Embodiment 1
[0019] Take 500 grams of fresh tea leaves and wither until the water content is 50-70%. The withered fresh leaves are vacuum-filled with nitrogen for 3 hours, then cooled at room temperature and aerobic for 2 hours. After the enrichment, the GABA content in the tea leaves reaches 1.5mg / g; add 2500ml of deionized water to the enriched fresh tea leaves, crush them, extract for 15min, and filter to obtain 2400ml of tea soup after extraction, add 50 grams of husks to the tea soup The polysaccharide was stirred and clarified for 30 minutes, and centrifuged at 7000 rpm to obtain clarified tea soup. Mix the tea soup and white wine at a volume ratio of 4:1 to obtain a soft and refreshing high-quality GABA-rich tea wine with a clear and transparent color, a compound aroma of green tea and wine. Liquor is liquor at 45°. The GABA content of gained tea wine is 0.25g / L, is clear and transparent in color and luster, has the compound aroma of green tea and wine, soft and refreshing high qua...
Embodiment 2
[0021] Take 500 grams of fresh tea leaves and wither until the water content is 50-70%. The withered fresh leaves are vacuum-filled with nitrogen for 3 hours, then cooled at room temperature and aerobic for 2 hours. After the enrichment, the GABA content in the tea leaves reaches 1.8mg / g; add 2500ml deionized water to the enriched fresh tea leaves, crush them, extract for 30min, and filter to obtain 2400ml tea soup after extraction, add 50 grams of husks to the tea soup The polysaccharide was stirred and clarified for 30 minutes, and centrifuged at 7000 rpm to obtain clarified tea soup. Mix the tea soup and white wine at a volume ratio of 4:1 to obtain a soft and refreshing high-quality GABA-rich tea wine with a clear and transparent color, a compound aroma of green tea and wine. Liquor is liquor at 45°. The GABA content of gained tea wine is 0.3g / L, is clear and transparent in color and luster, has the compound fragrance of green tea and wine, soft and refreshing high qualit...
Embodiment 3
[0023] Take 500 grams of fresh tea leaves and wither until the water content is 50-70%. The withered fresh leaves are vacuum-filled with nitrogen for 3 hours, then cooled at room temperature and aerobic for 2 hours. After enrichment, the GABA content in the tea leaves reaches 1.8mg / g; add 2500ml of deionized water to the enriched fresh tea leaves, crush them, extract for 30min (should be a specific value), and filter to obtain 2400ml of tea soup after extraction. Add 50 grams of chitosan to the tea soup, stir and clarify for 30 minutes, and centrifuge at 10,000 rpm to obtain clarified tea soup. Mix the tea soup and white wine at a volume ratio of 4:1 to obtain a soft and refreshing high-quality GABA-rich tea wine with a clear and transparent color, a compound aroma of green tea and wine. Liquor is 52°, the GABA content of the obtained tea wine is 0.3g / L, it is clear and transparent in color, has the compound aroma of green tea and wine, soft and refreshing high quality, the ph...
