摘要: 研究以茶多酚、大豆磷脂、抗坏血酸和大蒜提取物为原料,探讨了四者复配物在不饱和脂肪中的抗氧化作用。结果表明,其抗氧化效果明显优于常用的BHA、BHT、PG及天然混合生育酚、茶多酚,并能在一定程度上使已氧化为过氧化物的多不饱和脂肪酸复原。其作用机理主要是由于具有较强的还原性和清除自由基的能力,并表现出组分间的协同效应。

关键词: 多不饱和脂肪酸, 天然抗氧化剂, 机理

Abstract: In this paper,the antioxidation effect of a complex natural antioxidant on unsaturated lipids was studied.It was composed of tea polyphenols,soybean phospholipids,ascorbic acid and garlic extract.Its antioxidative effect was obviously better than that of BHA,BHT,PG,mixed tocopherols and tea polyphenols.Moreover,it could recover polyunsaturated fatty acids from their peroxides to a certain degree.Its mechanism was analyzed as the good ability to reduce oxides,to extinguish free radicals and to enhance the synergic effects among elements.
