DETAILED DESCRIPTION OF THE INVENTION

[0009] (Findings that formed the basis of this disclosure) In recent years, food waste has become a social issue. Food waste refers to food that is discarded without being consumed at each stage of production, distribution, and consumption. This wastes resources such as water, land, and energy needed for food production, and also affects greenhouse gas emissions.

[0010] In particular, the inventors focused on the problem of food waste at the consumption stage.

[0011] The information provision method according to the background art disclosed in Patent Document 1 provides different recipes depending on the state of deterioration of food. For example, if the tomatoes are not deteriorated, a recipe for tomato salad is provided, and if the tomatoes are deteriorated, a recipe for tomato sauce is provided.

[0012] Patent Document 1 simply provides different recipes depending on the state of deterioration of the food. However, the present inventors thought that at the consumption stage, it is necessary to both prevent food waste and ensure nutritional management for the consumer who consumes the food.

[0013] In other words, taking into consideration the nutritional management of consumers, it is important to propose to users who will be consuming the food an optimal recipe that is suited to the nutritional status, including the amount of nutrients remaining in the food.

[0014] In order to solve this problem, the inventor discovered that by calculating the nutrient status based on the degree of deterioration of food and generating consumption information including suggestions on how to consume the food based on the nutrient status, it is possible to suggest optimal recipes to users based on the nutrient status, and this led to the present disclosure.

[0015] Next, each aspect of the present disclosure will be described.

[0045] (Embodiments of the present disclosure) Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Elements with the same reference numerals in different drawings indicate the same or corresponding elements. Furthermore, the components, the layout positions of the components, the connection forms, the order of operations, etc. shown in the following embodiments are merely examples and are not intended to limit the present disclosure. The present disclosure is limited only by the claims. Therefore, among the components in the following embodiments, components that are not described in the independent claims that represent the highest concept of the present disclosure are not necessarily required to achieve the objectives of the present disclosure, but are described as constituting more preferred forms.

[0046] 1 is a diagram showing a simplified configuration of a recipe providing system according to an embodiment of the present disclosure. The recipe providing system provides users with consumption information on food items that are subject to management. The food items include ingredients. The consumption information includes recipes.

[0047] 1, the recipe providing system includes an information processing device 1, a user terminal 2, a first management device 31, a second management device 32, and a third management device 33. The information processing device 1 can communicate with the user terminal 2, the first management device 31, the second management device 32, and the third management device 33 via a communication network 4. The communication network 4 is any communication network that uses a dedicated line or a public line.

[0048] In the example of this embodiment, the information processing device 1 is a cloud server. However, the information processing device 1 may also be an on-premise server, an edge server, or a dedicated terminal installed in a user's home. Furthermore, the functions of the information processing device 1 may be implemented in the user terminal 2 by realising the functions of the information processing device 1 as part of the functions of the user terminal 2. Furthermore, the functions of the information processing device 1 may also be implemented in a cooking appliance 5, which will be described later.

[0049] 1, the information processing device 1 includes a processing unit (information processing unit) 11, a storage unit 12, and a communication unit 13. The processing unit 11 includes a processor such as a CPU. The storage unit 12 includes an HDD, an SSD, a semiconductor memory, or the like. The communication unit 13 includes a communication module compatible with the communication standard of the communication network 4.

[0050] In this embodiment, the user terminal 2 is a smartphone owned by the user. However, the user terminal 2 may also be a mobile phone, a tablet terminal, a personal computer, or a dedicated terminal installed in the user's home.

[0051] As shown in FIG. 1, the user terminal 2 includes a processing unit 21, a memory unit 22, a communication unit 23, an input unit 24, a display unit 25, and an imaging unit 26. The processing unit 21 includes a processor such as a CPU. The memory unit 22 includes a HDD, an SSD, a semiconductor memory, or the like. The communication unit 23 includes a communication module compatible with the communication standard of the communication network 4. The input unit 24 includes an input device such as a mouse, a keyboard, a touch panel, or a two-dimensional code reader. The display unit 25 includes a liquid crystal display, an organic EL display, or the like. The imaging unit 26 includes an optical system, a CMOS image sensor, or the like.

[0052] The first management device 31 manages a database 51 described later that shows the correspondence between the state information indicating the state of the food to be managed and the degree of deterioration of the food. The state of the food includes the external state of the food, and the acquisition of the state information includes the acquisition of image information obtained by imaging the external appearance of the food. The state of the food may further include the distribution state of the food, and the acquisition of the state information may further include the acquisition of product information of the food including the distribution state. The distribution state may include at least one of the production place, production date and time, storage method, and transportation method of the food. The production place includes the harvesting place, processing place, shipping place, etc. The production date and time includes the harvesting date and time, processing date and time, shipping date and time, etc. The storage method includes refrigerated storage, frozen storage, room temperature storage, etc. The transportation method includes land transportation or air transportation, etc. The degree of deterioration of the food includes numerical values such as the moisture content, oxidation degree, or odor value of the food.

