对不同富硒茶油的天然抗氧化活性成分及其氧化稳定性指标值进行了分析研究。结果表明:富硒茶油天然抗氧化活性成分的含量多数比普通茶油高,而其过氧化值,酸值和共轭二烯值均比普通茶油低,说明其氧化稳定性较好,这是因为硒促进了茶油中的天然抗氧化活性成分合成积累,同时硒也对自由基产生富集加合作用,两者共同作用,使其氧化稳定性提高。
We analyzed the natural antioxidant activity composition of Se-enriched camellia oil and its oxidation stability index. The results showed that natural antioxidant ingredients of Se-enriched camellia oil were higher than ordinary camellia oil. And the peroxide value,acid value and conjugated diene value were lower than ordinary camellia oil. The oxidation stability of Se-enriched camellia oil is better. The reason may be that the selenium promotes the synthesis of natural antioxidant ingredients. So the oxidation stability of Se-enriched camellia oil got improved.
