The invention provides an oleic acid value detection device and method, and relates to the technical field of acid value detection. The oleic acid value detection device comprises a shell, a host unit, a display unit and an interdigital electrode sensor; the host unit is installed in the shell, the display unit is arranged on one side of the shell, and the interdigital electrode sensor is installed at one end of the shell; and the host unit is respectively connected with the display unit and the interdigital electrode sensor. According to the oleic acid value detection device and the oleic acid value detection method provided by the invention, the dielectric constant information of the oil is obtained through the interdigital electrode sensor, then the acid value can be directly obtained after data processing and analysis, and the acid value is displayed; during detection, a final acid value measurement result can be obtained only by inserting the device into oil for a moment, the detection is rapid and accurate, and the cost is relatively low.
Description
technical field [0001] The invention relates to the technical field of acid value detection, in particular to an oil acid value detection device and detection method for frying oil. Background technique [0002] For the processing of food, it is usually prepared by frying with frying oil. During the frying process, the frying oil is heated to about 150°C to 180°C. At this temperature, the frying oil undergoes aging, such as being oxidized by oxygen in the air. 1. High temperature will produce many chemical decomposition products, which not only affect the taste of food, but also affect the health of the body. In order to determine the quality of frying oil during frying, it is usually necessary to measure the acid value and polar components of frying oil, which is a measure of the degree of thermal-oxidative decomposition of frying oil. [0003] Existing detection methods for the acid value of frying oil include acid-base titration and test paper detection. The acid-base ti...
