DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

[0031] The invention presents a cooking system 100 for cooking a foodstuff as exemplified in FIG. 1 or 2: the cooking system 100 comprises a cooking device 20 and a package 10, the package comprising a foodstuff material in its inner volume. The package 10 comprises identification means 11 (typically a code) with foodstuff information related to phases of a preparation process for cooking the foodstuff. The encoded information comprises data on at least one foodstuff parameter influencing the preparation of the foodstuff, which considers the deviation of the real value of this at least one parameter with respect to a reference value of it.

[0032] Typically, the cooking device 20 is an oven or a microwave oven which is able to process the foodstuff content of the package 10. In many cases, the foodstuff in the package 10 is a frozen product, which is taken out from the package before it is processed in the device 20: the device then applies a cooking procedure depending on the product to be cooked and further on certain parameters as it will be further explained.

[0033] When the product is being manufactured, there are certain parameters which can deviate from standard production, such as for example the actual weight of the product, or the actual weight of the ingredients in it. When a standard cooking process is applied to this product, final results will deviate from expected, and the product will not be optimal. Therefore, the codification in the identification means 11 of the product needs to take into consideration the real parameters in production. In the production line, at least one parameter (for example, the weight of the product and/or of its ingredients) is measured and it is indicated or printed in the identification means 11. According to the invention, at least one foodstuff parameter influencing the preparation or cooking of the foodstuff is comprised in the identification means 11, this at least one parameter considering the deviation of its real value with respect to a reference value of it. Typically, the at least one parameter measured in the invention is one or a combination of the following: weight of the foodstuff; weight of one or several ingredients in the foodstuff; geometrical distribution of one or several ingredients in the foodstuff; foodstuff initial temperature; foodstuff age; foodstuff uniformity; proportion and/or shape dimension of one or several ingredients in the foodstuff. As it will be further explained in more detail, the device 20 will then apply a certain cooking process optimal for the real foodstuff being cooked so the consumer will be ensured with same guaranteed quality at the end, i.e. the optimal process is stablished taking into consideration the real value of at least one foodstuff parameter influencing the foodstuff preparation process.

[0034] In the package 10 described, the codes further comprise foodstuff information, such as brand and/or foodstuff group and/or foodstuff type. This foodstuff information is used to stablish the reference value of the at least one parameter significantly influencing the preparation of the foodstuff.

[0035] When it comes to using the system of the invention with foodstuff originally frozen when introduced in the device, the identification means can further be provided with at least one dynamic parameter, such as the departing temperature of the product when being introduced in the device. For this, the identification means 11 will be further provided with encoded information made using for example temperature sensitive ink varying depending on real temperature dynamically measured with time, which therefore indicates the device the real temperature of the foodstuff at the moment in time when the product is being cooked. For example, several dots are made with temperature sensitive ink: some of them start disappearing when the temperature raises for example, so the remaining dots indicate the device the real temperature of the foodstuff to cook, so cooking parameters are consequently adapted.

[0036] Preferably, in the package 10 of the invention, the passage from distinct phases in the preparation process for cooking the foodstuff is triggered by the phase duration and/or by the instant foodstuff temperature and/or by the foodstuff moisture content and/or by the foodstuff colour and/or by the foodstuff absorption at specific wavelengths

[0037] The cooking system according to the invention further comprises a control system 16 and a code processing system 18, similar to those described in patent application EP 15165920.8, belonging to the same applicant and incorporated by reference, herewith.

[0038] The control system 16, an example of which is illustrated in FIG. 3, is operable to control the cooking device 20 to prepare the foodstuff. The control system 16 typically comprises: a user interface 36; a processor 38; optional sensors 40; a power supply 42; an optional communication interface 44; all of these having been described in EP 15165920.8.

[0039] Typically, the package 10 comprises an external package and inside a foodstuff which can optionally be frozen. The package 10 may be formed from various materials, such as metal or plastic or a combination thereof. In general, the material is selected such that it is food-safe and can withstand the cooking temperatures. As discussed, the identification means 11 are preferably arranged in the external package and are read by the code processing system 18, which obtains an image of the code on the package 10 and processes said image to decode the encoded foodstuff information from which the preparation information of said foodstuff can be accessed. As shown in FIG. 3, the code processing system 18 comprises an image capturing device 54, an image processing device 56 and an output device 72.

[0040] The distinct phases in the preparation process for cooking the foodstuff may for example comprise values of one or a plurality of the following parameters: [0041] type of cooking or heating means used (microwave, infrared, hot air, etc.) [0042] time of application of each of the cooking or heating means used [0043] frequency of microwave heating means [0044] temperature of hot air heating means [0045] power of infrared heating means [0046] positioning or geometrical application of each of the heating means used [0047] cooling means used [0048] time of application of cooling means [0049] temperature of cooling air used [0050] temperature of the product at the end of the process [0051] phase identifier, e.g. an alphanumeric identifier, to identify which of a plurality of phases the aforesaid one or more parameters relate etc.

[0052] As already mentioned, it has to be taken into consideration that the codes, system and method described in EP 15165920.8 is incorporated herewith by reference, also different embodiments of said code therein described.

[0053] According to another aspect, the invention further relates to a method of cooking a foodstuff using the system 100 previously described. The method according to the invention comprises: [0054] obtaining one or more digital images of a plurality of codes of the container 10; [0055] processing said digital image(s) to decode the foodstuff information; [0056] accessing data to determine processing phases and their order; [0057] a control system operable to control the preparation unit to execute the preparation process using said processing phases and their order.

[0058] According to the invention, the foodstuff cooking system 100 typically comprises a container 10 as the one described and a cooking device 20. The system 100 comprises a code processing system 18 and a control system 16: as shown in FIGS. 9 and 10, there are two possible embodiments: the devoice 20 can comprise both the processing system 18 and the control system 16 or it can only comprise the control system 16, the processing system 18 being in the system 100. In any of the two embodiments, the code processing system 18 is operable to obtain one or more digital image(s) of a plurality of codes of the package 10 and process said digital image(s) to decode for each parameter the encoded foodstuff information. The control system 16 is then operable to control the cooking device 20 according to a preparation process comprising one or a plurality of phases in a determined order, the cooking process being stablished according to the foodstuff parameters information.

[0059] The cooking process can be stablished by the control system 16 referring to a stored library of cooking recipes or it can be stablished by the control system 16 being connected to a remote server in order to access updated foodstuff processing information.

[0060] The code processing system 18 can be arranged in the cooking device 20 (FIG. 8) and/or in the system 100 (FIG. 9) and/or be externally arranged (not shown). FIG. 8 shows the case where both the processing system 18 and the control system 16 are arranged in the cooking device 20, so the communication is made within the device 20. FIG. 9 shows the case where only the processing system i18 is in the device 20 and therefore the communication with the control system 16 is made by Bluetooth or Wi Fi or similar.

[0061] Although the present invention has been described with reference to preferred embodiments thereof, many modifications and alternations may be made by a person having ordinary skill in the art without departing from the scope of this invention which is defined by the appended claims.