[0053] Figure 2 is a diagram showing a simplified example of the database 51. The database 51 shows the correspondence between the image of the external appearance of the food and the degree of deterioration of the food. For example, an image of fresh fish is associated with a degree of deterioration including a moisture content X1, an oxidation degree Y1, and an odor value Z1. Also, an image of slightly discolored fish is associated with a degree of deterioration including a moisture content X2 (<X1), an oxidation degree Y2 (>Y1), and an odor value Z2 (>Z1). Further, an image of severely discolored fish is associated with a degree of deterioration including a moisture content X3 (<X2), an oxidation degree Y3 (>Y2), and an odor value Z3 (>Z2). For various foods to be managed, the moisture content X, oxidation degree Y, and odor value Z of the food are measured by an operator using existing measuring instruments such as a moisture content sensor, an oxidation degree sensor, or an odor sensor. Also, when measuring using these measuring instruments, an image of the external appearance of the food is captured by the operator. The first management device 31 associates the acquired image of the food with the measured value of the measuring instrument and registers it in the database 51.

[0054] The second management device 32 manages a database 52 (described below) that indicates the correspondence between the degree of deterioration of the food to be managed and the nutrient status of the food. The nutrient status of a food includes the numerical value of the amount of nutrients remaining in the food. Nutrients include proteins, lipids, carbohydrates, vitamins, minerals, etc. If a food contains multiple nutrients, the nutrient status of the food may include the amount of each of the multiple nutrients. Furthermore, if a food contains multiple nutrients, the nutrient status of the food may further include the content ratio of the multiple nutrients in the food.

[0055] FIG. 3 is a simplified diagram showing an example of database 52. Database 52 shows the correspondence between the deterioration level of a food product, the nutrient status of the food product, and an evaluation value calculated from the nutrient status. For example, a deterioration level including a moisture content X1, an oxidation level Y1, and an odor value Z1 is associated with a nutrient status including the amount of each nutrient (protein A1, lipid B1, carbohydrate C1, vitamin D1, and mineral E1) and an evaluation value K1. A deterioration level including a moisture content X2, an oxidation level Y2, and an odor value Z2 is associated with a nutrient status including the amount of each nutrient (protein A2, lipid B2, carbohydrate C2, vitamin D2, and mineral E2) and an evaluation value K2. A deterioration level including a moisture content X3, an oxidation level Y3, and an odor value Z3 is associated with a nutrient status including the amount of each nutrient (protein A3, lipid B3, carbohydrate C3, vitamin D3, and mineral E3) and an evaluation value K3. For various foods to be managed, the amount of each nutrient (protein A, lipid B, carbohydrate C, vitamin D, mineral E) is measured by known component analysis or the like. Furthermore, an evaluation value K is calculated based on the nutrient status, including the amount of each nutrient. The evaluation value K may be a value indicating the ratio of the current nutrient status after deterioration to the nutrient status in the initial, non-deteriorated state. The second management device 32 associates the acquired degree of deterioration, nutrient status, and evaluation value of the food, and registers them in the database 52.

[0056] The third control device 33 manages recipe information for dishes using the foods that are the subject of management. The recipe information is an example of a suggested method for consuming a food. The recipe information may include information indicating the type of dish using one or more foods. The recipe information may also include information indicating the cooking method for one or more foods. The third control device 33 may also perform processes such as adding, deleting, or changing the recipe information by obtaining feedback information from the user terminal 2 via the communication network 4.

[0057] 4 is a diagram showing information stored in the storage unit 12 of the information processing device 1. The storage unit 12 stores first relationship information 61, second relationship information 62, and a program 63. The storage unit 12 includes a computer-readable nonvolatile storage medium, and the program 63 is stored in the storage medium.

[0058] The first relationship information 61 defines the relationship between the state of the food to be managed and the degree of deterioration. The first relationship information 61 may be a mathematical formula, table information such as an LUT, or an estimation model generated using artificial intelligence (hereinafter referred to as an "AI model"). When the first relationship information 61 is an AI model, for example, an AI model that estimates the degree of deterioration based on an image of the food is generated by machine learning using the database 51 shown in FIG. 2 as learning data. The generation of the AI ​​model by machine learning may be executed by the information processing device 1, the first management device 31, or, if there are sufficient computing resources, the user terminal 2.

