The present invention relates to a measurement method and a fats and oils deterioration degree measurement program.

Conventionally, frying using edible oil, which is a type of fat, has been widely used as a simple and flavorful cooking method. It is necessary to grasp the degree of deterioration and replace it at the appropriate timing.
One form of degraded edible oil is a state in which the amount of free fatty acids has increased due to decomposition of fats and oils.
Here, according to JIS-K0070, the number of mg of potassium hydroxide required to neutralize the free fatty acid contained in 1 g of oil and fat is defined as "acid value", and the acid value is the deterioration of edible oil. It is generally used as a chemical deterioration index when judging the condition.
For example, in the case of edible oil for commercial use (side dishes, school lunches, etc.), the sanitary norms of the Ministry of Health, Labor and Welfare instruct that the edible oil should be replaced at an acid value threshold of 2.5.

However, in order to accurately measure the acid value, special equipment and chemicals are required, and it is not realistic to use the above equipment and chemicals when managing the degree of deterioration of fats and oils on a daily basis at cooking sites. isn't it.
Therefore, as a simple acid value measurement method, a measurement method using a color test paper with an indicator is widely known, and among the measurement methods, there is a solution to the problem of individual differences in judgment of measurement results. Therefore, an apparatus capable of measuring the acid value of the target fat to be measured at a practical level has been proposed (for example, Patent Document 1).

In the system for measuring the degree of deterioration of edible oil described in Patent Document 1, a terminal device such as a smartphone captures a color test paper immersed in the target oil based on user operation, and the color information of the color test paper is included. Acquisition of photographed data and transmission of the photographed data to the data server. Then, the data server measures the acid value, which is an index of the degree of deterioration of the oil, by comparing the color information of the color test paper included in the photographed data with the information stored in advance, and measures the acid value of the target oil. Result data indicating the result of measurement of the value and chromaticity value and the determination result of the acid value threshold value indicating a tentative guideline for replacement of the edible oil is transmitted to the terminal device. Then, it is disclosed that the terminal device outputs and displays the contents of the result data on the display screen.
With the above configuration, it is possible to easily measure the acid value and chromaticity value of the edible oil to be measured with practically acceptable accuracy using a general-purpose device such as a smartphone.

An automatic photographing processing unit 22 for taking a photograph is provided.
The "acid value reference data" shown in FIG. 4 is created by the color information calculator 15, and the "category reference data" shown in FIG.
These include a CPU, ROM, RAM, HDD, communication interface, various programs, and the like.

The data server 100 will also be described from the functional aspect. A transmission unit 111 and a data reception unit 112 are provided as main components.

The “acid value threshold data” stored in the storage unit 10 is, as shown in FIG. 3 , table data indicating the correspondence between the object of use of fats and oils and the acid value thresholds of fats and oils.
Here, the "objects using oil" are, for example, objects (objects to be fried) that are cooked using edible oil, such as boxed lunches and side dishes, fried tofu and karinto.
The "acid value threshold" indicates the state in which the color and odor of the oil changes when the value is exceeded, indicating that the deterioration of the oil has already progressed, and serves as a reference for when to replace the oil. .
Looking at the present embodiment in FIG. 3, the object of use of oils and fats, "Bento and side dish" is set for the acid value threshold "2.5", and for the acid value threshold "3.0" It can be seen that the object of use of fats and oils is set as “fried tofu, karinto”.

The acid value threshold varies in speed of deterioration (speed of acid value) depending on the object of use of the oil. Specifically, the rate at which free fatty acids and the like are produced by hydrolysis differs depending on the amount of water released from the object to be fried during the frying process. Moreover, the thermal polymerization and thermal decomposition rates of fats and oils differ depending on the frying temperature of the object to be fried.
Therefore, the user can set an appropriate acid value threshold according to the difference in the object of use of the oil in consideration of the circumstances of the site where the oil is handled, thereby leading to a more accurate determination result.

In addition, according to the "acid value threshold data" shown in FIG. 3, the relationship between the type of fat, the location and frequency of use of the fat, and the acid value threshold of the fat is also shown.
As for the acid value threshold, the rate of deterioration also differs depending on these differences. Therefore, considering the circumstances of the site where oils and fats are handled, the user can set an appropriate acid value threshold by combining the type of oil and fat, the location of use, and the frequency of use. By setting, it is possible to derive a more accurate determination result. Alternatively, any one of the above factors can be used alone to set an appropriate acid value threshold.
It is desirable to classify the 'places where fats and oils are used' into, for example, food stores that handle fats and oils, food manufacturing factories, and the like.
As for the "frequency of use", it is desirable to classify, for example, relatively high frequency of use, normal, and low frequency of use.

