A method for ecological utilization of silver carp, including the pretreatment of silver carp and the process of making canned fish surimi. The fish meat of silver carp is processed canned surimi. The fish heads and bones are heated and undergo enzymatic hydrolysis by enzymes, and the residues of the filtration are prepared for fish bone powder. A filtration membrane is used to reduce the volume of the filtrate to 50% of fish surimi and then the filtrate is frozen to ice. The frozen part can be added to fish surimi. The transparent part from membrane filtration was used to produce protein powder or ingredients for beverages. Fish offal can be used to produce protein liquid fertilizer. Fish scales and skins can be used to produce collagen. The method adopts ecological utilization, which makes the silver carp meat used effectively, including its processed wastes. The method is a closed cycle process such that that no pollutants or wastes are discharged during the process.

A revolutionized tuna process according to this invention generally comprising the steps of thawing of frozen tuna, de-heading and degutting, fileting, de-skinning, cleaning of the de-skinned tuna filet, pre-cooking, cooling, packing of the cleaned and pre-cooked tuna loin, and sterilizing the packed tuna loin or freezing the tuna loin. Not only does the process according to this invention reduces the energy utilization by half, it also significantly reduces the time required for cooking and cooling. Therefore, the whole processing time is significantly reduced from at least 8.0 hours in the conventional process to less than 30 minutes.

Provided is a method for preserving raw meat, whereby the raw meat can be preserved in a state where meat juice, savory taste, and moisture are retained in the meat itself, while being moderately sterilized. By heating vacuum-packaged raw meat at a temperature higher than 60 degrees Celsius and not higher than 65 degrees Celsius so as to surely avoid reaching a coagulation temperature of protein; further heating the raw meat for 1 hour to 1 hour and 15 minutes at a temperature condition of higher than 60 degrees Celsius and not higher than 65 degrees Celsius after the core temperature of the meat has exceeded 60 degrees Celsius; and, after the further heating has been completed, rapidly cooling the meat so that the meat does not freeze, and lowering the core temperature of the meat to 4 degrees Celsius or less, the raw meat can be preserved in a state in which meat juice, savory taste, and moisture are retained in the meat itself, while being moderately sterilized, and the preserved meat can be used as an alternative to raw meat.

The invention relates to a method for enhancing the product quality and product safety of meat or foodstuffs of animal or vegetable origin by means of selective pressure and temperature treatment. According to the invention, fresh or warm meat of any form is packed in portions using a film container which has recoil abilities and therefore any liquid possibly escaping from the packed product distributes itself uniformly over the surface of the product. The packed portions are then placed in a container-like treatment device which has, mounted on the surfaces coming into contact with the product, a plurality of cushions, tubes or similarly elastic structures to which a pressure and temperature control medium may be applied. The cushions, tubes or similarly elastic structures are filled with the pressure and temperature control medium in such a manner that substantially uniform pressure forces act on the packed product and the packed product can be held in a predefined temperature range which is maintained for a predetermined period. On expiry of the predetermined period, the packed product is then rapidly cooled by exchanging the temperature control medium.

A system and method are disclosed for processing packaged seafood containing shrimp or other non-crab shellfish species. Embodiments of the disclosed method provide a pasteurized shellfish product having a longer refrigerated shelf-life than experienced with conventional shellfish processing methods, and the shellfish product produced retains more of its original sensory qualities, such as texture, flavor and odor, than are retained by shellfish made according to current processing methods.

The present disclosure provides methods for manufacturing a shelf-stable food product. In a general embodiment, the methods include acoustically mixing the food product with an acoustic mixing device during thermal processing of the food product. The methods of the present disclosure provide several advantages including, but not limited to, rapid achievement of a uniform temperature distribution during thermal processing, retention of nutrient content and organoleptic properties of the food product, and retention of particle integrity in the food product during and after mixing.

A digital pressure canner and related methods of operation that provide for improved safety and consistency during a food canning process by reducing temperature over and undershoot. The digital pressure canner includes a digital control operating with inputs from digital sensors to accurately control the canning temperature during the canning process. By reducing over and undershoot of canning temperatures, foods within the pressure canner are maintained at temperatures sufficient to kill any bacteria or microorganisms for the entire canning cycle. In order to verify operation of the digital canner at sufficient canning temperatures, mechanical safety devices, for example, a pressure relief valve can be utilized in conjunction with digital controllers and sensors to provide audible and visual feedback to a user during the canning process.

There is provided a method of cooking and sterilization of food arranged in a sealed package comprising a one-way valve that opens at a supra-atmospheric pressure of 20-200 mbar, said method comprising the steps of: a) heating the sealed package to cook the food; b) subjecting the sealed package from step a) to a sub-atmospheric pressure such that gas leaves the sealed package through the valve; and c) autoclaving the sealed package from step b) at a supra-atmospheric pressure.

A method for preparing seafood product for significantly extended shelf life is disclosed. The method includes storing extracted and cooked seafood meat in a glass jar leaving a nominal air gap with a screw on cover, where the cover includes a flexible liner to conform to the rim of the glass jar, thereby creating a seal. After the jar is sealed, the jar undergoes a pasteurization process, causing an unsealing and allowing for release of oxygen and microorganisms. Testing has shown a shelf life of at least 43 months with testing on-going.
