Description

  The present invention relates to a recipe customization support system and method for changing a retrieved recipe so that a specific nutrient component approaches a nutrient component value desired by a user.

  In recent years, interest in health has increased, and an increasing number of people are concerned about the nutritional balance of calories and vitamins in their daily diet. Many information on health, such as information on ingredients that are good for the body, is provided on the Web and on TV programs. This has made it relatively easy to cook dishes that help people improve the symptoms they care about. In particular, some websites that offer recipes include the value of calories and key nutrients in each recipe, which is a guideline for users to select a recipe that meets their requirements. Can be.

  Software is also available that calculates the nutritional value of each nutritional component when a menu item is entered. These software have the ability to register new recipes and change the ingredients and quantity in existing recipes. For this reason, the nutritional component value according to a user's actual meal content can be calculated, and a balanced meal can be ingested.

  In ordinary households, cooking is done using the ingredients in the refrigerator. Using these ingredients, users can search the Web and TV programs for recipes that are well-balanced and satisfy themselves.

  On the other hand, recently, so-called Internet home appliances that can be connected to a network and controlled are becoming popular. Internet home appliances include a refrigerator that registers internal materials and manages the expiration date, and a microwave oven that receives information on how to prepare dishes and functions from the stage of preparation. According to such Internet home appliances, it is possible to search for an optimal recipe on the Web from the material information in the refrigerator and transmit the recipe to a microwave oven for cooking.

In Patent Document 1 (Japanese Patent Laid-Open No. 2002-183313), as an example of a system in which a user supplies an optimum recipe that meets his / her conditions, the CPU of the optimum recipe server includes a main dish name desired by a client user and Based on client information such as the appropriate energy intake and recipe determination information such as symptoms of interest and cooking time, it matches the user by combining the main food data, seasoning material data, and side food data. A recipe providing system and a recipe providing method for generating and extracting an optimum recipe to be extracted are described.
JP 2002-183313 A

  The nutritional component values described in the recipes on the website that provides the conventional recipes are those when cooking according to the recipes. When the user changes the type and quantity of ingredients and seasonings according to his / her preference, the nutritional component values differ from those described in the recipe. Therefore, when the user does not cook according to the recipe and arranges the recipe according to his / her preference, there is a problem that the nutritional component values described in advance are not helpful.

  For example, if the software for calculating the nutritional component value is used, the user inputs the ingredients and quantity of the dish that the user wants to register, so the nutritional component value of the dish that the user normally makes can be calculated. However, with such a method, it is not easy to adjust the nutrition balance of the dish to be registered as expected by the user. That is, although the nutrient component value suitable for the user's current recipe can be calculated, it is impossible to know how the nutritional balance is improved.

  If the above-mentioned software is used to make the nutritional balance of the dish that you make as expected, the user will increase or decrease part of the ingredients and amount of the dish, re-register it as a new dish, and calculate It is necessary to repeat the work of confirming the nutrient value. If it is an expert who knows the nutritional component contained in the material, there is no problem, but general users have no such knowledge, and the above work is very complicated and unrealistic. Therefore, the contents of the recipe cannot be easily arranged so as to obtain a nutritional balance desired by general users, and there is a problem in that it is not convenient.

  In the method of Patent Document 1, the recipe is divided and registered into a main dish such as “hamburger”, a seasoning material such as “tomato sauce”, and a side dish such as “mashed potato”. Choose the right combination and compose a recipe. In this method, there is not always a combination that satisfies the user's wishes. In addition, since the registration data itself is not changed, there is a problem that it is not possible to partially change the recipe according to the user's preference.

  Therefore, the objective of this invention is providing the recipe customization assistance system and method which can provide a user with the customized recipe which reflected the partial change of the nutrient component value which a user desires in a recipe.

  In order to solve the above-described problem, in one aspect of the present invention, the reference recipe information that is searched by the user and stores the ingredients used for cooking, the amount of each ingredient, and cooking condition information is changed according to a request from the user. Receiving means for receiving from the user a change request for a nutritional component value for a specific nutritional component of the dish of the reference recipe information, and the material information stored in the reference recipe information according to the change request and the amount of each material Optimal recipe generating means for generating optimal recipe information in which at least one of the information is changed, and recipe providing means for providing the optimal recipe information to the user.

