摘　　要：采用分子修饰法制备了豆油脂肪酸酐修饰的茶多酚,通过红外光谱对分子修饰的茶多酚进行了结构表征。将修饰后的茶多酚作为油脂的抗氧化剂,添加到豆油中,考察其溶解性及抗氧化性能。结果表明,有机基团修饰的茶多酚具有优良的分散性,可提高豆油的抗氧化性能。在相同浓度时,豆油脂肪酸酐修饰的茶多酚抗氧化活性优于茶多酚和BHT。Bean oil acid radical capped tea polyphenols were prepared using modification method. The structure of the prepared product was characterized by infrared spectroscopy. The solubility and antioxidafion properties of the product as additive in oils were examined. The results showed that the prepared product had good dispersity in oils and could increase antioxidation activity. The antioxidation activity of the modified tea polyphenols was better than the original tea polyphenols and BHT when adding the same amount in oils.
