Description

technical field [0001] The invention relates to the technical field of deep processing of tea, in particular to a green tea beverage and a preparation method thereof. Background technique [0002] In recent years, natural, healthy, fast and convenient tea drinks have grown rapidly at home and abroad, becoming the most dynamic and potential drinks. Traditional green tea is made from the young buds and leaves of tea trees, which are processed through processes such as killing greens, rolling and drying. There are a variety of active and effective substances in fresh tea leaves. After the tea leaves are processed into dry tea, the activities of many effective substances are destroyed and reduced. Therefore adopt the fresh tea leaf as raw material to directly process the beverage that has different mouthfeel and better health effect from traditional tea beverage. The current tea beverages are all made of finished tea leaves, which are extracted, clarified, blended, sterilized,...
