However, the oxidation, hydrolysis, and polymerization will occur during frying. These side reactions produce harmful compounds and affect the quality of frying oil and fried foods. The key of frying lies in the food frying process management. This paper reviews 6 points of the good manufacturing practice (GMP) in food frying. The quality of frying oils and fried foods is ensured by selecting good frying oils (relatively high saturated degree oils rich in antioxidants) and special frying instruments, controlling frying temperature (no more than 190 ), cleaning up the instruments (once daily), adding fresh oils and analyzing oil quality periodically (determine the polar compound during frying). The nutrition and security can be ensured according to GMP frying operations, and the frying life of oil can be extended. The resources will be saved if the standard procedures are followed. The results can provide a reference for the drafting of standards about frying oil and related research.
