Abstract:
      Frying is a common method of cooking food, but during the frying process, the quality of edible oil can deteriorate, posing a risk to human health. The factors affecting the deterioration of oil quality during the frying process were summarized, including the type of frying oil, frying time, frying temperature, and frying ingredients. The effects of the frying process on the generation of harmful substances in the oil, such as total polar compounds, trans fatty acids, acrylamide, 3-chloropropanol esters, and glycidyl esters were introduced. Measures such as categorized frying, blending of different types of edible oils, and the addition of antioxidants were proposed to improve the quality of frying oils. Attention should be paid to the factors causing quality deterioration during the use of frying oil, and appropriate measures should be adopted to enhance the frying stability of frying oil, thereby safeguarding consumer health and promoting the healthy development of frying food industry.
