摘要
Abstract
Enrichment effect of γ-aminobutyric acid (GABA) in tea by vacuum treatment and extrogenous sodium glutamate was investigated. The result indicated that the GABA content reached 1.325 mg/ g(DW),by vacuum treatment of the tea fresh leaf for 8 h, 6.7 times as high as untreated tea; when tea leaf first soaked in 2.5 % sodium glutamate solution for 4h, then treated for 8h by vacuum, the GABA in tea obtains further enrichment, and the content reached to 2.501 mg/g, 12.6 times as high as untreated tea.关键词