The "acid value reference data" stored in the storage unit 10 is, as shown in FIG. It is graph data in which RGB color information (red value (RED), green value (GREEN), and blue value (BLUE)) is set on the vertical axis.
Specifically, the acid value reference data is data that can be created by calculating RGB color information of the color bar 3 having colors corresponding to acid values of 0.0 to 4.0.
Here, "RGB color information" is color information represented by the three primary colors of red, green, and blue, and indicating the luminance of each color with a value of 0-255. 0 means that the color is not included and 255 means that the intensity of that color is maximum. Therefore, R (RED): 0, G (GREEN): 0, B (BLUE): 0 for black, and R: 255, G: 255, B: 255 for white.

According to the "acid value reference data" in FIG. 4, specific corresponding values between the acid value and the RGB color information by the color bar 3 are as shown in Table 1 below.

The "category reference data" stored in the storage unit 10, as shown in FIG. This is data for assigning to a predetermined category according to the magnitude of , and is data created from the "acid value reference data" shown in FIG.
"Category reference data" is graph data with acid value set on the horizontal axis and BLUE-RED color difference (BR color difference) on the vertical axis. ing.

ここで、カテゴリー「酸価０．０」とは、酸価が０．０であることを意味し、また、例えば、カテゴリー「酸価０．５－１．０」とは、酸価が０．５超１．０以下の範囲で取り得ることを意味している。 As for the method of assigning categories, according to the rules in Table 2 below obtained from the "category reference data" in FIG.

Here, the category "acid value 0.0" means that the acid value is 0.0, and for example, the category "acid value 0.5-1.0" means that the acid value It means that it can be in the range of more than 0.5 and 1.0 or less.

The threshold value setting unit 11 receives an input of a predetermined use object by user operation, refers to the acid value threshold data shown in FIG. 3, and sets an acid value threshold for the predetermined use object.
Specifically, first, the input of the touch panel operation of the "setting" button by the user is received on the initial screen shown in FIG. 1, and the setting information screen shown in FIG. 6 is displayed. Then, the input of the "threshold" button by the user is received on the setting information screen, and a threshold setting screen (not shown) is displayed. Then, by receiving input (selection) of the "predetermined use object" by user operation on the threshold setting screen, the acid value threshold for the predetermined use object is set.
With the above configuration, the user can freely change the acid value threshold based on the judgment criteria of the site where oils and fats are handled.
In addition, when there is no input by the user operation, the threshold setting unit 11, when measuring the deterioration degree of the target oil for the first time, as shown in FIG. A corresponding acid value threshold value of 2.5 is set, and when the second and subsequent measurements are performed, the already set acid value threshold value is set again.

The threshold change unit 12 accepts the input of the user's operation and changes the acid value threshold indicated by the acid value threshold data in FIG. 3 to a threshold corresponding to the input of the user's operation.
Specifically, first, the input of the touch panel operation of the "setting" button by the user is received on the initial screen shown in FIG. 1, and the setting information screen shown in FIG. 6 is displayed. Then, the input of the "threshold" button by the user is received on the setting information screen, and a threshold setting screen (not shown) is displayed. Then, an input of a "predetermined threshold value" by a user's operation is accepted from the threshold value list of 0.0 to 4.0 displayed on the threshold setting screen, and the threshold value is changed to the predetermined threshold value.
With the above configuration, the user can freely change the acid value threshold based on the judgment criteria of the site where oils and fats are handled.

The user notification unit 13 displays a predetermined sign on the display screen in advance when accepting an input of a user operation for executing imaging by the test piece imaging unit 1a, thereby indicating that the input of the user operation can be accepted. It informs the user of the waiting time until it becomes.
Specifically, when the user's touch panel operation input of the "shooting start" button (corresponding to the central portion of the screen) is accepted on the initial screen of FIG. 1, a predetermined alarm indicator 1e is displayed as shown in FIG. A user notification screen is displayed to notify that input of user operation cannot be accepted until a predetermined waiting time (for example, 30 seconds) elapses. Then, after 30 seconds have passed since the display of the user notification screen, the screen is automatically switched to a photographing screen (not shown) for executing photographing.
The alarm indicator 1e is a clock mark indicator displayed on the upper right of the display screen, and disappears from the screen after 30 seconds have passed. By displaying the number of seconds for the countdown together with the alarm indicator 1e, it is possible to notify the user in an easy-to-understand manner.
According to the user's notification, it is usually necessary to wait about 30 seconds for the coloring reaction to complete after soaking the coloring test piece 2 in oil. You can let us know without hesitation.