  In another aspect of the present invention, in the method for changing the reference recipe information retrieved by the user and storing the ingredients used for cooking, the amount of each ingredient and the cooking condition information according to a request from the user, the reference recipe information Receiving from the user a request to change the nutritional component value for the specific nutritional component of the cooked food, and at least one of the material information stored in the reference recipe information according to the change request and the quantity information of each material Generating changed optimal recipe information; and providing the user with the optimal recipe information.

  ADVANTAGE OF THE INVENTION According to this invention, the recipe customized by reflecting the partial change of the nutrient value which a user desires in a recipe can be provided to a user.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing a system configuration including a recipe customization support system according to the first embodiment of the present invention. In FIG. 1, a recipe search server 10 searches a storage device 350 (database) for a recipe in response to a request from a user who wishes to view a recipe, and provides the user with a search result recipe. In the recipe, ingredients (food ingredients) used for cooking, the amount of each ingredient, and cooking conditions are described. Hereinafter, the recipe retrieved in this way is referred to as a reference recipe, and the recipe after the change according to a nutritional component value change request described later is referred to as an optimum recipe.

  The reference recipe provided to the user includes a graphical display showing the nutritional component values of the ingredients, which can be changed by the user. For example, when the user makes a request to change the nutritional component value of the specific nutritional component with respect to the reference recipe, the recipe customization support system 20 of the recipe search server 10 can generate an optimum recipe according to the change request. .

  In FIG. 1, first, an Internet network or a mobile phone network from a home terminal 3 such as a PC 3 (personal computer) or a refrigerator 4 in a home, or a user terminal 5 such as a mobile phone 2, a PDA (Personal Digital Assistant), or a digital TV. The recipe search server 10 is accessed via the network 1 to request a recipe desired by the user. The recipe search server 10 having a Web application function searches the storage device 350 in response to a request from the user, and provides the extracted recipe that is the search result to the user terminal 5. Here, when there is a request for changing the nutritional component value from the user terminal 5 with respect to the changeable recipe displayed on the user terminal 5, the recipe search server 10 is a recipe in which the recipe material and the amount of the material are changed, that is, A customized recipe is created and provided to the user terminal 5.

  The recipe search server 10 receives a request from the user terminal 5 at the request receiving unit 12 and provides the received request to the request processing unit 13. The request processing unit 13 first analyzes the type of request provided by the request analysis unit 15, and requests the request according to the type, the recipe search unit 16, the nutrition calculation unit 17, the recipe registration unit 18, and the recipe customization support system 20. Pass to either. The recipe search unit 16 acquires a recipe candidate according to the request from the recipe information 351 stored in the storage device 350. The nutrition calculation unit 17 calculates a nutritional component value based on the recipe selected by the user and the basic nutrition information 353 stored in the storage device 350. The recipe registration unit 18 causes the storage device 350 to store the recipe customized by the user's change request as the recipe information 351 for each user.

  The recipe customization support system 20 generates the optimum recipe by changing the ingredients of the reference recipe, the amount of the ingredients, and the cooking conditions based on the nutrition component value change request from the user and the information stored in the storage device 350. The recipe customization support system 20 will be described in detail later with reference recipe ingredients, the amount of ingredients, and changes in cooking conditions, that is, a specific recipe customization technique.

  The processing results of the recipe search unit 16, the nutrition calculation unit 17, the recipe registration unit 18, and the recipe customization support system 20 are provided to the output unit 14. The output unit 14 sends the processing result to the user terminal 5 and causes the output device of the user terminal 5 to display the result on, for example, a browser. In the recipe search server 10 of this embodiment, the request processing unit 13 includes four types of processing units, that is, a recipe search unit 16, a nutrition calculation unit 17, a recipe registration unit 18, and a recipe customization support system 20. The type of is not limited to these. The output unit 14 may be included in each processing unit in the request processing unit 13. Use of the network 1 is not essential, and a recipe customization support program may be stored on the user terminal 5.

