乌龙型灵芝发酵茶的Ames试验及其品质特征分析

Ames test and quality evaluation of Ganoderma lucidum fermented Oolong tea

对用乌龙茶制成的乌龙型灵芝发酵茶进行Ames试验,以进一步测定乌龙型灵芝发酵茶的食品安全性,并与乌龙茶生化成分、感官审评进行比较.结果表明,乌龙型灵芝发酵茶对TA97、TA98、TA100和TA1024株试验菌株无诱导致畸变作用.生化成分分析表明:乌龙型灵芝发酵茶的水浸出物、粗蛋白、咖啡碱、多糖、总氨基酸、必需氨基酸和支链氨基酸的含量比乌龙茶高13%、21%、16%、78%、110%、131%和157%;乌龙型灵芝发酵茶的茶多酚含量比乌龙茶低59%.感官评审表明,乌龙型灵芝发酵茶的品质特征明显优于乌龙茶.
