consume at least some of the milk at a point in time after the time when the curve represented by nutritional substance B crosses the curve represented by nutritional substance A, then the consumer might choose to select the milk represented by the nutritional substance A, even though milk represented by nutritional substance A has a lower nutritional value than the milk represented by nutritional substance B at an earlier time. This change to a desired nutritional value in a nutritional substance over a change in a condition of the nutritional substance described in
(33) In
(34) Preservation module 300 includes packers and shippers of nutritional substances. The tracking of changes in nutritional, organoleptic, and/or aesthetic values, or a N, during the preservation period within preservation module 300 allows for dynamic expiration dates for nutritional substances. For example, expiration dates for dairy products are currently based generally only on time using assumptions regarding minimal conditions at which dairy products are maintained. This extrapolated expiration date is based on a worst-case scenario for when the product becomes unsafe to consume during the preservation period. In reality, the degradation of dairy products may be significantly less than this worst-case. If preservation module 300 could measure or derive the actual degradation information such as N, an actual expiration date, referred to herein as a dynamic expiration date, can be determined dynamically, and could be significantly later in time than an extrapolated expiration date. This would allow the nutritional substance supply system to dispose of fewer products due to expiration dates. This ability to dynamically generate expiration dates for nutritional substances is of particular significance when nutritional substances contain few or no preservatives. Such products are highly valued throughout nutritional substance supply system 10, including consumers who are willing to pay a premium for nutritional substances with few or no preservatives.
(35) It should be noted that a dynamic expiration date need not be indicated numerically (i.e., as a numerical date) but could be indicated symbolically as by the use of colorssuch as green, yellow and red employed on semaphoresor other designations. In those instances, the dynamic expiration date would not be interpreted literally but, rather, as a dynamically-determined advisory date. In practice a dynamic expiration date will be provided for at least one component of a single or multi-component nutritional substance. For multi-component nutritional substances, the dynamic expiration date could be interpreted as a best date for consumption for particular components.
(36) By law, in many localities, food processors such as those in transformation module 400 are required to provide nutritional substance information regarding their products. Often, this information takes the form of a nutritional table applied to the packaging of the nutritional substance. Currently, the information in this nutritional table is based on averages or minimums for their typical product. Using the nutritional substance information from information module 100 provided by creation module 200, preservation module 300, and/or information from the transformation of the nutritional substance by transformation module 400, the food processor could include a dynamically generated nutritional value table, also referred to herein as a dynamic nutritional value table, for the actual nutritional substance being supplied. The information in such a dynamic nutritional value table could be used by conditioning module 500 in the preparation of the nutritional substance, and/or used by consumption module 600, so as to allow the ultimate consumer the ability to select the most desirable nutritional substance which meets their needs, and/or to track information regarding nutritional substances consumed.
(37) Information about changes in nutritional, organoleptic, and/or aesthetic values of nutritional substances, or N, is particularly useful in the conditioning module 500 of the present invention, as it allows knowing, or estimating, the pre-conditioning state of the nutritional, organoleptic, and/or aesthetic values of the nutritional substance, and allows for estimation of a N associated with proposed conditioning parameters. The conditioning module 500 can therefore create conditioning parameters, such as by modifying existing or baseline conditioning parameters, to deliver desired nutritional, organoleptic, and/or aesthetic values after conditioning. The pre-conditioning state of the nutritional, organoleptic, and/or aesthetic value of a nutritional substance is not tracked or provided to the consumer by existing conditioners, nor is the N expected from a proposed conditioning tracked or provided to the consumer either before or after conditioning. However, using information provided by information module 100 from creation module 200, preservation module 300, transformation module 400, and/or information measured or generated by conditioning module 500, conditioning module 500 could provide the consumer with the actual, and/or estimated change in nutritional, organoleptic, and/or aesthetic values of the nutritional substance, or N. Further, consumer feedback and updates regarding observed or measured changes in the nutritional, organoleptic, and/or aesthetic value of nutritional substances, or N, can play a role in updating a dynamic nutritional value database with information about the nutritional substances consumers have purchased and/or prepared for consumption, so that the information is available and useful to others in the nutritional substance supply system, such as through reports reflecting the consumer input or through modification of N. Such information regarding the change to nutritional, organoleptic and/or aesthetic value of the nutritional substance, or N, could be provided not only to the consumer, but could also be provided to information module 100 for use by creation module 200, preservation module 300, transformation module 400, so as to track, and possibly improve nutritional substances throughout the entire nutritional substance supply system 10.
