Abstract

The invention provides a preparation method of a sweet potato stem tip and green tea beverage. The preparation method comprises the following steps: (1) taking fresh tea leaves and sweet potato stem tips and removing impurities, adopting a roller fixation machine for fixation for several times, wherein materials are added when the temperature in a roller is 100 to 120 DEG C; (2) freezing the fixated tea leaves and sweet potato stem tips by using liquid nitrogen and smashing immediately after the freezing treatment to obtain a smashed raw material mixture; (3) immediately mixing the smashed raw material mixture with a certain amount of hot water with the temperature of 80 to 100 DEG C; (4) smashing the smashed raw material mixture again; (5) removing tea residue components from a water extract, wherein the temperature is controlled to be 80 to 100 DEG C in the whole extraction process; (6) drying the water extract to a semi-solid or solid state. The beverage prepared by the preparation method provided by the invention is bright, green and clean in liquor color, and the taste is mellow and sweet after taste, and the stringent taste is avoided.

Description

technical field [0001] The invention belongs to the technical field of tea beverages, and in particular relates to a preparation method of tea and potato tip green tea beverages.