  In this way, the recipe customization support system 20 in the recipe search server 10 changes the ingredients of the reference recipe, the amount of ingredients, the cooking conditions, etc. based on the change request of the nutritional component value from the user, so that cooking after cooking The recipe can be customized to the recipe desired by the user without impairing the taste or texture of the food.

  Next, the configuration and process of the recipe customization support system 20 of the recipe search server 10 will be described in detail. FIG. 2 is a diagram showing the configuration of the recipe customization support system. In FIG. 2, the recipe customization support system 20 of the request processing unit 13 acquires the analysis result from the request analysis unit 15 that analyzes the type of change request from the user. The recipe customization support system 20 changes the recipe material, the amount of the material, and the cooking method based on the acquired analysis result and the information stored in the storage device 350, and provides the changed recipe to the output unit 14. The recipe customization support system 20 first accepts a change request for a nutritional component value from a user by the change request receiving unit 101. Next, the optimum recipe generating unit 102 changes the recipe according to the change request, and the recipe information providing unit 104 changes the recipe and provides it to the outside. When using the function of the recipe customization support system 20, the user accesses the search service site of the recipe search server 10 in advance and displays a desired recipe on the display device (browser) of the user terminal 5. Assuming

  As described above, the recipe customization support system 20 changes the recipe ingredients, the amount of ingredients, the cooking method, and the like based on the detailed change request from the user and the information in the storage device 350. Value recipes can be created.

  Next, a recipe customization support system 20 according to the second embodiment of the present invention will be described. FIG. 3 is a diagram showing a configuration of a recipe customization support system according to the second embodiment of the present invention. In the recipe customization support system 21 of FIG. 3, the same elements as those of the recipe customization support system 20 shown in FIG. The processing until the user transmits a change request is the same as in FIG.

  In the recipe customization support system 21 of FIG. 3, first, the change request receiving unit 201 receives a change request for a nutritional component value from a user. Note that the change request received by the change request receiving unit 201 includes information for specifying a recipe to be customized for recipes in addition to the conditions specified by the user.

  The recipe information acquisition unit 202 acquires recipe information corresponding to the change request from the storage device 350 and provides it to the user terminal 5. The recipe information acquisition unit 202 uses the recipe information 351 based on information for specifying the recipe (for example, the number uniquely assigned to the recipe), such as information on the recipe ingredients, amount, cooking method, and nutritional component value. , And the basic nutrition information 353. Further, in the alternative material selection unit 204, information regarding the material that is the alternative candidate of the material acquired by the recipe information acquisition unit 202 is acquired from the alternative material information 352.

  Next, the optimum recipe generating unit 205 uses the change condition received from the user received by the change request receiving unit 201, the recipe information acquired by the recipe information acquiring unit 202, and the alternative candidate information acquired by the alternative candidate selecting unit 204. Calculate the optimal combination of ingredients, quantity, and cooking method that most closely matches the conditions from the user. The nutritional component calculation unit 206 calculates the nutritional component value after the recipe customization based on the result obtained by the optimum recipe generation unit 205. Finally, the recipe information providing unit 207 and the output unit 14 transmit the results reflecting the recipe customization material, quantity, and nutrient component values to the user terminal 5.

  At this time, the data itself of the recipe information 351 is not changed, and even when the user makes a recipe registration request after the recipe customization, this is registered as a new recipe dedicated to the user. For this reason, the user can easily refer to both the original recipe and the modified recipe.

  In addition, it is possible to add conditions such as not using materials that the user dislikes or using materials that the user likes preferentially at the time of calculation by the optimum recipe generating unit 205. In this case, the optimum recipe generating unit 205 refers to the user profile information 354 including information on the material that the user likes and dislikes. For example, by adding an identifier that uniquely identifies the user to the change request from the user, the user profile information can be acquired from the user profile information 354.

  Alternatively, the user profile information 354 may be stored in the user terminal 5 used by the user, instead of being stored on the recipe search server 10 side. In this case, information about a favorite material and a dislike material is added to the change request from the user, and the optimum recipe generation unit 205 uses the information.

