摘要
以晒青茶为原料,接种专利菌株近平滑假丝酵母( Candida parapsilosis ) GPT-5-11(专利号:201010182948.5)发酵普洱茶。结果表明,接种菌株的普洱茶样品GABA含量为0.3052~1.5332 mg/g,显著高于对照0.0628~0.1047 mg/g,其中灭菌每翻接种液态菌的样品 GABA含量最高,为1.5332 mg/g,达到 GABA茶的标准。同时,接种该菌株进行发酵后,发酵茶样中的主要功能成分含量均较自然发酵茶叶中的含量高,具有传统普洱茶的品质风味,且在香气和滋味方面有自身的特点,滋味醇和、厚滑,香气纯正略带乳香。
Sun-dried green tea was fermented by inoculation of Candida parapsilosis GPT-5-11. HPLC analysis showed that the contents of GABA in fermented tea samples inoculated GPT-5-11 yeast were 0.3052~1.5332 mg/g, and significantly higher than that in control fermented tea samples. The content of GABA in fermented sample No. 7 was 1.5332 mg/g, and it meets the Japanese standards of GABA tea. Chemical analysis and sensory evaluation showed that the content of chemical components of samples fermented with GPT-5-11 yeast were higher than those of the controls, and have special features in aroma and color as well as the characteristics of traditional pu-erh tea.
