There is a high correlation between dielectric constant and deterioration of frying oils and thus the dielectric constant can be used to measure the quality changes of frying oils, which has the advantages such as fast detection, easy operation and food grade safety. The review described test principle of dielectric property on liquid and dielectric property of frying oils including correlation fitting model between TPC and dielectric constant. Three rapid test kits:FOS, FOM 310 and Testo 270 were evaluated with their structure, operation and data reliability. Then the main factors affecting the accuracy of detection were analyzed to be oil variety, cali-bration, suspended solids and operation. Finally, two future trends in this technology including specific optimi-zation for signal parameters and combination with data processing technique or infrared testing technique were prospected.
