摘要:

在花生油中添加天然芦荟蒽醌和路边青多酚复配物,考查紫外光、温度、KClO3 和复配物配比对花生油过氧化值的影响。实验结果表明:分别用紫外光照射和90℃温度加热反应6h,花生油中添加复配物的过氧化值比空白分别小22.55% 和23.67%,比加BHT 分别小8.43% 和7.57%;用2ml 0.1mol/L KClO3 氧化6h,花生油中添加复配物的过氧化值比空白小22.85%,比加BHT 小7.00%。花生油中添加2:1(V/V)复配物的羟基自由基清除率是加BHT 的1.06 倍,是空白实验的4.4 倍。

Abstract:

Anthraquinone-polyphenol complexes were prepared from anthraquinone from Aloe leaves and polyphenol from Herba gei with different mixing ratios. The influence of UV-light, temperature, KClO3 and mixing ratio on peroxide value (PV) of peanut oil with the addition of the complex were investigated. After 6 h treatments of UV-light irradiation and heating at 90 ℃, significant decreases were observed in the PV of peanut oil with the addition of the complex in comparison with the blank (without the addition of the complex) by 22.55% and 23.67% and peanut oil with the addition of BHT by 8.43% and 7.57%, respectively. After 6 h oxidation of 0.1 mol/L KClO3 (2 ml), the PV of peanut oil with the addition of the complex was reduced in comparison with the blank by 22.85% and peanut oil with the addition of BHT 7.00%. The hydroxyl free radical scavenging activity of peanut oil with the addition of the complex prepared with the mixing ratio of 2:1 (V/V) was 1.06 and 4.4 times of that of peanut oil with the addition of BHT and the blank, respectively.

Key words: anthraquinone, polyphenol, antioxidant, peanut oil
