As an important energy storage material of human body, oil is rich in nutrition,and it is indispensable in modern life. However, oil is very easy to be oxidized and to generate hazardous substances, resulting in sharp reduction of nutritional value. The effects of processing technologies on oxidative stability index (OSI) of oil were introduced based on the common oil processing technologies (including extraction, refining and post processing of refined oil), and the improvement direction aimed at the problem existed in the process of oil oxidation was put forward for future. |
