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
