【摘要】 采用氨基酸自动分析仪测定分析大红袍、水仙、肉桂、雀舌、金毛猴和矮脚乌龙等6个品种武夷岩茶的游离氨基酸组分,结果表明:6个品种武夷岩茶均含有17种氨基酸,氨基酸含量品种间差异显著,武夷岩茶的游离氨基酸总量为75.82~107.12 mg/g;其中含量较高的为谷氨酸、天冬氨酸和亮氨酸。武夷岩茶的氨基酸中含有各种人体必需氨基酸,且比例均衡;必需氨基酸总量占30.47%~40.46%,药用氨基酸含量丰富,占氨基酸总量的61.29%~63.90%;呈鲜味的氨基酸含量也占氨基酸总量的23.80%~28.63%,因此,武夷岩茶具有较高的营养价值和保健功能。更多还原

【Abstract】 The composition of free amino acids of Wuyi Rock Tea, which was made by cultivars Dahongpao,Shuixian, Rougui, Queshe, Jinmaohou and Aijiao-wulong, was analyzed in the study by using automatic amino acid analyzer. The results showed that 17 kinds of amino acids existed in the six cultivars, and the amino acid contents were extremely different. The total amount of free amino acids in the cultivars was 75.82~107.12 mg/g. In general, the contents of glutamic acid, aspartic acid and leucine were higher than other amino acid components in cultivars. Seved kinds of amino acids essential to human existed, which accounted for 30.47%~40.46% of the total. It was rich in medicinal amino acids, and the ratio accounted for 61.29%~63.90%, and the umami tasty amino acids accounted for 23.80%~28.63%. Based on the results, it was concluded that Wuyi Rock Tea had higher trophic and medicinal value.更多还原
