摘要: 采用3因素3水平正交试验设计,研究厌氧处理的气体种类、处理时间和处理温度对茶叶γ-氨基丁酸含量及其品质成分的影响。结果表明:影响茶叶中γ-氨基丁酸含量的主要因素是处理时间,其次是气体种类,处理温度没有显著影响。综合γ-氨基丁酸含量和各项茶叶品质成分指标,确定茶鲜叶厌氧处理的最佳条件为:真空、25℃、8h。

Abstract: Effects of the kind of gas, the duration and the temperature on the γ- amino butyric acid (GABA) content and thequality components of tea leaf under anaerobic treatment were investigated by the orthogonal design. The result showed that theamount of GABA in tea leaf under anaerobic conditions was mainly affecteds by the duration, followed by the kind of gas, butnot influenced by the temperature. Considering GABA content and quality components of tea leaf, the optimum conditions ofanaerobic treatment on fresh tea leaf were determined as follows: Vacuum , 25℃, 8h.
