- cooking fried foods will be referred to as “deep-frying”
- the edible oil used in deep-frying will be referred to as “deep-frying oil”
- the ingredients to be deep-fryed will be referred to as “fried ingredients”.
- Figure 1 shows a part of the kitchen 1 where deep-frying is performed.
- the fryer 2 is composed of an oil tank 21 for storing frying oil P, and a housing 22 for accommodating the oil tank 21. On the side of the housing 22, there are multiple setting switches 22A for setting the temperature of the frying oil P and the contents of the frying cooking according to the type of frying ingredient Q.
- the fryer 2 determines which setting switch 22A has been operated by the cook, and when the frying time associated with the operated setting switch 22A has elapsed, it notifies the cook that the food is done. At the same time, the fry basket 3 containing the fried food (fried food Q after frying) automatically rises from the oil tank 21, and the fried food is lifted out of the frying oil P from its submerged state.
- the cook senses that the deep-frying is complete, he or she lifts up the fry basket 3 and removes the fried food.
- the fry basket 3 may be automatically lifted from the oil tank 21 by providing a drive mechanism on the fryer 2 side.
- the color of the frying oil P darkens as the heating time passes, and is therefore used as a deterioration index that indicates the degree of deterioration of the frying oil P (hereinafter simply referred to as the "degree of deterioration").
- the deterioration indexes of the frying oil P include, for example, the acid value (AV) of the frying oil P, the polar compound content (PC) of the frying oil P, the viscosity of the frying oil P, the viscosity increase rate of the frying oil P, the anisidine value of the frying oil P, the carbonyl value of the frying oil P, the smoke point of the frying oil P, the tocopherol content of the frying oil P, the iodine value of the frying oil P, the refractive index of the frying oil P, the amount of volatile components of the frying oil P, the composition of volatile components of the frying oil P, the flavor of the frying oil P, the

- the measurement of the deterioration index of frying oil P is not necessarily limited to the above-mentioned measuring device and measuring method, and any known measuring device or measuring method may be used.
- Frying oil P exhibits deterioration characteristics that progress in the direction of deterioration as the heating time or the number of fried items Q increases.
- the deterioration characteristics of this frying oil P are not fixed, but vary depending on the environment and conditions in which the frying oil P is used. Therefore, for example, frying oil P used in the same store will not always exhibit the same deterioration characteristics.
- Figure 2 shows the change in acid value of frying oil P versus heating time [days] for the 1st to 12th cycles at a certain store, where one cycle is defined as the time from when frying oil P goes from new oil to when it becomes waste oil.
- Figure 3 shows the change in color of frying oil P versus heating time [days] for the 1st to 12th cycles at a certain store.

- Figure 5 shows how the color of frying oil P changes in relation to the number of items Q that can be fried in frying oil P for the first to fifth cycles at a certain store.
- x written on the horizontal axis of each of Figures 4 and 5 indicates the number of fried ingredients Q per set, which is predetermined for each store. For example, in a store that sells only croquettes, one set would contain 10 croquettes, and in a store that sells both croquettes and fried chicken, one set would contain 4 croquettes and 5 pieces of fried chicken. By checking the number of sets, deterioration of the frying oil P can be managed.
- Figures 4 and 5 each only show up to 3x pieces (3 sets) of fried frying ingredients Q
- the waste oil P is not necessarily used once every 3x pieces of fried frying ingredients Q are fried, and the frying oil P may continue to be used when frying 4x pieces (4 sets) or more of fried frying ingredients Q.

- the acid value of each frying oil P in the second to fourth cycles also increases differently with respect to the number of frying ingredients Q.
- the color of the frying oil P in the second cycle is about 16 after x number of frying ingredients Q have been fried from the fresh oil state, about 45 after 2x number of frying ingredients Q have been fried from the fresh oil state, and exactly 100 after 3x number of frying ingredients Q have been fried from the fresh oil state