The photographed data acquisition unit 14 acquires photographed data (not shown) obtained by simultaneously photographing the coloration test piece 2 and the color bar 3 immersed in the target oil and fat.
Specifically, by receiving a user's touch panel operation input of a "shooting execution" button on a shooting screen (not shown), shooting is executed and shooting data is acquired.
When acquiring the shooting data, it is determined whether or not the shooting data satisfies preset shooting standards. The user is notified to do so, and the screen is returned to the shooting screen.
As a specific shooting standard, as the first standard, the image of the shooting data is binarized (converted into two gradations of white and black), and when area detection is performed by labeling (continuous white part When the same numbers are assigned to the samples), it is determined that the number of detected areas is 7 (the test piece area is 1 and the color bar area is 6). As a second criterion, it is determined whether the color bar 3 is separated from the center of gravity of the coloring test piece 2 by a predetermined distance. As a third criterion, it is determined whether or not the color bar 3 is tilted by a predetermined angle or more. As a fourth criterion, the color test piece 2 and the color bar 3 are checked for foreign matter and shine.
If any one of the first to fourth criteria is not met, the user is requested to take a picture again.

The color information calculator 15 calculates the RGB color information of the coloration test piece 2 and the color bar 3 from the photographed content indicated by the photographed data. Create "acid value reference data" shown.

The category assignment unit 16 assigns the acid value of the target oil and fat to the acid value from the calculated RGB color information of the color bar 3 and the calculated RGB color information of the color test piece 2 corresponding to the acid value. It is assigned to a predetermined category among a plurality of categories classified based on size.
Specifically, the "category reference data" in FIG. 5 was created from the "acid value reference data" in FIG. Based on the BR color difference, the acid value of the target oil is assigned to a predetermined category out of the seven categories according to the rules described above.
For example, if the BR color difference of the target fat to be measured is −68, the BR color difference is −65 or less and exceeds −95, so the acid value of the target fat is classified as “acid value 2.0-3 .0”. At this time, it means that the acid value of the target fat and oil is in the range of more than 2.0 to 3.0 or less.

The acid value measurement unit 17 refers to the acid value reference data in FIG. 4 and the category reference data in FIG. The acid value of the target oil is measured from the information (BR color difference).
In other words, the acid value of the target fat is calculated in units of 0.1.
In the case of category "acid value 0.0" and category "acid value 4.0", acid value 0.0 and acid value 4.0 are used as the measurement results.
Specifically, the acid value is calculated using the following formula.
"a formula":
Acid value = ((BR color difference of color test piece - BR color difference on low acid value side) ÷ (BR color difference on high acid value side - BR color difference on low acid value side)) × Notch interval + acid on low acid value side Here, "BR color difference on the low acid value side" means the lower limit close to 0.0 in a given category, and "BR color difference on the high acid value side" means It means the upper limit on the side close to 4.0.
By "notch interval" is meant the difference between the upper and lower acid number values in a given category.

For example, if the RGB color information of the target oil is R: 104, G: 116, B: 36, the BR color difference is -68, and the category is "acid value 2.0-3.0", the following calculation formula The acid value can be calculated by
The BR color difference at an acid value of 2.0 is -65, and the BR color difference at an acid value of 3.0 is -95.
Acid value = (("-68" - "-65") ÷ ("-95" - "-65")) x "1.0" + 2.0, the acid value is 2.1 Calculated.
By using the above formula, it is possible to calculate the acid value by taking into account whether the acid value of the target oil is placed on the low acid value side or the high acid value side in the predetermined category.

The threshold determination unit 18 determines whether or not the acid value of the target fat measured by the acid value measurement unit 17 is equal to or higher than the acid value threshold set by the threshold setting unit 11 .
Specifically, when the acid value of the target fat is less than the acid value threshold value, the determination result of ◯ is displayed, and the user is informed that the target fat can be used continuously. On the other hand, if the acid value is equal to or higher than the threshold value, the determination result of x is displayed, and the user is informed that the target oil should be replaced with a new one.
For example, if the acid value of the target fat is 2.1 and the acid value threshold is set to 2.5, the acid value of the target fat is less than the acid value threshold. will be shown.
Note that the determination result is not limited to "○" or the like, and any notification means may be used as long as the user can understand it.

