摘要
对咖啡碱(CAF)和牛血清白蛋白(BSA)在双酯型茶黄素形成中的影响进行了研究分析。结果表明,咖啡碱和牛血清白蛋白对TFDG的形成均有明显的抑制作用,而且相同条件下,牛血清白蛋白和咖啡碱表现出相似的抑制作用。当牛血清蛋白与咖啡碱同在一个化学氧化反应体系中时,表现出随浓度不同而呈现复杂的竞争或协同作用。
The impact of caffeine(CAF) and bovine serum albumin (BSA) on the formation of theaflavin-3,3'-digallate was compared and analyzed. The results on chemical oxidation showed that CAF and BSA had obvious inhibitory action on the formation of Theaflavin-3,3'-digallate. Under identical condition, BSA showed the same inhibitory action as CAF. When BSA and CAF were existing in the same chemical oxidation system, the complicated competition and cooperation were investigated.
