A method of processing high-low bitter taste of tea catechins

The invention provides a processing method of high catechin beverage with low biter taste and belongs to the processing field of food. The processing method comprises the following steps of: 1) taking green broken tea, extracting three times continuously with water so as to obtain an extract liquid I, an extract liquid II and an extract liquid III; 2) coarsely filtering the extract liquid I, the extract liquid II and the liquid III so as to remove tea leaves; 3) respectively processing the extract liquid II and the extract liquid III by use of tannase so as to obtain the corresponding enzymolysis liquid I and enzymolysis liquid II; 4) mixing the extract liquid I, the enzymolysis liquid I and the enzymolysis liquid II to obtain a tea mixed liquid; 5) performing film separation process on the tea mixed liquid so as to obtain clarified tea water; 6) adding VcNa and cyclodextrin into the clarified tea water for mixing so as to obtain the tea beverage; and 7) filtering, sterilizing and bulking the tea beverage to obtain finished products. The tea beverage obtained by the processing method is a green-yellow tea beverage, wherein the content of catechin is more than or equal to 800mg/l; and the tea beverage belongs to a functional tea beverage with pure taste and crisp mouth feel and without obvious bitter taste.