The prediction unit 19 determines the time when the acid value of the target fat is equal to or higher than the acid value threshold (for example, the usable time ).
Specifically, as shown in FIG. 8, the history information of the target oil and fat includes information such as "photographing date", "acid value measurement value", and "judgment result". The time (usable time) is predicted by using a known technique.

For example, a plurality of pieces of history information shown in FIG. It is possible to predict the usable time by using a predictive method.
The information predicted by the prediction unit 19 is not limited to information about when the acid value is equal to or higher than the threshold. You may predict the advice information etc. about an acid value measurement. Alternatively, information about the number of remaining usable times may be predicted.

The output unit 20 outputs the determination result data shown in FIG. 9 including the measured acid value of the target oil, the determination result determined by the threshold determination unit 18, and the usable time predicted by the prediction unit 19 to the user. It is intended to output and display toward.
Specifically, as shown in FIG. 9, the measurement result of the target oil is “acid value 2.1”, and the determination result is “○” and the acid value threshold is less than 2.5. In addition, as a result of prediction, information regarding the usable time is displayed, such as "can be used until approximately XX days."
In addition, the determination result data includes information such as the date and time of measurement and the shooting content of the shooting data. When the user wants to check detailed information, a detailed information screen (not shown) is displayed by receiving the user's touch panel operation of the "details" button on the screen on which the judgment result data shown in FIG. 9 is displayed. can do.

With the above configuration, the device can measure the degree of deterioration of fats and oils and output determination results with a simple configuration without being affected by differences in shooting environments.
In addition, it is possible to set the acid value threshold of the target fats and oils in consideration of the circumstances of the site where the fats and oils are handled, and to output the determination result.
In addition, the measurement can be intuitively and easily understood by the user, and useful information can be displayed together with the display of the measurement result.

<Oil deterioration degree measurement program>
Next, the processing of the fats and oils deterioration degree measuring program executed by the fats and oils deterioration degree measuring device 1 will be described with reference to FIG. 10 .
The program according to the present embodiment includes the threshold setting unit 11, the threshold changing unit 12, the user notification unit 13, and the photographing Various programs are integrated to realize the data acquisition unit 14, the color information calculation unit 15, the category assignment unit 16, the acid value measurement unit 17, the threshold determination unit 18, the prediction unit 19, and the output unit 20. The CPU of the oil deterioration degree measuring device 1 executes this oil deterioration degree measurement program.
The program is executed upon receipt of an operation instruction from a user.
3, "acid value reference data" shown in FIG. 4, "category reference data" shown in FIG. The past "determination result data" shown is stored.

10, the threshold value setting unit 11 first refers to the acid value threshold data shown in FIG. .
Specifically, an input of a predetermined object to be used by a user operation is received, acid value threshold data is referred to, and an acid value threshold corresponding to the predetermined object to be used is set.
If there is no user input, set the initial setting value when measuring the degree of deterioration of the target oil for the first time, and set the already set acid value threshold again when measuring the degree of deterioration of the target oil after the second time. (for example, the acid value threshold is 3.0, the object of use of fats and oils: deep-fried tofu, Karinto).

Next, in step S2, when the threshold changing unit 12 receives input of a predetermined user operation, the acid value threshold is changed according to the input of the user operation (step S3).
Specifically, when the input of the user operation is accepted (step S2: Yes), the process proceeds to step S3, and the acid value threshold according to the input of the user operation (for example, the acid value threshold: 2.5, the object of use of fats and oils : bento and side dishes).
On the other hand, when the input of the user's operation is not received (step S2: No), the process proceeds to step S4 without changing the acid value threshold value.

Next, in step S4, the user notification unit 13 displays a predetermined sign on the display screen in advance when accepting an input of a user operation for executing photographing, thereby indicating that the input of the user operation can be accepted. The user is notified of the time until it becomes.
Specifically, a user notification screen with a clock mark sign is displayed to notify that user operation input will not be accepted until a waiting time of, for example, 30 seconds has elapsed. After 30 seconds have passed, the screen is automatically switched to a photographing screen for executing photographing.

