摘要: 为改善二氢杨梅素的脂溶性,采用化学修饰法制备了二氢杨梅素癸酸酯。考察该产品的溶解性及不同酯化物对猪油的抗氧化活性。结果表明:通过癸酰氯修饰的二氢杨梅素在油溶性基质中具有良好的分散稳定性,当酯化度为3时,其对猪油的抗氧化能力最强,在相同质量分数时二氢杨梅素癸酸酯的抗氧化活性优于二氢杨梅素和BHT,0.05%二氢杨梅素癸酸酯的抗氧化性能与TBHQ接近。

Abstract: In order to improve the solubility of dihydromyricetin in oils, liposoluble dihydromyricetins with different degrees of esterification were synthesized by chemical modification with decanoyl chloride and their solubility and antioxidant property in lard were examined. The results showed that the decanoyl chloride-modified dihydromyricetin had good dispersity in oils and the strongest antioxidant ability when the degree of esterification was 3. At the same concentrations, the antioxidant activity of liposoluble dihydromyricetin with a degree of esterification of 3 was higher than that of dihydromyricetin and BHT. The antioxidant activity of the liposoluble dihydromyricetin at the dosage of 0.05% was similar to that of 0.02% TBHQ.

Key words: dihydromyricetin, chemical modification, liposolubility, antioxidant properties
