红茶中4种主要茶黄素单体:
2、茶黄素-3-没食子酸酯(TF3G):Theaflavin 3-O-gallate
3、茶黄素-3′-没食子酸酯(TF3′G):Theaflavin 3'-O-gallate
4、茶黄素双没食子酸酯(TFDG):Theaflavin 3,3'-di-O-gallate
茶黄素介绍:
茶黄素类化合物是红茶中的主要成分,对红茶的色香味及品质起着决定性的作用,主要包括茶黄素(TF)、茶黄素-3-没食子酸酯(TF3G)、茶黄素-3′-没食子酸酯(TF3′G)和茶黄素双没食子酸酯(TFDG)等4种主要成分,是茶叶中儿茶素类物质经发酵氧化而形成的一种天然色素,被誉为茶叶中的脑黄金 . 红茶在加工过程中发生了以茶多酚酶促氧化为中心的化学反应,鲜叶中的化学成分变化较大,茶多酚减少90%以上,产生了茶黄素 (Theaflavin )、 茶红素 等