  Furthermore, when the recipe search server 10 is linked to the material management function of the refrigerator, the calculation is performed by the optimum recipe generation unit 205, so that the remainder is obtained by preferentially using the material in the refrigerator. The material can be used effectively. For example, by adding an identifier that uniquely identifies the user to the change request from the user, the material information in the refrigerator owned by the user can be acquired from the material information 355 in the refrigerator. After that, the acquired material information is compared with the recipe information and alternative candidate information, and if the material in the recipe information matches the material information in the refrigerator, the material information in the alternative candidate information is not changed to the alternative material. If the material information matches, the material in the recipe information is changed to the material in the refrigerator, and the combination of the material, quantity, and how to make it as close as possible to the user's conditions may be calculated.

  Further, the optimum recipe generation unit 205 may calculate a plurality of patterns of combinations of recipe ingredients, amounts, and cooking methods. For example, the calculation result when changing only the amount, the calculation result when allowing the use of alternative materials, and the calculation result when changing the cooking method of the material are allowed. Put out. For each of these calculation results, if the nutrient component value is calculated by the nutrient component calculation unit 206 and each result from the recipe information providing unit 207 is displayed on the user terminal 5, the user can select a preference from a plurality of results. Can be selected and used. In addition, it is also possible to preferentially incorporate into the recipe a material having an ingredient that assists in the absorption of the nutritional component requested to be changed by the user. In this case, a combination of a nutritional component of the recipe and a nutritional component that assists in the absorption of the nutritional component, such as vitamin D and calcium, may be stored in the basic nutritional information 353.

  In this way, the recipe customization support system 21 effectively uses the user's change request, the user profile information 354, the food management information 355, and the alternative food information 352 in the storage device 350, and the recipe ingredients and the amount of ingredients, cooking In order to change the method, it is possible to provide the user with a recipe customized to utilize the ingredients in the refrigerator 4 taking into account the user's preferences.

The recipe customization support process will be described in detail below. FIG. 4 shows the flow of recipe customization support processing executed between the user terminal and the recipe search server. First, the recipe search server 10 is accessed from the user terminal 5 by accessing the recipe search site managed by the recipe search server 10. A recipe search request is issued (step S10). The recipe search server 10 searches the recipe information 351 for one or more recipe candidates that match the recipe search request (step S11), and provides the searched recipe candidates to the user terminal 5 (step S12).

  The recipe candidates provided to the user terminal 5 are displayed on the display device (step S13). When one of the recipe candidates displayed on the user terminal 5 is selected as a reference recipe by the user (step S14), the user terminal 5 requests the recipe search server 10 to provide the selected reference recipe (step S15). .

  When receiving the request for the reference recipe, the recipe search server 10 searches the reference recipe with reference to the recipe information 351 (step S16), and provides the searched reference recipe (FIG. 5) to the user terminal 5 (step S17). .

  The user terminal 5 requests customization from the recipe search server 10 based on the provided reference recipe (step S18). The recipe search server 10 provides, for example, a customization recipe that can change the nutrient value of each nutrient component (as shown in FIGS. 6 to 10) to the user terminal 5 (step S19). A request for changing the nutrient value of the specific nutrient component is issued to the recipe search server 10 using the customization recipe (step S20).

  The recipe search server 10 refers to the storage device 350 (alternative material information 352, user profile information 354, material management information 355), and generates an optimum recipe by changing the amount of material and material (step S21). The recipe search server 10 generates a nutrient component value with reference to the nutrition basic information 353 (step S22). The recipe search server 10 provides the generated optimum recipe and nutrient component values to the user terminal 5 (step S23). The user terminal 5 displays the customized recipe and the calculated nutrient value on the display device (step S24).

  In this way, by providing the user terminal 5 with a recipe that can be customized in the recipe search server 10, the change in the nutritional component value of the recipe from the user terminal 5, the user's favorite ingredients, the taste and food after cooking It is possible to customize the recipe desired by the user in consideration of changes to alternative materials that do not impair the feeling.

  Next, an example of a recipe requested by the user terminal 5 will be described. FIG. 5 is a diagram showing a recipe material recipe screen displayed on the user terminal. The recipe screen is divided into a material page and a creation page, and FIG. 5 shows an example of the material page. The material recipe screen 400 shown in FIG. 5 includes a display area 401 displaying the dish name “spring roll”, a display area 402 displaying the material “spring roll”, a completed image 403 of the dish, and a plurality of buttons 404 to 407. It consists of and.

