采用云南大叶种茶树鲜叶为原料,应用专利茶鲜叶厌氧处理设备,进行真空充氮厌氧处理,再加工成绿茶。结果表明:经厌氧处理制成绿茶的γ-氨基丁酸(GABA)质量分数增加。其中,充氮厌氧处理6h以上的绿茶均达到了GABA茶叶标准。结果表明,云南大叶种茶树可以加工为GABA绿茶,为云南GABA茶叶的开发提供了实验依据,为丰富云南茶叶产品种类奠定了基础。
The use of fresh leaves of Yunnan big leaf tea as raw material, the application of fresh tea leaves anaerobic treatment equipment, vacuum anaerobic treatment of nitrogen, and then processed into green tea. The results showed that the mass fraction of γ-aminobutyric acid (GABA) produced by anaerobic treatment increased. Among them, green tea anaerobic treatment of 6h or more reached the GABA tea standard. The results showed that the big leaves of Yunnan tea can be processed into GABA green tea, provided the experimental basis for the development of Yunnan GABA tea, and laid the foundation for enriching Yunnan tea products.
