Fat and oil deterioration degree detection device, fat and oil deterioration degree detection system, fat and oil deterioration degree detection method, and fat and oil deterioration degree detection program

A fat and oil deterioration degree detection device for detecting a deterioration degree of a fat and oil, the device comprising:

• a storage section configured to retain a correlation between a first deterioration indicator and a second deterioration indicator, the first deterioration indicator being a deterioration indicator of the fat and oil and defined based on a substance produced by heating the fat and oil, and the second deterioration indicator being a deterioration indicator of the fat and oil other than the first deterioration indicator;
• a data acquisition section configured to acquire a measured value of the first deterioration indicator;
• a deterioration indicator calculation section configured to calculate the second deterioration indicator based on the measured value of the first deterioration indicator acquired by the data acquisition section and the correlation stored in the storage section;
• and
• a detection result output section configured to output the second deterioration indicator calculated by the deterioration indicator calculation section as a result of detection of the deterioration degree.