  The button 404 is a button having a function of returning to the top page of the recipe search. The button 405 is a button for requesting the display of a creation page corresponding to the material recipe screen 400. The button 406 is a button for requesting the nutritional component value calculation of the dish described in this recipe and displaying the result. A button 407 is a button for requesting customization of the recipe. When the user selects the button 407, a screen 500 shown in FIG.

  Next, examples of customizable recipes displayed on the user terminal 5 will be described with reference to FIGS. In the screens shown in FIGS. 6 to 10, the same components (display area, button, graph) are denoted by the same reference numerals and description thereof is omitted. FIG. 6 is a diagram showing a recipe nutrition component graph and a material recipe screen.

  A screen 500 shown in FIG. 6 is a radar chart of the nutritional component results of the recipe, a nutritional component graph 501 that can change the value of each nutrient component, a display area 502 that displays the material, and a plurality of buttons 503. 505. The button 504 is a button for displaying the material recipe screen 400. A button 505 is a button for displaying a nutrient component value calculation result. The button 503 is a button for requesting a change in the nutritional component value.

  The nutritional component value calculation result 501 is displayed based on the daily required nutritional amount calculated based on the user's personal information, and the number 1 on the scale is the reference nutritional requirement for the user of each nutritional component. It has become. The user looks at the nutritional component graph 501 and decides the nutritional component to be further consumed and the nutritional component to be reduced, and changes the graph to a value (the shape of the graph) of his / her image. This change is performed by the user using a device such as a mouse. For example, when changing the amount of salt in the nutrient component graph 501 to be reduced, the screen 600 shown in FIG. 7 is displayed.

  FIG. 7 is a diagram showing a screen immediately after the graph shown in FIG. 6 is changed. In FIG. 7, as indicated by a salt value 506 of the nutrient component graph 701 on the screen 600, the value of the graph is changed by the user so as to decrease the amount of salt from the scale 1 to the scale 1. When the button 503 is selected in this state, a recipe change request including the nutrient component value changed by the user is transmitted to the recipe search server 10. The recipe change request is received by the change request receiving units 101 and 201 shown in FIGS. 2 and 3, and is calculated by the optimum recipe generating units 102 and 205 so that the nutritional component balance is close to the user's change request. The calculation results in the optimum recipe generating units 102 and 205 are transmitted to the user terminal 5 via the recipe information providing units 104 and 207, and a screen 700 shown in FIG. 8 is displayed.

  FIG. 8 is a diagram showing a screen on which the change button is selected and the recipe is customized. In the screen 700 shown in FIG. 8, the material and the amount of the material displayed in the display area 702 are changed according to the changed nutrient composition graph 701. In the display area 702, the amount of soy sauce “1/2 tbsp” 708 and the amount of pork “120 g” 707 are changed according to the user's change request (reduction of salt content). Moreover, the nutrition component graph 701 displays the nutrition balance after the recipe change. On this screen 700, a button 706 for registering a customized recipe is newly displayed. The button 706 is a button for registering the contents of the displayed recipe as a user's personal recipe. When this button 706 is selected, the changed recipe is registered as the user's personal recipe. Therefore, from the next time, it becomes possible to make a dish by referring to a personal recipe. In the registered recipe, only the recipe information excluding the personal information of the user may be provided to the general user.

  FIG. 9 is a diagram showing a screen in which the material name is changed in addition to the change shown in FIG. A screen 800 illustrated in FIG. 9 illustrates a case where the optimum recipe generation units 102 and 205 change not only the amount of material but also the material name based on the information in the storage device 350. In the example of FIG. 9, the pork thigh in the display area 707 of the display area 702 shown in FIG. 8 is changed to thin sliced beef as shown in the display area 807 of the display area 802.