(38) The information regarding nutritional substances provided by information module 100 to consumption module 600 can replace or complement existing information sources such as recipe books, food databases like www.epicurious.com, and Epicurious apps. Through the use of specific information regarding a nutritional substance from information module 100, consumers can use consumption module 600 to select nutritional substances according to nutritional, organoleptic, and/or aesthetic values. This will further allow consumers to make informed decisions regarding nutritional substance additives, preservatives, genetic modifications, origins, traceability, and other nutritional substance attributes that may also be tracked through the information module 100. This information can be provided by consumption module 600 through personal computers, laptop computers, tablet computers, and/or smartphones. Software running on these devices can include dedicated computer programs, modules within general programs, and/or smartphone apps. An example of such a smartphone app regarding nutritional substances is the iOS ShopNoGMO from the Institute for Responsible Technology. This iPhone app allows consumers access to information regarding non-genetically modified organisms they may select. Additionally, consumption module 600 may provide information for the consumer to operate conditioning module 500 in such a manner as to optimize nutritional, organoleptic, and/or aesthetic values of a nutritional substance and/or component nutritional substances thereof, according to the consumer's needs or preference or according to target values established by the provider of the nutritional substance, such as the transformer, and/or minimize degradation of, preserve, or improve nutritional, organoleptic, and/or aesthetic value of a nutritional substance and/or component nutritional substances thereof.
(39) Through the use of nutritional substance information available from information module 100 nutritional substance supply system 10 can track nutritional, organoleptic, and/or aesthetic value. Using this information, nutritional substances travelling through nutritional substance supply system 10 can be dynamically valued and priced according to nutritional, organoleptic, and/or aesthetic values. For example, nutritional substances with longer dynamic expiration dates (longer shelf life) may be more highly valued than nutritional substances with shorter expiration dates. Additionally, nutritional substances with higher nutritional, organoleptic, and/or aesthetic values may be more highly valued, not just by the consumer, but also by each entity within nutritional substance supply system 10. This is because each entity will want to start with a nutritional substance with higher nutritional, organoleptic, and/or aesthetic value before it performs its function and passes the nutritional substance along to the next entity. Therefore, both the starting nutritional, organoleptic, and/or aesthetic value and the N associated with those values are important factors in determining or estimating an actual, or residual, nutritional, organoleptic, and/or aesthetic value of a nutritional substance, and accordingly are important factors in establishing dynamically valued and priced nutritional substances.
(40) During the period of implementation of the present inventions, there will be nutritional substances being marketed including those benefiting from the tracking of dynamic nutritional information such as N, also referred to herein as information-enabled nutritional substances, and nutritional substances which do not benefit from the tracking of dynamic nutritional information such as N, which are not information enabled and are referred to herein as dumb nutritional substances. Information-enabled nutritional substances would be available in virtual internet marketplaces, as well as traditional marketplaces. Because of information provided by information-enabled nutritional substances, entities within the nutritional substance supply system 10, including consumers, would be able to review and select information-enabled nutritional substances for purchase. It should be expected that, initially, the information-enabled nutritional substances would enjoy a higher market value and price than dumb nutritional substances. However, as information-enabled nutritional substances become more the norm, the cost savings from less waste due to degradation of information-enabled nutritional substances could lead to their price actually becoming less than dumb nutritional substances.
