采用Rancimat比较不同添加状态下茶油多酚标品没食子酸、槲皮素、儿茶素以及油茶副产物叶子、种子、茶油提取物对茶油氧化稳定性的影响,在茶油中添加不同质量浓度的单一和复配抗氧化剂,分别测定其诱导时间并考察其抗氧化性能。结果表明:油茶副产物提取物和多酚标品都有较好抗氧化效果,添加标品时固体状比液体状试验重复率高,浓度为150 mg/kg时,单一抗氧化剂抗氧化性能依次为没食子酸、叶子提取物、槲皮素、种子提取物、茶油提取物、儿茶素;当多酚进行两两复配时,150 mg/kg没食子酸和儿茶素复配物的抗氧化性能最高,三三复配时,100 mg/kg没食子酸、儿茶素和槲皮素混合物效果最好。

The anti-oxidation of Gallic acid, quercetin, catechin of dif- ferent states and bio-phenol extracted from leaves, seeds, oil in camellia was studied by Rancimat method. With adding different con- centrations of single antioxidant and different rations of antioxidant combination into camellia oil, the antioxidant effect was determined by using induction time. The result showed that both of the extracts and antioxidants contained antioxidant activity, and the antioxidants had a higher rei .on rate in solid than in liquid, at 150 mg/kg, the anti-oxidation of single antioxidant listed descending ...
