基于SPME-GC建立了茶油次级氧化产物中正己醛、2-反-己烯醛、辛醛、壬醛的定量分析方法,以指示物的加标回收率和变异系数(C.V)为指标选用壬醛作为茶油的次级氧化产物指示物,结合初级氧化产物(氢过氧化物)探讨了(+)-儿茶素在茶油乳化体系中乳化剂(吐温20)用量对其抗氧活性的影响。(+)-儿茶素在不同乳化剂用量的茶油乳化体系中的抗氧活性顺序依次为:对照 > 1% 吐温20 > 1.5% 吐温20 > 2.5% 吐温20 > 2% 吐温20。结果表明,在茶油乳化体系中(+)-儿茶素的抗氧活性随乳化剂用量的增多而降低。

The quantitative analysis of camellia oil secondary oxidation products hexanal, trans - 2 - hexenal, octanal and nonanal have been developed by SPME - GC. Nonanal was selected as the indicator of secondary oxidation products by the process of recovery and C.V. The effect of emulsifier dosage on the antioxidant activity of （＋）- catechin in camellia oil in water emulsion has been investigated by indicator of hydroperoxides and nonanal; the antioxidant activity of （＋）- catechin in individual emulsifier dosage of emulsion with the order of co...