(41) For example, the producer of a ready-to-eat dinner would prefer to use corn of a high nutritional, organoleptic, and/or aesthetic value in the production of its product, the ready-to-eat dinner, so as to produce a premium product of high nutritional, organoleptic, and/or aesthetic value. Depending upon the levels of the nutritional, organoleptic, and/or aesthetic values, the ready-to-eat dinner producer may be able to charge a premium price and/or differentiate its product from that of other producers. When selecting the corn to be used in the ready-to-eat dinner, the producer will seek corn of high nutritional, organoleptic, and/or aesthetic value from preservation module 300 that meets its requirements for nutritional, organoleptic, and/or aesthetic value. The packager/shipper of preservation module 300 would also be able to charge a premium for corn which has high nutritional, organoleptic, and/or aesthetic values. And finally, the packager/shipper of preservation module 300 will select corn of high nutritional, organoleptic, and/or aesthetic value from the grower of creation module 200, who will also be able to charge a premium for corn of high nutritional, organoleptic, and/or aesthetic values.
(42) The change to nutritional, organoleptic, and/or aesthetic value for a nutritional substance, or N, tracked through nutritional substance supply system 10 through nutritional substance information from information module 100 can be preferably determined from measured information. However, some or all such nutritional substance N information may be derived through measurements of environmental conditions of the nutritional substance as it traveled through nutritional substance supply system 10. Additionally, some or all of the nutritional substance N information can be derived from N data of other nutritional substances which have traveled through nutritional substance supply system 10. Nutritional substance N information can also be derived from laboratory experiments performed on other nutritional substances, which may approximate conditions and/or processes to which the actual nutritional substance has been exposed. Further, consumer feedback and updates regarding observed or measured changes in the nutritional, organoleptic, and/or aesthetic value of nutritional substances can play a role in updating N information.
(43) For example, laboratory experiments can be performed on bananas to determine effect on or change in nutritional, organoleptic, and/or aesthetic value, or N, for a variety of environmental conditions bananas may be exposed to during packaging and shipment in preservation module 300. Using this experimental data, tables and/or algorithms could be developed which would predict the level of change of nutritional, organoleptic, and/or aesthetic values, or N, for a particular banana based upon information collected regarding the environmental conditions to which the banana was exposed during its time in preservation module 300. While the ultimate goal for nutritional substance supply system 10 would be the actual measurement of nutritional, organoleptic, and/or aesthetic values to determine N, use of derived nutritional, organoleptic, and/or aesthetic values from experimental data to determine N would allow improved logistics planning because it provides the ability to prospectively estimate changes to nutritional, organoleptic, and/or aesthetic values, or N, and because it allows more accurate tracking of changes to nutritional, organoleptic, and/or aesthetic values, or N, while technology and systems are put in place to allow actual measurement.
(44)
(45) In an alternate embodiment reader 340 can also write to information storage module 330. In this embodiment, information regarding the container and/or nutritional substance 320 can be modified or added to information storage module 330 by the user or shipper.
(46)
(47) When the shipper or user of container 310 desires information from external sensor 360 the shipper or user can use reader 340 to query the controller 350 as to the state of external sensor 360. In the electronic component embodiment, reader 340 could be a user interface device such as a computer which can be electronically connected to controller 350. If the controller-sensor combination is a liquid crystal sensor/display, the ready could be a human looking at the display.
(48) Information in the controller 350 can include creation or origin information from the creation of the nutritional substance 320 and/or prior preservation or transformation information. Information in the controller 350 might additionally include identification information, such as a dynamic information identifier provided on the nutritional substance, which is associated with source and origin information or information regarding prior transformation or prior storage or prior transport of the nutritional substance 320 and other historic information preserved in information module 100. A shipper, or user, of container 310 can operatively connect to controller 350 using reader 340 to retrieve information stored therein, such as the identification information and information from external sensor 360. Information module 100 can connect to controller 350 directly, or using reader 340, to retrieve and preserve information stored therein, such as the identification information and information from external sensor 360, and can further associate that information with the dynamic information identifier provided on the nutritional substance. Alternatively, controller 350 or reader 340 can transmit information stored in controller 350 and collected by controller 350 from external sensor 360 to information module 100 and can further associate the transmitted information with the dynamic information identifier provided on the nutritional substance. A consumer or other member of the nutritional substance supply system would then be able to retrieve from information system 100 the information that was stored and collected by controller 350 by using the dynamic information identifier associated with the nutritional substance and provided on the nutritional substance.
