| 摘 要： | 本文通过筛选实验,研究了一种复合型高效天然抗氧化剂,基本组成为茶多酚、大豆磷脂、抗坏血酸和大蒜提取物,其抗氧化作用随添加量的增加及使用温度的降低而增强,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其具有较强的还原性和清除自由基的能力以及组分间的协同增效作用. |
| 关 键 词： | 多不饱和脂肪酸 天然抗氧化剂 机理 |

| Abstract: | In this paper, a efficient natural mixed antioxidant was prepared through screening experiment. It was composed of tea polyphenols, soybean phospholipids, ascorbic acid and garlic extract. Its antioxidative effect could be raised with the increase of dose and the decrease of temperature and was obviously better than those 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 is due to the good ability to reduce oxides and eliminate free group and the cooperation and synergism among elements. |
| Keywords: | Polyunsaturated fatty acids Natural antioxidant Mechanism |
