维生素E抗油脂氧化的功能探讨

An Exploration on the Function of Vitamin E as Oil Antioxidant

抗氧化功能是维生素Ｅ的一种基本功能。维生素Ｅ特殊的化学结构与性质使得它既能抗油脂自动氧化，又具有一定的淬灭１Ｏ２的能力。本文根据目前公认的油脂氧化机理，就维生素Ｅ抗油脂氧化的机理与具体功能进行了探讨，并且介绍了一些常见油脂中的ＰＵＦＡ与维生素Ｅ的水平。

Antioxygenation is a general function of vitamin E. The particular chemical structure and property of vitamin E make it an oil autoxidation inhibiter and a singlet oxygen quencher. According to the universally accepted oil oxidation mechanism ,the oil antioxidation mechanism and concrete function of vitamin E are explored in this paper. Besides,the PUFA level and vitamin E level of some types of common oil and fat are introduced as well.