[0059] The second relationship information 62 defines the relationship between the degree of deterioration and the nutrient status of the food to be managed. The second relationship information 62 may be a mathematical formula, table information such as an LUT, or an AI model. When the second relationship information 62 is an AI model, for example, an AI model that estimates the nutrient status based on the degree of deterioration of the food is generated by machine learning using the database 52 shown in FIG. 3 as training data. The generation of the AI ​​model by machine learning may be executed by the information processing device 1, the second management device 32, or, if there are sufficient computing resources, the user terminal 2.

[0060] 5 is a simplified diagram showing the functional configuration of the processing unit 11 of the information processing device 1. As functions realized by the processor executing the program 63 read from the storage unit 12, the processing unit 11 has an acquisition unit 71, a first calculation unit 72, a second calculation unit 73, a generation unit 74, and an output unit 75. Details of the processing content executed by each processing unit will be described later.

[0061] 6 to 8 are flowcharts showing the processing contents executed by the processing unit 11 of the information processing device 1.

[0062] 6, first, in step SP01, acquisition unit 71 acquires status information indicating the status of the food to be managed. As described above, the status information includes image information and product information.

[0063] Specifically, referring to FIG. 7, first, in step SP11, the acquisition unit 71 acquires image information of an image of the appearance of food. The image information may be image information of food captured using the imaging unit 26 of the user terminal 2. Furthermore, if an imaging unit is built into a refrigerator installed in the user's home, the image information may be image information of food captured using the imaging unit. Furthermore, if an imaging unit is installed on a display shelf, ceiling, shopping cart, or the like in a store selling food, the image information may be image information of food captured using the imaging unit. The image information may include time information indicating the date and time the image was captured.

[0064] Next, in step SP12, the acquisition unit 71 acquires product information for the food. As described above, the product information includes the distribution status, which includes at least one of the food's production location, production date and time, storage method, and transportation method. The product information is stored in a two-dimensional code or the like printed on the food's packaging or the like. The product information may be information read from the two-dimensional code using a two-dimensional code reader included in the input unit 24 of the user terminal 2. Alternatively, the product information may be information manually entered by the user using a touch panel or keyboard included in the input unit 24 of the user terminal 2. Alternatively, if the food is purchased through a mail-order service using the Internet or the like, the product information may be information acquired from mail-order purchase record information or the like. Note that if the two-dimensional code or purchase record information or the like contains information identifying the food's retailer, the information may be centrally managed for each retailer.

[0065] 6, next in step SP02, first calculation unit 72 calculates the degree of deterioration of the food based on the status information acquired in step SP01. First calculation unit 72 calculates the degree of deterioration of the food based on the status information acquired in step SP01 and first relationship information 61 acquired by reading it from memory unit 12.

[0066] The first calculator 72 may set the resolution for calculating the deterioration level according to the resolution of the image included in the status information acquired in step SP01. For example, the higher the image resolution, the finer the resolution may be set, and the lower the image resolution, the coarser the resolution may be set.

[0067] In addition, if there is a time difference between the current time, which is the timing for determining the degree of deterioration, and a future time, which is the timing for the next cooking, the first calculation unit 72 may calculate the degree of deterioration at the future time based on multiple time series data of the degree of deterioration and the time difference.

[0068] Furthermore, if the condition information acquired in step SP01 includes product information, the first calculation unit 72 may correct the deterioration level calculated based on the image information based on the product information. As described above, the product information includes the distribution status, which includes the food's production location, production date and time, storage method, and transportation method. The first calculation unit 72 corrects the deterioration level using a correction coefficient set according to the magnitude of the influence of the food's distribution status on food deterioration, taking into account the influence. Note that instead of correcting the deterioration level calculated based on the image information based on the product information, the information processing device 1 may create the first relationship information 61 based on the image information and the product information. If the first relationship information 61 is an AI model, an AI model that estimates the deterioration level based on the image information and the product information is generated by machine learning using the food's image information, product information, and deterioration level as learning data.

[0069] Next, in step SP03, second calculation unit 73 calculates the nutrient status of the food based on the deterioration level calculated in step SP02. Second calculation unit 73 calculates the nutrient status of the food based on the deterioration level calculated in step SP02 and second relationship information 62 obtained by reading it from storage unit 12. Second calculation unit 73 also calculates evaluation value K based on the calculated nutrient status.

[0070] Next, in step SP04, the generation unit 74 generates consumption information including suggestions on how to consume food based on the nutrient status calculated in step SP03.

[0071] Specifically, referring to FIG. 8, first, in step SP21, the generation unit 74 determines whether or not the evaluation value K calculated in step SP03 exceeds the first threshold value H1.

[0072] If the evaluation value K is greater than the first threshold value H1 (step SP21: YES), then in step SP22, the generation unit 74 generates consumption information 81 including suggestions on how to preserve food.

[0073] 9A is a diagram showing an example of consumption information 81. Consumption information 81 includes a text message suggesting how to store food, saying, "There is plenty of nutrients left. Please store in the refrigerator."

