油脂加工过程中氧化稳定性的研究进展

油脂是人体重要的储能物质，营养价值丰富，在日常生活中不可或缺，但其极易氧化酸败，生成有毒有害物质，造成其营养价值大幅降低。以常见油脂的加工工艺（包括提取、精炼和成品油后加工）为主线，着重介绍各加工工艺对油脂氧化稳定性的影响，并针对油脂氧化过程中存在的问题提出今后可改进的方向。

Advance in oxidative stability of oil during processing

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.
