A method of extracting the essence of tea includes the following steps: placing a yeast species capable of fermenting tea leaves and tea leaves into a sealed container controlling the ambient temperature in the sealed container within a temperature range most suitable for inducing the glycation effect on the yeast species, so as to enable the yeast to start the fermentation for the tea leaves transferring the material in the sealed container to a reverse osmosis filtration system for filtration at the time of generating the mannanase in the sealed container and dehydrating the pale yellow liquid obtained after filtration to produce a dried tea essence powder.一種茶葉精華的萃取方法包含有下列的步驟:將可使茶葉發酵之一酵母菌種與茶葉加入一密封容器中;控制該密封容器中的環境溫度該酵母菌種進行醣化作用之一最適溫度範圍中,以使得該酵母菌對茶葉開始進行發酵;當該密封容器中產生甘露聚醣時,將容器內的物質轉移至一逆滲透過濾系統中來進行過濾;以及對過濾後所得到的淡黃色液體進行脫水來產生乾燥的茶葉精華粉末。S100~S130‧‧‧步驟