(49) In one embodiment, reader 340 can be directly connected to external sensor 360 to obtain the information from external sensor 360 without need of a controller 350. In another embodiment, external sensor 360 provides information to controller 350 which is presented as a visual display to the shipper or user. Finally, external sensor 360 could provide information directly to the user or shipper by visual means such as a temperature sensitive liquid crystal thermometer.
(50) In an additional embodiment, controller 350 can modify the operation of container 310 so as to modify the preservation capabilities of container 310. For example, if the exterior environment of container 310 would adversely affect the nutritional substance 320, container 310 could adjust the internal environment of container 310 to better preserve the nutritional substance. If nutritional substance needs to be kept within a certain temperature range to preserve its nutritional, organoleptic or aesthetic values or properties, and the external sensor 360 provides exterior temperature information to controller 350, controller 350 could modify container 310 so as to maintain nutritional substance 320 within the required temperature range.
(51) In
(52) In this embodiment, information regarding the external environment sensed by external sensor 360 and provided to controller 350 can be stored in information storage module 330. This storage of external environment can be used to record a history of the external environment container 310 has been subjected to. This would allow the shipper or user of container 310 to understand the external environment the container has been subjected to during the time it has preserved the nutritional substance. Such information can be used to determine if the nutritional substance is no longer safe for consumption or has been degraded such that the nutritional substance is no longer in an optimal state. Additionally, the user of the nutritional substance could modify its transformation, conditioning, or consumption according to any changes that may have occurred because of the external conditions of the container.
(53) Information in the information storage module 330 can include creation or origin information from the creation of the nutritional substance 320 and/or prior preservation or transformation information. Information in information storage module 330 might additionally include identification information, such as a dynamic information identifier provided on the nutritional substance, which is associated with source and origin information or information regarding prior transformation or prior storage or prior transport of the nutritional substance 320 and other historic information preserved in information module 100. A shipper, or user, of container 310 can operatively connect to information storage module 330 through controller 350 using reader 340 to retrieve information stored in storage module 330. Information module 100 can operatively connect to information storage module 330 through controller 350, or using reader 340, to retrieve and preserve information stored in storage module 330, and can further associate that information with the dynamic information identifier provided on the nutritional substance. Alternatively, controller 350 or reader 340 can transmit information stored in information storage module 330 to information module 100 and can further associate the transmitted information with the dynamic information identifier provided on the nutritional substance. A consumer or other member of the nutritional substance supply system would then be able to retrieve from information system 100 the information that was stored in controller 350 by using the dynamic information identifier associated with the nutritional substance and provided on the nutritional substance.
(54) In an additional embodiment, controller 350 can modify the operation of container 310 so as modify the preservation capabilities of container 310. For example, if the exterior environment of container 310 would adversely affect the nutritional substance 320, container 310 could adjust the internal environment of container 310 to better preserve the nutritional substance. Controller 350 can analyze the historic information from external sensor 360, stored in information storage module 330 to determine any long-term exterior conditions environmental If nutritional substance needs to be kept within a certain temperature range to preserve its nutritional, organoleptic or aesthetic values or properties, and the external sensor 360 provides exterior temperature information to controller 350, controller 350 could modify container 310 so as to maintain nutritional substance 320 within the required temperature range.
(55)
(56) In addition to information regarding the environment internal to container 310, information in the internal sensor 370 can include creation or origin information from the creation of the nutritional substance 320 and/or prior preservation or transformation information. Information in the internal sensor 370 might additionally include identification information, such as a dynamic information identifier provided on the nutritional substance, which is associated with source and origin information or information regarding prior transformation or prior storage or prior transport of the nutritional substance 320 and other historic information preserved in information module 100. A shipper, or user, of container 310 can operatively connect to internal sensor 370 using reader 340 to retrieve information stored or collected therein. Information module 100 can connect to internal sensor 370 directly, or using reader 340, to retrieve and preserve information stored or collected therein, and can further associate that information with the dynamic information identifier provided on the nutritional substance. Alternatively, internal sensor 370 or reader 340 can transmit information stored in or collected by internal sensor 370 to information module 100 and can further associate the transmitted information with the dynamic information identifier provided on the nutritional substance. A consumer or other member of the nutritional substance supply system would then be able to retrieve from information system 100 the information that was stored in or collected by internal sensor 370 by using the dynamic information identifier associated with the nutritional substance and provided on the nutritional substance.