- the monitor 5, store terminal 6, and server 7 of each store are connected to each other directly or indirectly via a communication network N such as an Internet line so that they can communicate information with each other.
- the store terminals 6 in each of the multiple stores are all configured in the same way, so in the following, the store terminal 6 in one store will be used as an example, and a description of the store terminals 6 in the other stores will be omitted.
- the store terminal 6 is an input terminal into which information related to the frying oil P being used in the store and information related to the frying ingredients Q are input, and is also a management terminal that manages the frying oil P being used in the store.
- An application for managing the frying oil P (hereinafter referred to as the "frying oil management app") is installed in the store terminal 6.
- the information related to the frying oil P includes data related to the measurement values of the deterioration indexes of the frying oil P (e.g., the measurement values of the acid value and the color).
- the information related to the frying ingredient Q includes data related to the type and number of the frying ingredient Q fried in the frying oil P.
- the store terminal 6 is communicatively connected to the camera 4 installed in the kitchen 1 in the store, acquires image data captured by the camera 4, and acquires a measurement value of the color of the frying oil P in the oil tank 21 of the fryer 2 based on the acquired image.
- the store terminal 6 and the camera 4 do not necessarily need to be communicatively connected. If the store terminal 6 and the camera 4 are not communicatively connected, the image data captured by the camera 4 is read into the store terminal 6 via an external device, for example. The same applies to the method of acquiring measurement values of deterioration indicators other than color in the store terminal 6.
- the server 7 is one aspect of a deterioration prediction device that predicts deterioration information, which is information relating to the deterioration of the frying oil P, using the measured value of the deterioration index of the frying oil P.
- the server 7 is described as being realized by a server device installed in a headquarters center that oversees multiple stores, as shown in FIG. 6, but it does not necessarily have to be realized by a server device, and may also be realized by, for example, a cloud server constructed on the communication network N.
- the deterioration information includes at least one of the following data: data indicating the remaining time (remaining heating time) until the frying oil P reaches a specified point of waste oil, data indicating the timing to insert or remove the frying oil P from the fryer 2, data indicating the timing to filter the frying oil P from the fryer 2, and data indicating the remaining number of fried items Q that can be fried before the frying oil P reaches a specified level of deterioration.
- “adding and removing” means removing a portion of the frying oil P in the fryer 2 and adding (adding) another frying oil P1 that is different from the frying oil P.
- the "other frying oil P1" does not necessarily have to be new oil, and may be, for example, frying oil that is less deteriorated than the frying oil P in the fryer 2.
- the degree of deterioration of the frying oil P in the oil tank 21 of each fryer 2 progresses in the order of the tempura tank, the breaded side dishes tank, and the fried chicken tank.
- the fried chicken tank may be added with the frying oil P from the tempura tank or the frying oil P from the breaded side dishes tank.

- the deterioration characteristic model of frying oil P corresponds to the graphs showing the deterioration characteristics of frying oil P exemplified in Figures 2 to 5, and since it is possible to predict the deterioration of frying oil P, it can also be called a "deterioration prediction model" of frying oil P.
- the server 7 does not predict deterioration information of frying oil P using a single preset deterioration characteristics model, but instead updates the deterioration characteristics model from time to time and predicts deterioration information of frying oil P using the updated deterioration characteristics model.
- the deterioration standard value of the frying oil P includes at least one of the following standard values: a waste oil standard value that is the standard for the deterioration index of the frying oil P at a specified time of waste oil, a removal and insertion standard value that is the standard for the deterioration index of the frying oil P when it is necessary to remove or insert the frying oil P in the fryer 2, and a filtration standard value that is the standard for the deterioration index of the frying oil P at the time of filtering the frying oil P in the fryer 2.
- These deterioration standards are set to values that correspond to the specifications of the deep-frying process performed in the store, and may be set based on information related to the content of the deep-frying process entered into the store terminal 6, or may be set to arbitrary values by, for example, a store employee.
- Monitor 5 is one aspect of an alarm device that notifies the deterioration information of frying oil P predicted by server 7. For example, when server 7 predicts the remaining time until frying oil P reaches a specified point of waste, monitor 5 displays a message such as "X hours left until the oil is wasted.” In addition, when server 7 predicts the remaining number of fried items Q that can be fried before frying oil P reaches the point of waste, monitor 5 displays a message such as "YY more fried items can be fried before the oil is wasted.”
- the monitor 5 is used to notify the deterioration information of the frying oil P, but this is not limited to the above, and the deterioration information of the frying oil P may be notified using the store terminal 6. Furthermore, the method of notifying the deterioration information of the frying oil P is not limited to a text display, and may be other methods, for example, audio.