Next, in step S5, the photographed data acquisition unit 14 acquires photographed data (not shown) in which the color test piece 2 immersed in the target oil and the color bar 3 are simultaneously photographed.
More specifically, by receiving an input from the user's "execute photographing" button, photographing is executed and photographing data is acquired.

Next, in step S6, the color information calculation unit 15 calculates RGB color information of the coloration test piece 2 and the color bar 3 from the photographed content indicated by the photographed data.
Specifically, the RGB color information of the color test piece 2 (for example, R: 104, G: 116, B: 36) and the RGB color information of the color bar 3 are calculated, and from the RGB color information of the color bar 3 The "acid value reference data" shown in FIG. 4 is created.

Next, in step S7, the category assigning unit 16 creates "category reference data" in FIG. 5 from the "acid value reference data" in FIG. From the RGB color information of 2, the acid value of the target fat is assigned to a predetermined category among a plurality of categories classified based on the magnitude of the acid value.
Specifically, the BR color difference is calculated from the RGB color information of the colored test piece 2 and assigned to a predetermined category from the BR color difference (for example, if the BR color difference is −68, if the BR color difference is −65 or less, -95, assign the category "acid number 2.0-3.0").

Next, in step S8, the acid value measurement unit 17 refers to the "acid value reference data" in FIG. 4 and the "category reference data" in FIG. The acid value of is calculated in units of 0.1.
Specifically, the acid value is calculated using the following formula.
Acid value = ((BR color difference of color test piece - BR color difference on low acid value side) ÷ (BR color difference on high acid value side - BR color difference on low acid value side)) × Notch interval + acid on low acid value side Value For example, if the BR color difference of the target fat is -68 and the category is "acid value 2.0-3.0", the acid value is calculated as 2.1.
In addition, in the case of the category "acid value 0.0" and the category "acid value 4.0", the acid value is calculated as 0.0 and 4.0 as they are.

Next, in step S9, the threshold determination unit 18 determines whether or not the measured acid value of the target fat is equal to or higher than the acid value threshold.
Specifically, when the acid value is less than the threshold value, the judgment result of ◯ is shown, indicating that the target oil can be used continuously. On the other hand, when it is equal to or higher than the acid value threshold value, the determination result of x is displayed, indicating that the target oil should be replaced.
For example, when the acid value is 2.1 and the acid value threshold value is 2.5, the acid value is less than the acid value threshold value, so the determination result of “◯” is shown.

Next, in step S10, the prediction unit 19 determines the time when the acid value of the target fat is equal to or higher than the acid value threshold (for example, the usable time) from the history information of the target fat obtained from a plurality of past determination result data. Predict.
Specifically, from information such as “photographing date”, “acid value measurement value” and “judgment result” as history information of the target fat, by combining these elements and using a known method, the acid value of the target fat Predict when to threshold (when available).

Next, in step S11, the output unit 20 outputs and displays determination result data including the measured acid value of the target fat, the determination result, and the predicted usable time.
Specifically, as shown in Fig. 9, "acid value 2.1", the judgment result "○", and the prediction result "can be used until about ○ month ○○ day" are output and displayed on the display screen. do.

Finally, in step S12, a control unit (not shown) accepts a predetermined operation instruction from the user and determines whether or not to end the deterioration degree measurement of oil.
Specifically, when the measurement of the degree of deterioration of fats and oils is finished (step S12: Yes), the process of FIG. 10 is finished. On the other hand, when continuing to measure the deterioration degree of fats and oils (step S12: No), the process returns to step S2.

With the above configuration, it is possible to display a list of past results (contents of measurement results and judgment results) narrowed down for each oil and fat, or narrowed down within a specified period and display a list, so that the user can display past measurement results can be viewed efficiently.
Further, every time the degree of deterioration of the target oil is measured, the content of the measured result is automatically stored in the storage unit 10 . Therefore, the result list display unit 21 can display the list of the latest result contents on the display screen.

In addition, in the fats and oils deterioration degree measurement program shown in FIG. 10, it is preferable that the process of the result list display part 21 is performed after the process of the output part 20 in step S11. By doing so, the user can compare the results of the target fats and oils at the present time with the results of the past, and consider how to handle the fats and oils in the future.
Further, the processing of the result list display unit 21 may be executed before the processing of the threshold setting unit 11 in step S1 or before the processing of the threshold changing unit 12 in step S2. By doing so, when the user sets or changes the acid value threshold value, it is possible to check the result contents (history information) of the past target fats and oils in advance.
