After cooking oil is heated at high temperature, harmful substances such as oxides, free fatty acids and total polar compounds will be produced. Therefore, countries have established regulations and standards for the content of oil oxides, free fatty acids and total polar compounds. Among them, in the regulations of Taiwan, the content of total polar compounds shall not exceed 25%.

In order to comply with regulatory requirements, various methods for detecting the total polar substance content of oil products have been developed. Generally speaking, people use column chromatography to measure the total polar substance content of oil products. However, the column chromatography method needs to send the oil sample to the laboratory for analysis with professional instruments, and it takes about 6 hours. Therefore, column chromatography is rather time-consuming. In addition, the total polar substance content can also be detected by using PTC total polarity test paper, but it still takes more than 30 to 40 minutes. In addition, both of the above two methods need to use the naked eye to identify and observe, so there is a possibility of visual error.

In addition, there is an edible oil polar compound detection instrument that can directly measure the total polar substances of edible oil, and requires several minutes of measurement time.
