Problems solved by technology

The general method of extracting tea is as follows: the ratio of dry tea to water is about 1:50, the water temperature is 20-100°C, and the time is 1-30 minutes; considering the quality of the product, the existing various tea-extracting methods are Pay attention to the stability of the product during the shelf life, but there are no better modification and enhancement measures for the aroma of tea beverages and reducing the bitterness of tea beverages, so it is difficult to produce high-quality tea beverages, especially pure tea beverages

Abstract

The invention provides a preparation method for a green tea drink. The preparation method includes the following steps: 1) pre-processing tea leaves, picking the fresh tea leaves to performing impurity removing, then performing spreading until the water content of the fresh tea leaves is 70-80%, performing green-killing on the fresh tea leaves, performing natural cooling to room temperature, and obtaining green-killed leaves; 2) performing extraction, performing liquid nitrogen treatment on the green-killed leaves, then immediately transferring the green-killed leaves into a crucible holding hot water with 90-100 DEG C, performing stirring for 5-10s until the green-killed leaves completely melted, performing grinding, water temperature being maintained at 90-100 DEG C during grinding, obtaining juice through grinding, and obtaining supernatant through low temperature centrifugation; 3) filtering the supernatant by using a molecular sieve to obtain a filtered solution; and 4) adding a blending agent into the filtered solution to perform blending, performing sterilization and drying so as to obtain the green tea drink. The green tea drink prepared through the method can reduce bittertaste and preserve tea fragrance, and is clear and bright.

Description

technical field [0001] The invention belongs to the field of tea, and in particular relates to a preparation method of green tea beverage. Background technique [0002] Tea can be roughly divided into three categories; green tea (unfermented tea), black tea (fermented tea), and oolong tea (semi-fermented tea). They are all derived from the tea tree (scientific name: Camellia sinensis) belonging to the genus Theea and Theaceae, and depending on the processing method of the tea, mainly the difference in the degree of fermentation, the teas with excellent aroma and taste are produced completely different. [0003] Green tea (Green Tea) is one of the main teas in China. It refers to the beverage made from the new leaves or buds of the tea tree without fermentation, after greening, shaping, and drying. The color of its finished product and the tea soup after brewing mostly preserve the green style of fresh tea leaves. Drinking green tea regularly can prevent cancer, reduce fat ...
