Abstract

The invention discloses a processing method of an alcohol taste tea concentrated solution. The processing method comprises the following steps: 1), crushing and screening tea; 2), extracting effective components in the tea by using a countercurrent extraction column to obtain extract liquid A and extract liquid B; 3), centrifuging the extract liquid A and the extract liquid B at high speeds to obtain supernatant liquid A and supernatant liquid B; 4), concentrating the supernatant liquid B through a reverse osmosis membrane to obtain concentrated liquid B; 5), hydrolyzing the concentrated liquid B by using complex enzyme to obtain an enzymatic hydrolysate B; 6), mixing the enzymatic hydrolysate B with the supernatant liquid A, and seasoning to obtain tea concentrated liquid; 7), sterilizing and filling the tea concentrated liquid to obtain alcohol taste tea concentrated liquid or further spray drying or freeze drying the tea concentrated liquid to obtain instant tea powder. The tea concentrated liquid processed by the method has the characteristics of fresh and mellow taste, light in bitter taste and good flavor quality.

Description

technical field [0001] The invention belongs to the technical field of tea beverage processing methods, and in particular relates to a processing method of mellow tea concentrate. Background technique [0002] Tea is a healthy drink with various pharmacological effects and health care functions, and has always been popular among consumers. In the past two decades, my country's tea beverages have been in a stage of rapid development, with an average annual growth rate of more than 20%. In 2012, the production and sales volume exceeded 12 million tons. However, with the continuous improvement of national living standards, consumers have higher and higher requirements for the quality, safety and flavor quality of tea beverages. Tea extracts such as tea concentrates and instant tea powders were originally mainly used as intermediate raw materials for the production of liquid tea beverages or other tea foods, and have relatively low requirements for flavor quality. However, tea...
