The deriving device 1 further includes input means 14 such as a mouse and a keyboard, and output means 15 such as a monitor and a printer.

  A part of the recording area in the recording means 12 is a cooking database (cooking DB) 12a for recording information related to cooking, a food database (food DB) 12b for recording food information relating to food used for cooking, and a nutrient for food. It is used as various databases such as a nutrient database (nutrient DB) 12c in which information is recorded. Instead of using the recording area of the recording means 12 as various databases, various tables may be formed in the recording area of the recording means provided in another device connected to the derivation device 1.

  FIG. 2 is an explanatory diagram conceptually showing an example of the recorded contents of the dish database 12a provided in the derivation device 1 of the present invention. In the cooking database 12a, various types of information such as food name, serving amount, cooking conditions, and the like are recorded in association with cooking information such as a cooking name indicating cooking. As cooking conditions, a cooking method and cooking time are recorded. The cooking method includes “baking”, “simmering”, “steaming”, and the like. In the example shown in FIG. 2, ingredients such as “potato”, “beef”, and “curry powder” are used for the dish “curry”. And the amount of the ingredient “potato” for one person is “20 g”, and the cooking “boil” is performed for “3 hours”. It is also possible to record the cooking conditions for multiple steps, such as cooking “beef” for “5 minutes” followed by “simmering” for “2 hours 55 minutes”. is there. It is also possible to add cooking conditions such as cooking temperature and cooking equipment to be used.

In the food material database 12b, food material information such as the state of the usable food material, the production area, the production time, and the like, and the stock amount of the food material are recorded in association with the food material name indicating the food material. The state of the foodstuff indicates a state relating to storage such as “raw” and “frozen” and a state indicating a production stage such as “processing”. As the production area, it is also possible to use names such as a manufacturer name, a factory name, etc., in addition to a region name such as “Hokkaido” and a country name such as “Australia”. As the production time, information indicating the time such as “mid-April” or “October 2008” is used. The contents of each item are recorded in the food database 12b by inputting in advance, but sequential input for all items is not always necessary, and the recording contents of other items related to the same record and the derivation device 1 May be automatically set based on a preset reference based on the time indicated by the internal calendar included in the. For example, when the ingredient “potato” is produced in “Hokkaido” and the state is “raw”, and the internal calendar indicates July 2, the ingredient is determined to have been harvested in the current year. The production time is set to “mid-April”.

  FIG. 4 is an explanatory diagram conceptually showing an example of the recorded contents of the nutrient database 12c included in the derivation device 1 of the present invention. In the nutrient database 12c, various information such as food name, state, production area, production time, cooking method, and nutrient content of the food are recorded in association with each other. The food name, state, production area, production time, and cooking method correspond to each information recorded in the food database 12b. As the nutrient content of the food material, the nutrient content and the nutritional value (energy) such as protein, lipid, and carbohydrate are recorded as the nutrient content per unit amount of 100 g of the food material. A method of deriving the content instead of the nutrient content may be recorded. In the item of content of nutrients illustrated in FIG. 4, a portion where characters other than numerical values such as graph 1, formula 1, and table 1 are described is a method for deriving the content, and a method for deriving the content Is used when the content cannot be shown as a fixed value, such as when the content changes with cooking time. As is clear from the database configuration illustrated in FIG. 4, in the present invention, the content of the food is recorded for each condition such as the state, the production area, the production time, the cooking method, and the content corresponding to the condition. Can be derived. In the present invention, conditions other than those illustrated in FIG. 4 can be set as necessary. For example, when nutrients change over time after production, items such as post-production elapsed time are set. You may do it.

  A method for deriving the content recorded in the nutrient database 12c will be described. FIG. 5 is a graph used by the deriving device 1 of the present invention to derive the nutrient content. The graphs illustrated in FIGS. 5A to 5C are graphs shown as the graph 1, the graph 2, and the graph 3 in the food database 12 b and are recorded in the recording unit 12 in advance. For example, when it is shown as the graph 1 in the food material database 12b, the graph 1 shown in FIG. 5A recorded in advance in the recording means 12 is extracted, and the content is derived using the extracted graph 1. . In the graphs shown in FIGS. 5A to 5C, the horizontal axis represents the cooking time, and the vertical axis represents the content. When deriving a nutrient, the corresponding content can be derived from the cooking time of the food to be derived based on the relationship shown in the graph. In addition, although the vertical axis | shaft is shown as content here, you may make it derive | lead-out by multiplying the content rate calculated | required from a graph to the reference amount set beforehand by making a vertical axis | shaft into a content rate.

  When the method of deriving the content as information such as Formula 1, Formula 2, Formula 3, etc. is recorded in the food material database 12b, the formula as shown in Formula 1 below is used.

  y = f (x) ... Formula 1

  In Equation 1, the explanatory variable x indicates cooking time, and the objective variable y indicates the nutrient content. For example, f is a function that is appropriately set by formulating the graph shown in FIG. Formulas such as Formula 1, Formula 2, Formula 3 and the like are recorded in advance in the recording unit 12. For example, when the formula 1 is shown in the food database 12b, it corresponds to Formula 1 recorded in the recording unit 12 in advance. The mathematical expression to be extracted is extracted, and the content is derived using the extracted mathematical expression.