- the server 7 updates the deterioration characteristic model of the frying oil P based on the most recent measurement values of multiple deterioration indexes including the latest measurement value of the deterioration index of the frying oil P, and predicts the deterioration information of the frying oil P using the updated deterioration characteristic model, so that even if the usage environment or usage conditions of the frying oil P change, it is possible to obtain prediction results that correspond to the actual progress of deterioration of the frying oil P. Therefore, the server 7 can obtain prediction results with higher accuracy than when predicting the deterioration of the frying oil P using a predetermined deterioration characteristic model.
- the method of predicting deterioration of the frying oil P in the server 7 is also the same for predicting the timing to insert or remove the frying oil P from the fryer 2, predicting the timing to filter the frying oil P from the fryer 2, and predicting the remaining number of fried foods that can be fried before the frying oil P reaches a specified level of deterioration.

- Figure 15 is a table showing the number of data points used in the deterioration characteristic model, the period corresponding to the number of data points, the time from the current point in time to the point at which the oil is wasted, the error, and the error rate for the graph shown in Figure 14.
- the server 7 predicts the remaining time until the frying oil P reaches the waste oil standard value of 2.58 (plot indicated by Y1 in FIG. 14) based on each of the acid value measurements of the frying oil P shown in FIG. 14, up to the acid value measurement value of 1.69 (plot indicated by X1 in FIG. 14) of the frying oil P when the heating time of the frying oil P has reached 120 hours.

- the server 7 can predict the deterioration information of the frying oil P most accurately by using a deterioration characteristic model of the frying oil P updated based on the measured acid value of the frying oil P for the most recent business day acquired by the data acquisition unit 71.
- the server 7 can predict the deterioration information of the frying oil P with the highest accuracy by using a deterioration characteristic model of the frying oil P updated based on the measured acid value of the frying oil P for the most recent business day acquired by the data acquisition unit 71.
- Figure 18 is a graph showing the change in acid value of frying oil P versus the number of business days a store is open.
- the measured acid value of the frying oil P is approximately 0.2, and after two business days the measured acid value of the frying oil P is approximately 0.4, and the frying oil P is gradually deteriorating. After that, after three, four, five, and six business days have passed, the measured acid value of the frying oil P normally increases at a certain rate.
- the server 7 predicts deterioration information of the frying oil P using a deterioration characteristic model of the frying oil P updated based on the measured acid value of the frying oil P for the most recent business day acquired by the data acquisition unit 71, if the measured acid value of the frying oil P for one day on the third business day shown in Figure 18 is used, the prediction result of the deterioration information of the frying oil P will differ from the case where the measured acid value of the frying oil P for one day on another business day shown in Figure 18 is used.
- the deterioration characteristic model of frying oil P is based on the measured acid value of frying oil P for the most recent business day acquired by data acquisition unit 71, there is a possibility that the prediction accuracy of deterioration information of frying oil P in server 7 will be significantly reduced if sales of fried foods on that day happen to be low and deterioration of frying oil P does not progress.
- the server 7 it is desirable for the server 7 to update the deterioration characteristic model of the frying oil P based on the measurement values of the deterioration index of the frying oil P for the most recent two business days at the store, including the latest measurement value of the deterioration index of the frying oil P acquired by the data acquisition unit 71, in order to avoid a decrease in prediction accuracy due to variations in sales of fried foods at such stores.
- the server 7 was described as one aspect of the frying oil P deterioration prediction device, but this is not limited thereto, and the function of the frying oil P deterioration prediction device may be performed by a frying oil management app in the store terminal 6.
- color and acid value are mainly used as examples of deterioration indicators for frying oil P, but this is not limited thereto, and the present invention can be applied even when deterioration indicators other than color and acid value are used.
- the deterioration characteristic model of the frying oil P was a simple regression model expressed in the form of a linear equation, but there are no particular limitations on the type of deterioration characteristic model, and it may be, for example, a linear regression model other than simple regression, such as multiple regression, or a model generated by machine learning.
- the oil and fat is described as frying oil P, but the oil and fat to which the present invention is applied does not necessarily have to be edible oil used for deep-frying, but may be edible oil used for other types of cooking or other oils and fats (industrial oils, etc.).