(57)
(58) When the shipper or user of container 310 desires information from internal sensor 370 the shipper or user can use reader 340 to query internal sensor 370 through controller 350. In the electronic component embodiment, reader 340 could be a user interface device such as a computer which can be electronically connected to internal sensor 370 through controller 350.
(59) In addition to information regarding the environment internal to container 310, information in the controller 350 can include creation or origin information from the creation of the nutritional substance 320 and/or prior preservation or transformation information. Information in the controller 350 might additionally include identification information, such as a dynamic information identifier provided on the nutritional substance, which is associated with source and origin information or information regarding prior transformation or prior storage or prior transport of the nutritional substance 320 and other historic information preserved in information module 100. A shipper, or user, of container 310 can operatively connect to controller 350 using reader 340 to retrieve information stored therein, such as the identification information and information from internal sensor 370. Information module 100 can connect to controller 350 directly, or using reader 340, to retrieve and preserve information stored therein, such as the identification information and information from internal sensor 370, and can further associate that information with the dynamic information identifier provided on the nutritional substance.

Controller 350 also receives information on the internal environment within container 310 from internal sensor 370 and stores this information in information storage module 330. This information includes the internal temperature, humidity, and certain gas levels within container 310. Finally, nutritional substance sensor 380, which is attached to the surface of the bananas, provides information as to the state of the bananas to controller 350. This information could include surface temperature, surface humidity, gasses being emitted, and surface chemicals. At any time during its shipment and delivery to the distribution warehouse, reader 340 can be used to retrieve both current information and historic information stored within information storage module 330.

EXAMPLES
(92) Nutritional substances are commonly preserved utilizing various freezing techniques. While freezing is well recognized as an effective method of preservation, it can cause a degradation of nutritional, organoleptic, or aesthetic value, a negative N, for the nutritional substance being frozen. Additional N can occur during subsequent storage and transfer of the nutritional substance on its path from being packaged and frozen to being consumed. These additional Ns can occur as a result of: frozen storage; transfer to a distributor or retailer; and storage by the distributor or retailer.
(93)
(94) Some examples will now be provided of how a preservation system for nutritional substances according to the present invention provides beneficial: source and origin information for the nutritional substance; information regarding a change in nutritional, organoleptic, or aesthetic value of the nutritional substance; and information as to a current nutritional, organoleptic, or aesthetic state of the nutritional substance.
(95) In one example, the raw material is freshly caught farm raised salmon. Referring to
(96) The cleaned and cut salmon steaks are then packaged and frozen. Based on the type of packaging used and the freezing process applied, there will be changes, likely a degradation, in nutritional, organoleptic, or aesthetic value. These changes are shown as N.sub.2 in
(97) The packaged and frozen salmon steaks are then put into frozen storage. Based on the type of packaging used and the time and conditions of frozen storage, there will be changes, likely a degradation, in nutritional, organoleptic, or aesthetic value. These changes are shown as N.sub.3 in
(98) The packaged and frozen salmon steaks are eventually transferred to a distributor or retailer. Based on the time and conditions during transfer, there will be changes, likely a degradation, in nutritional, organoleptic, or aesthetic value. These changes are shown as N.sub.4 in
(99) The packaged and frozen salmon steaks are then stored by the distributor or retailer, awaiting sale to a consumer. Based on the time and conditions of storage by the distributor or retailer, there will be changes, likely a degradation, in nutritional, organoleptic, or aesthetic value. These changes are shown as N.sub.5 in
(100) For traditional methods of freezing, it is well understood that the quality of frozen nutritional substances is highly dependent on the rate at which it is frozen. Generally, rapid freezing results in higher quality frozen nutritional substances as compared to slow freezing. When freezing is rapid, there are more locations within the nutritional substance where nucleation occurs, that is, where ice crystallization begins. In contrast, when freezing is slow, there are relatively few nucleation sites resulting in larger ice crystals. It is known that these larger ice crystals can cause mechanical damage to cell walls and can further result in cell dehydration.