  FIG. 10 is a diagram showing a screen in which the method of making is changed in addition to the changes shown in FIG. A screen 900 shown in FIG. 10 further includes a nutrient component graph 901 in which the vitamin A value 903 is changed, a display region 902 in which materials are added in accordance with the change in the nutrient component value, and a display region 904 in which how to make is displayed. It consists of and. FIG. 10 shows an example in which the user makes a change request for vitamin A (increase in vitamin A) and energy (increase in energy) at the same time as salt (increase in salinity). As shown in the display area 909, carrots are newly added to the ingredients of the recipe in the display area 902. Further, when “* (asterisk)” is added in front of the thin sliced meat of the display area 908, this indicates that the cooking method of the material is to be changed. How to make is displayed in the display area 904.

  Next, the customized recipe finally provided from the recipe search server 10 will be described. FIG. 11 is a diagram illustrating a screen displayed as a processing result in the recipe customization support system. In the result screen 1000 shown in FIG. 11, selection is made to select a nutrient component graph 1101 that shows a radar chart of the nutrient component before and after the change of the nutrient component value, and a material display for changing the amount, changing the material, and changing the method of making before the change. An area 1102 to 1105 and a display area 1110 displaying the material change in the selection area 1104 are configured. If you select the selection area 1103, you can see the material that only changes the amount of ingredients in the recipe, if you select the selection area 1104, you can use alternative materials, and if you select the selection area 1105, you can change the recipe. Is displayed.

  Also, by changing the nutrient component graph 1101 with a mouse or the like in the same manner as described above, it is possible to switch to the material display corresponding to the graph. If the user's favorite material is selected and a button 706 having a recipe registration function is pressed, the displayed information can be registered in the recipe information 351 as an individual recipe.

  Thus, since the recipe provided from the recipe search server 10 is displayed on the user terminal 5 and the user can change the nutritional component value, change to the alternative material, or change the method of making, the recipe search server 10 The user can customize and provide a recipe desired by the user. Moreover, since the recipe search server 10 manages the customized recipe with the memory | storage device 350 according to the request | requirement from a user, when a user searches a recipe again, it can provide immediately as a user's original recipe. .

  Next, the configuration in the optimum recipe generating units 102 and 205 shown in FIGS. 2 and 3 will be described in detail. FIG. 12 is a diagram illustrating a configuration of the optimum recipe generation unit illustrated in FIGS. 2 and 3. In the optimum recipe generation units 102 and 205 of FIG. 12, the recipe information acquisition unit 222 acquires the ingredients and the amount included in the target recipe from the recipe information 351, and further, the nutritional component values corresponding to the respective materials are converted into basic nutrition values. Obtained from information 353. The unit of each material described in the recipe is different from each other such as “tablespoon” and “bundle”, but information converted into a unified unit such as “g” in advance is included in the recipe information. Shall. Alternatively, unit conversion may be calculated each time using a unit conversion table for each material as shown in FIG.

  FIG. 13 is a diagram showing a table for unit conversion for each material. 13 includes an item 1301 indicating a material name, an item 1302 indicating a notation unit in a recipe, and an item 1303 indicating the number of grams corresponding to the notation unit in the recipe. The material name item 1301 may be an identifier for uniquely identifying a material, not the material name itself.

  Returning to FIG. 12, after that, the material selection unit 223 selects a material containing the nutritional component that is the target of the user's change request from the information on the nutritional component value of each material. Note that the information acquired by the recipe information acquisition unit 201 may be used without including the recipe information acquisition unit 222 in the optimum recipe generation unit 205. Next, the material division unit determination unit 224 determines the division unit of each material for the material selected by the material selection unit 223. This can be determined from the quantity unit (“tablespoon”, “bundle”, “g”, etc.) and quantity for each material described in the target recipe. For example, in the case of a seasoning or the like, if the rule is “XX tablespoon”, the rule is defined in advance so that the division unit is determined to be equivalent to 1/4 tablespoon, and the division unit is determined according to the definition. . The division unit is an amount that can be easily measured by the user during actual cooking.

  Next, the combination generation unit 225 creates a combination in which one or more of the selected materials are changed according to the previously determined division unit. For example, when there is a request to reduce the salt content by 1 g from the user terminal 5 in the recipe “Japanese style octopus spaghetti”, and the ingredients containing the salt content of the nutritional component value in the recipe are “tarako”, “spaghetti”, “soy sauce” First, the material division unit determination unit 224 determines the material division unit. For example, if it is octopus, the amount corresponding to ¼ belly (25g), spaghetti as an estimated amount per person, 100g, the amount that can be easily divided by the amount of the eye (eg 25g), soy sauce is equivalent to 1/2 tablespoon (9g) Determine the division unit. And the combination of the value which changed one or more of these three types of materials in each division unit is created.