  When the method of deriving the content as information such as Table 1, Table 2, and Table 3 is recorded in the food material database 12b, for example, a table showing the content at intervals of 5 minutes is used. Such a table is, for example, a table that is appropriately set by converting the mathematical formula shown in the graph shown in FIG. Tables such as Table 1, Table 2, and Table 3 are pre-recorded in the recording means 12, and correspond to Table 1 pre-recorded in the recording means 12 when, for example, shown as Table 1 in the food database 12b The table to be extracted is extracted, and the content is derived using the extracted table.

  Next, processing of the derivation device 1 of the present invention will be described. FIG. 6 is a flowchart showing a processing example of the derivation device 1 of the present invention. The nutritionist operates the deriving device 1 of the present invention and inputs the dish information indicating the name of the dish that is the target of the nutrition deduction. The deriving device 1 receives input of cooking information from the input unit 14 under the control of the control unit 10 that executes the computer program 100 of the present invention stored in the storage unit 13 (step S1). The input in step S1 can be input by various methods such as direct input of dish information and selection from a plurality of previously presented dish information. In addition, when there are a plurality of ingredients used for cooking, for example, when “frozen” “potato” and “raw” “potato” are present, cooking any desired food is possible. When it is possible, at the stage of step S1 or at the stage of deriving the ingredients to be described later, an input for selecting the ingredients to be used is performed.

  Under the control of the control means 10, the deriving device 1 derives the ingredients, the amount of use, and the cooking conditions from the received dish information based on the recorded contents of the dish database 12a (step S2). In step S2, for example, when “curry” is input as the cooking information, the derivation device 1 includes ingredients such as “potato”, “beef”, and “curry powder” recorded in association with “curry”, By reading the usage amount of the ingredients and the cooking conditions of each ingredient, that is, the cooking method and cooking time, from the cooking database 12a, the ingredients, the usage quantities and the cooking conditions are derived. In step S2, instead of automatically executing the subsequent processing using the derived ingredients, usage amount and cooking conditions, the derived contents are output and can be appropriately modified. Also good. In particular, when there are a plurality of foods that can be used as described above, input related to the correction may be performed by appropriately selecting from the available foods.

  Under the control of the control means 10, the deriving device 1 derives food information such as the state of the food, the production area, and the production time from the food derived in step S2 based on the recorded contents of the food database 12b (step S3). . In step S3, the deriving device 1 determines the state of “raw” and the like recorded in association with the ingredients such as “potato” derived in step S2, the production area such as “Hokkaido”, “mid-April”, and the like. By reading the production time from the food database 12b, the food information such as the state, the production area, the production time and the like is derived. In step S3, instead of automatically executing the subsequent processing using the derived food material information, the derived contents may be output and appropriately modified.

  Under the control of the control means 10, the deriving device 1 is based on the recorded contents of the nutrient database 12c from the cooking method derived in step S3, the cooking conditions such as the cooking time, and the food information such as the state, production area, and production time. The content for each nutrient per unit amount of each food material is derived (step S4). In step S4, the derivation device 1 reads the content per unit amount recorded in association with the cooking condition and the ingredient information derived in step S3 for each nutrient from the nutrient database 12c. Derive the nutrient content per unit amount. When the content recorded in association with the content is a value indicating the content itself such as “100 (kcal)” or “1.5 (g)”, the derivation device 1 uses the value as the content. To derive. Further, when the content recorded in association is a method for deriving the content of graph 1, formula 2, table 3, etc., the deriving device 1 derives the cooking time and content as cooking conditions. From the relationship, the content corresponding to the cooking time is derived. In step S4, instead of automatically executing the subsequent processing using the derived content, the derived content may be output and appropriately modified.

  The deriving device 1 is used for cooking from the use amount of each food derived in step S2 and the content of each nutrient per unit amount of each food derived in step S4 under the control of the control means 10. The content of each nutrient for each ingredient is calculated (step S5). For example, the nutritional value (energy) of the ingredient “potato” for the dish “curry” is “20 (g)” for one serving, and the content of nutritional value per 100 g which is a unit amount is “70 (kcal)” Therefore, it is calculated by the following formula 2.

  20 g × 70 kcal / 100 g = 14 kcal Equation 2

  In addition, the nutrient “vitamin A” of the ingredient “potato” for the dish “curry” is “20 (g)” for one serving, and the content of nutrients per 100 g as a unit amount is “5 (μg)”. Therefore, it is calculated by the following formula 3.

  20 g × 5 μg / 100 g = 1.0 μg Formula 3

  And the derivation | leading-out apparatus 1 totals the content for every nutrient with respect to each foodstuff used for the cooking calculated in step S5 by control of the control means 10 (step S6), and the content for every nutrient with respect to each foodstuff and cooking The content of the nutrients for is output from the output means 15 (step S7). The output in step S7 is, for example, an output such as display on a monitor or printing from a printer. Note that when another device is connected to the derivation device 1 via, for example, a LAN, transmission to the other device may be used as an output.

  FIG. 7 is a chart showing the nutrient content output from the derivation device 1 of the present invention. As shown in FIG. 7, the content for each nutrient for each ingredient and the content for each nutrient for a dish are shown as a list. The dietitian makes a menu with reference to the output chart shown in FIG.