(101) Examples of common traditional methods used for freezing nutritional substances include air-blast freezers, plate freezers, and liquid nitrogen freezers. These methods of freezing nutritional substances provide various benefits and advantages depending on the nutritional substance being frozen and upon other factors such as production rate, flexibility, equipment cost, and cost to operate. These methods of freezing nutritional substances can further be differentiated by the respective rates of freezing that they can deliver, which as previously discussed, can have a significant impact on the quality of the nutritional substance.
(102) Air-blast freezers are among the oldest and most commonly used types of freezing equipment. They offer good temperature stability and versatility for many types of products. Air is generally used as the freezing medium and can be still air or forced air. The basic process involves placing nutritional substances in freezing rooms called sharp freezers. Still air freezers are the most economical method of freezing and provide the added advantage of a constant temperature during frozen storage. However, still air freezers are the slowest method of freezing due to the low surface heat transfer coefficient of circulating air inside the room.
(103) Contact freezing can be a more efficient method of freezing in terms of heat transfer mechanism. The most common type of contact freezer is the plate freezer. In this case, the product is pressed between hallow metal plates, either horizontally or vertically, with a refrigerant circulating inside the plates. Pressure is applied for good contact. This type of freezing system is only limited to regular-shaped materials like patties or block-shaped packaged products, and is considerably faster than air-blast freezing in these situations.
(104) Liquid nitrogen freezing, also known as flash freezing, is still more rapid than contact freezing methods such as with plate freezers. The refrigerant is liquid Nitrogen, with a boiling temperature of 196 C. at atmospheric pressure, and is sprayed into the freezer, evaporating upon leaving the spray nozzles and upon contact with the nutritional substance. These systems can provide high heat transfer efficiency, but consume Nitrogen in the range of 1.2-kg Nitrogen per 1-kg of nutritional substance. Typical nutritional substances frozen in this type of system include fish fillets.
(105) A non-traditional freezing system that shows great promise for nutritional substances is known as a Cells Alive System, or CAS, developed by ABI. The technology does not depend on rapid rates of freezing to minimize damage caused by ice crystals, yet can deliver results even better than rapid freezing such as liquid Nitrogen freezing, that is with little to no degradation of nutritional, organoleptic, or aesthetic value. CAS technology uses an oscillating electrical field to cause water molecules within the nutritional substance to spin, stopping them from clustering and forming ice crystals that damage cell walls. Additionally, the spinning motion of the water molecules artificially lowers the freezing point of the water within the nutritional substance to approximately 7 C. Once the nutritional substance reaches this temperature, the oscillating electrical field is turned off and the water freezes almost instantaneously from the inside out, causing minimal or no cell damage. The natural life form of the cells of a CAS frozen nutritional substance is retained, without the physical damage to the cell wall and nucleus that results from ice crystal growth during traditional outside-to-inside freezing methods.
(106) While CAS freezing has found selective application for preserving nutritional substances, the focus has been on organoleptic and aesthetic characteristics such as taste, texture, and appearance. The present invention can not only track, preserve, and communicate the values associated with these characteristics and changes in the values associated with these characteristics, it can additionally track, preserve, and communicate the nutritional value and changes in the nutritional value of a nutritional substance. This will be of great value to a consumer, who can now see the nutritional benefit associated with nutritional substances frozen by CAS methods. It will also be of great value to those offering nutritional substances frozen by CAS methods, as tracking and communicating a degradation in nutritional value close to, or equal to, zero will demonstrate that the nutritional substance offers similar or equal nutritional value as compared to freshly caught, freshly slaughtered, or freshly harvested nutritional substances.
