硒与老鹰茶黄酮复配对山茶油的抗氧化效果Antioxidant effect of selenium combined with hawk tea total flavonoids on oil-tea camellia seed oil

Abstract

为了促进天然抗氧化剂的开发，以过氧化值为指标，以硒代蛋氨酸、甲基硒代半胱氨酸、亚硒酸钠和老鹰茶黄酮（HTTF）为研究对象，采用Schaal烘箱法对比单独和复配使用对山茶油的抗氧化效果。结果表明：硒代蛋氨酸、甲基硒代半胱氨酸和亚硒酸钠对山茶油均有抗氧化效果，且加入量越高，抗氧化效果越好；硒代蛋氨酸和亚硒酸钠与HTTF复配对山茶油的抗氧化效果均优于各单一组分，而甲基硒代半胱氨酸与HTTF复配对山茶油的抗氧化效果优于HTTF，但逊于甲基硒代半胱氨酸；硒代蛋氨酸、甲基硒代半胱氨酸、亚硒酸钠和HTTF单独使用和复配使用对山茶油的抗氧化效果均弱于TBHQ。综上，不同的硒与HTTF复配对山茶油的抗氧化效果不同。 In order to promote the development of natural antioxidants, the peroxide value was used as an indicator, the antioxidant effects on oil-tea camellia seed oil of single selenium antioxidant (selenomethionine, methylselenocysteine, sodium selenite) and hawk tea total flavonoids (HTTF) and their combination were determined by Schaal oven method. The results showed that selenomethionine, methylselenocysteine and sodium selenite all had antioxidant effects on oil-tea camellia seed oil, and the higher the amount added, the better the antioxidant effect. The antioxidant effects of selenomethionine and sodium selenite in combination with HTTF on oil-tea camellia seed oil were better than those of the individual components, whereas the antioxidant effect of methylselenocysteine and HTTF in combination was better than that of HTTF but inferior to those of methylselenocysteine. The antioxidant effects of selenomethionine, methyl selenocysteine, sodium selenite and HTTF on oil-tea camellia seed oil were weaker than those of TBHQ when used alone or in combination. In conclusion, the antioxidant effects of different selenium combined with HTTF on oil-tea camellia seed oil are different.