[0074] If the evaluation value K is equal to or less than the first threshold value H1 (step SP21: NO), then in step SP23 the generation unit 74 determines whether the evaluation value K calculated in step SP03 exceeds a second threshold value H2. The second threshold value H2 is set to a value smaller than the first threshold value H1.

[0075] If the evaluation value K is greater than the second threshold value H2 (step SP23: YES), then in step SP24, the generation unit 74 generates consumption information 82, 83 including suggestions on how to consume the food.

[0076] 9B is a diagram showing an example of consumption information 82. Consumption information 82 includes a text message suggesting how to consume food, including the expiration date, saying, "Nutrient content is decreasing. Please consume by tomorrow."

[0077] FIG. 9C is a diagram showing an example of consumption information 83. The consumption information 83 includes a text message suggesting how to consume the food, including cooking methods, such as "The vitamin content of the potatoes has decreased. We recommend cooking them with carrots, which still have plenty of vitamins." The consumption information 83 also includes a list of recommended dishes 91 that include types of dishes using the food, such as curry rice, stew, and pot-au-feu. The consumption information 83 may also include a checkbox 92 that the user taps to select a dish from the list of recommended dishes 91, and an icon 93 that the user taps to view the recipe for the selected dish.

[0078] If the evaluation value K is equal to or less than the second threshold value H2 (step SP23: NO), then in step SP25, the generation unit 74 generates consumption information 84 that includes a suggestion to discard the food.

[0079] 9D is a diagram showing an example of consumption information 84. Consumption information 84 includes a text message suggesting that the food be discarded, saying, "No nutrients left. Please discard."

[0080] 6, next, in step SP05, the output unit 75 outputs the consumption information generated in step SP04. The communication unit 13 of the information processing device 1 transmits the consumption information input from the output unit 75 to the user terminal 2 via the communication network 4. The communication unit 23 of the user terminal 2 receives the consumption information transmitted from the information processing device 1. The processing unit 21 of the user terminal 2 displays the consumption information received by the communication unit 23 on the display unit 25.

[0081] According to this embodiment, the information processing device 1 acquires condition information of the food to be managed, calculates the deterioration level based on the condition information, calculates the nutrient status based on the deterioration level, generates consumption information based on the nutrient status, and outputs the consumption information. This allows the user to be provided with optimal consumption information based on the nutrient status of the food. As a result, food quality management based on nutrient status can be achieved, and the quality of the user's nutritional management can be improved.

[0082] Furthermore, according to this embodiment, the food contains multiple nutrients, and the nutrient status includes the amount of each of the multiple nutrients, so that optimal consumption information according to the nutrient status of the food containing multiple nutrients can be proposed to the user.

[0083] Furthermore, according to this embodiment, the nutrient status includes the content ratio of multiple nutrients in the food. By including not only the amount of nutrients but also the content ratio of the nutrients in the nutrient status, more useful consumption information can be presented to the user.

[0084] Furthermore, according to this embodiment, the consumption information includes a food preservation method suggestion, which allows the user to be suggested an optimal preservation method according to the nutritional status of the food.

[0085] Furthermore, according to this embodiment, the consumption information includes a recommendation to discard the food, which can suggest to the user that the food be discarded if there is no nutrient remaining in the food.

[0086] Furthermore, according to the present embodiment, the suggestions for how to consume a food item include suggestions for the expiration date of the food item, suggestions for types of dishes that use the food item, and suggestions for how to cook the food item, thereby enabling more appropriate consumption methods to be suggested to the user.

[0087] Furthermore, according to this embodiment, the information processing device 1 calculates the deterioration level of food based on the state information and the first relationship information 61. This can improve the accuracy of calculating the deterioration level.

[0088] Furthermore, according to this embodiment, the information processing device 1 calculates the nutrient status of food based on the deterioration level and the second relationship information 62. This can improve the accuracy of calculating the nutrient status.

[0089] Furthermore, according to this embodiment, the acquisition of the state information includes the acquisition of image information of the appearance of the food, which can improve the accuracy of calculating the deterioration degree.

[0090] Furthermore, according to this embodiment, the acquisition of the condition information includes the acquisition of product information about the food product, including its distribution status, which can further improve the accuracy of the calculation of the deterioration level.

[0091] Furthermore, according to this embodiment, the distribution status includes at least one of the place of production, the date and time of production, the storage method, and the transportation method of the food, which can further improve the accuracy of calculating the deterioration level.

[0092] (Variation) Fig. 10 is a diagram showing a simplified configuration of a recipe providing system according to a modified example of the present disclosure. A cooking appliance 5 is added to the configuration shown in Fig. 1. The cooking appliance 5 includes a stove or an oven.
