To improve the quality of summer-autumn tea, the fermentation of summer-autumn tea was investigated by using Eurotium cristatum. The contents of tea polyphenols, total free amino acids, total flavonoids, water leachate, and sensory scores of summer-autumn tea were used as the indicators for the one-way experiment, and four factors and three levels were selected for orthogonal experiments to optimize the fermentation process. The volatile compounds of fermented summer-autumn tea under the optimal process were analyzed by gas chromatography-mass spectrometry (GC-MS) technology. The results showed that the optimal fermentation process was 30% water content, 15% inoculum of Eurotium cristatum, fermentation time of 9 d, and fermentation temperature of 30 ℃, and the water leachate content of summer-autumn tea processed under these conditions was significantly increased by 22.51% (P |