(107) Referring to
(108) For the purpose of the following example it is understood that the amount of degradation to be expected from air-blast freezing is greater than the amount of degradation to be expected from contact freezing which is greater than the amount of degradation to be expected from liquid Nitrogen freezing which is greater than the amount of degradation to be expected from CAS freezing. Because degradation is represented by a negative number, the relationship can be described as: N.sub.2 air-blast freezing<N.sub.2 contact freezing<N.sub.2 liquid Nitrogen freezing<N.sub.2 CAS freezing0. With this context, an example is offered of a preservation system according to the present invention. In this example, a transformer of the salmon steaks provides four varieties of frozen salmon steaks based upon nutritional, organoleptic, or aesthetic values of the product. The products are marketed as: economy; standard; premium; and ultra-premium.
(109) The economy salmon steaks have been packaged and frozen by air-blast freezing, which is known to cause significant degradation, but is economical for the transformer. The standard salmon steaks have been packaged and frozen by contact freezing, such as in a plate freezer, which is known to cause degradation, but less than air-blast freezing. The premium salmon steaks have been packaged and frozen by liquid Nitrogen freezing, also known as flash freezing, which is known to cause less degradation than contact freezing. The ultra-premium salmon steaks have been packaged and frozen by CAS freezing, which is known to cause little to no degradation, which is less than liquid Nitrogen freezing.
(110) The transformer stores its economy and standard products at 18 C., and stores its premium and ultra-premium products at 35 C. It is known that degradation of nutritional, organoleptic, or aesthetic value during frozen storage will be greater at storage temperatures of 18 C. compared to degradation of nutritional, organoleptic, or aesthetic value during frozen storage at 35 C. Because degradation is represented by a negative number, the relationship can be described as: N.sub.3 frozen storage at 18 C.<N.sub.3 frozen storage at 35 C.
(111) Further, the transformer transfers its economy and standard products to distributors and retailers at 18 C., and transfers its premium and ultra-premium products to distributors and retailers at 35 C. Because degradation is represented by a negative number, the relationship can be described as: N.sub.4 transfer at 18 C.<N.sub.4 transfer at 35 C.
(112) Still further, the transformer requires its distributors or retailers to store the economy, standard, and premium products at 18 C., but requires its distributors or retailers to store the ultra-premium product at 35 C. Because degradation is represented by a negative number, the relationship can be described as: N.sub.5 storage at 18 C.<N.sub.4 storage at 35 C.
(113) The nutritional, organoleptic, or aesthetic value of any of these four salmon steak products from the transformer can be expressed as the sum of its baseline nutritional, organoleptic, or aesthetic value after each step it goes through on its journey through the nutritional substance supply system. After transformation, the nutritional, organoleptic, or aesthetic value of the economy salmon steak=the nutritional, organoleptic, or aesthetic value of the standard salmon steak=the nutritional, organoleptic, or aesthetic value of the premium salmon steak=the nutritional, organoleptic, or aesthetic value of the ultra-premium salmon steak=N.sub.BASELINE+N.sub.1.

(118) The consumer, or any other constituent in the nutritional substance supply system, can utilize reference information provided on the nutritional substance package by the transformer in the form of a dynamic information identifier. The dynamic information identifier allows retrieval of source and origin information as well as information regarding changes in nutritional, organoleptic, or aesthetic values of the nutritional substance from a nutritional substance information system, such as from a dynamic nutritional value database.
(119) An example of how this benefits a distributor or retailer of the premium salmon steaks, as compared to products provided without a dynamic information identifier will now be discussed. Upon receiving the premium salmon steaks from transfer, the distributor or retailer can verify source and origin information regarding the premium salmon steaks using the dynamic information identifier provided with the nutritional substance to retrieve the source and origin information from a nutritional substance information system. Further, the distributor or retailer can verify that the nutritional, organoleptic, or aesthetic values expected of this type of product have actually been maintained using the dynamic information identifier provided with the nutritional substance to retrieve information regarding actual N associated with the premium salmon steaks from a nutritional substance information system. In this way, the distributor or retailer has access to information regarding N and a current state of nutritional, organoleptic, or aesthetic value of the premium salmon steaks. The nutritional substance information system can communicate the N at transfer to distributor, which would equal N.sub.1+N.sub.2 liquid Nitrogen freezing+N.sub.3 frozen storage at 35 C.+N.sub.4 transfer at 35 C. The nutritional substance information system can further communicate a current nutritional, organoleptic, or aesthetic value of the premium salmon steaks at transfer to distributor, which would equal N.sub.BASELINE+N.sub.2 liquid Nitrogen freezing+N.sub.3 frozen storage at 35 C.+N.sub.4 transfer at 35 C. If the product had been received without a dynamic information identifier, the distributor or retailer would have access to very limited information regarding the product, and no information regarding N or the current state of nutritional, organoleptic, or aesthetic value of the product.