  In the case of this example, since the salt content is required to be reduced, only the combination in which the amount of each material is reduced needs to be generated. That is, the value that this amount can take, 100 (the amount described in the recipe), 75, 50, 25, 0 (g), the value that the amount of spaghetti can take, 400 (the amount described in the recipe), 375, 350,. .., 0 (g), possible value of soy sauce, 54 (amount described in recipe), 45, 36,...

  Next, the nutritional component calculation unit 226 calculates the nutritional component value of the recipe for each combination from the generated amount of each combination of cod roe, spaghetti, and soy sauce, and other ingredients and amounts in the recipe. Finally, the optimum recipe selection unit 227 sets a solution that is closest to the user's change request and has other nutritional component value changes within a predetermined range.

  The predetermined range is defined as, for example, a value that is 0.8 to 1.2 times the original nutrient value. When a combination is generated by the combination generation unit 225, the number of combinations can be reduced by setting an upper limit and a lower limit of the amount of each material in advance. In this case, information on the upper limit and lower limit of the amount of the material may be stored in the basic nutrition information 353 or the alternative food information 352.

  In addition, when there is information on the taste of seasoning in the user profile information 354 of the user, for example, there is a description that the seasoning of dark eyes is a preference, when reducing the seasoning, the amount of other materials accordingly It is also possible to set a rule for changing the value so as to be close to a deep seasoning.

  The above example is an example of changing only the amount of the material in the recipe, but the material to be changed is selected from the alternative material candidates, and the combination when each material is changed to the alternative material is added to the calculation target You can also. Moreover, when a user's user profile information 354 contains a material which a user dislikes in a recipe, the material can be changed to an alternative material and nutritional component value calculation can be performed.

  Next, another example of the nutritional component value determination method that satisfies the change request from the user will be shown. In the present embodiment, for each stored recipe, a table is recorded in advance that records examples of combinations of materials, amounts, and the like when a part of the nutrient value is changed. That is, several patterns are set in advance for the original recipe, such as a combination of ingredients with 1 g less salt, a quantity, etc., a combination with ingredients less than 2 g, a quantity, etc., a material with 20 mg of calcium, a combination of quantities, etc. ing. A specific example in the case where the material, quantity, etc. are changed according to this pattern will be described with reference to FIG.

  FIG. 14 is a diagram showing a recipe information table when the nutrient component value is changed. In FIG. 14, the recipe information table 1400 when the nutrient component value is changed includes an original recipe identifier 1401, a change target nutrient component name 1402, a change target nutrient component value 1403, and a recipe customization method type 1404. And recipe information 1405 corresponding to the recipe identifier 1401 that is changed according to the change conditions 1402 to 1404. In the recipe information table 1400, the nutrient component value 1403 to be changed describes the difference from the nutrient component value of the original recipe, but this may be determined so as to describe the nutrient component value itself. The type of recipe customization method 1404 is for distinguishing whether the change method is “change only the amount of the original recipe material”, “use alternative material”, or “change how to make”. Information is stored.

  In this way, by using the unified unit and division unit of the amount of material, by determining the combination of each material and the amount and method of changing the material, it was customized without impairing the taste and texture of the cooked food A recipe can be provided to the user.

  In the example of FIG. 14, only the description “amount” indicating that “only the amount of the original recipe material has been changed” is shown. However, labels such as “alternative” and “how to make” may also be used. Good. Then, when there is a change request for the nutritional component value from the user, the table 1400 is searched for a pattern corresponding to the target recipe and close to the change request. If there is no pattern in the table that satisfies the change request from the user, for example, the material, amount, etc. that satisfy the request may be calculated by the method shown in FIG. The calculated solution can be stored in the table 1400 as a new pattern of the target recipe.

  In this manner, recipe patterns calculated based on change requests from various users are added to the table 1400, so that a plurality of users can be calculated without repeatedly calculating combinations of material information satisfying the change requests. Can provide customized recipes.