(120) An example of how this benefits a consumer shopping for premium or ultra-premium salmon steaks provided with a dynamic information identifier, as compared to products provided without a dynamic information identifier, will now be discussed. At the supermarket the consumer can verify source and origin information regarding the premium salmon steaks using the dynamic information identifier provided with the nutritional substance to retrieve the source and origin information from a nutritional substance information system. Preferably, this is accomplished with the consumer's smart phone. Further, the consumer can verify that the nutritional, organoleptic, or aesthetic values expected of this type of product have actually been maintained using the dynamic information identifier provided with the nutritional substance to retrieve information regarding actual N associated with the premium salmon steaks from a nutritional substance information system. In this way, the consumer has access to information regarding N and a current state of nutritional, organoleptic, or aesthetic value of the premium salmon steaks. The nutritional substance information system can communicate the current N at the time of the consumer's query, which would equal N.sub.1+N.sub.2 liquid Nitrogen freezing+N.sub.3 frozen storage at 35 C.+N.sub.4 transfer at 35 C.+N.sub.5 storage at 18 C. The nutritional substance information system can further communicate a current nutritional, organoleptic, or aesthetic value of the premium salmon steaks at the time of the consumer's query, which would equal N.sub.BASELINE+N.sub.2 liquid Nitrogen freezing+N.sub.3 frozen storage at 35 C.+N.sub.4 transfer at 35 C.+N.sub.5 storage at 18 C. Now the consumer can verify source and origin information regarding the ultra-premium salmon steaks using the dynamic information identifier provided with the nutritional substance to retrieve the source and origin information from a nutritional substance information system. Preferably, this is accomplished with the consumer's smart phone. Further, the consumer can verify that the nutritional, organoleptic, or aesthetic values expected of this type of product have actually been maintained using the dynamic information identifier provided with the nutritional substance to retrieve information regarding actual N associated with the ultra-premium salmon steaks from a nutritional substance information system. In this way, the consumer has access to information regarding N and a current state of nutritional, organoleptic, or aesthetic value of the ultra-premium salmon steaks. The nutritional substance information system can communicate the current N at the time of the consumer's query, which would equal N.sub.1+N.sub.2 CAS freezing+N.sub.3 frozen storage at 35 C.+N.sub.4 transfer at 35 C.+N.sub.5 storage at 35 C. The nutritional substance information system can further communicate a current nutritional, organoleptic, or aesthetic value of the ultra-premium salmon steaks at the time of the consumer's query, which would equal N.sub.BASELINE+N.sub.1+N.sub.2 CAS freezing+N.sub.3 frozen storage at 35 C.+N.sub.4 transfer at 35 C.+N.sub.5 storage at 35 C. If the product had been offered for sale without a dynamic information identifier, the consumer would have access to very limited information regarding the product, and no information regarding N or the current state of nutritional, organoleptic, or aesthetic value of the product. Because these products were provided with dynamic information identifiers, the consumer can now make an informed comparison of the two products and an informed purchasing decision.
(121) An example of how this benefits a value oriented consumer shopping for economy or standard salmon steaks, as compared to products provided without a dynamic information identifier, will now be discussed. At the supermarket the consumer can verify source and origin information regarding the economy salmon steaks using the dynamic information identifier provided with the nutritional substance to retrieve the source and origin information from a nutritional substance information system.
