Abstract

The invention provides a preparation method of fruit green tea drink powder. The method comprises the following steps: (1) pretreatment of tea leaves: picking fresh tea leaves before Qingming Festival, removing impurities, conducting spreading treatment, then putting the fresh tea leaves and bamboo seeds in a green-killing machine for green killing treatment at 100-120 DEG C, conducting naturallyspreading and cooling down to room temperature, removing bamboo seeds, and obtaining green-killing leaves; (2) extraction treatment: grinding the green-killing leaves into juice, then performing low-temperature centrifugation, and obtaining a centrifugal solution; (3) filtering the centrifugal solution with a molecular sieve to obtain a filtered solution, and adding fruit powder to the filtered solution to perform stirring and mixing; and (4) adding a blending agent to the mixed solution to conduct blending, then performing sterilization and drying, and obtaining the fruit green tea drink powder. The fruit green tea drink powder prepared by the method can reduce the bitterness, is clarified and translucent, and retains the nutritional components of fruit and the aroma of fruit tea.

Description

technical field [0001] The invention belongs to the field of tea, and in particular relates to a preparation method of fruit green tea drink powder. Background technique [0002] 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 and lose weight, and can also reduce the damage of nicotine to smokers. Green tea is made without fermentation, which retains the natural substances of fresh leaves, and contains more nutrients such as tea polyphenols, catechins, chlorophyll, caffeine, amino acids, and vitamins. These natural nutrients in green tea have special effects on anti-aging, anti-cancer, anti-cancer, sterilization, anti-inflammatory, etc., which are beyond the ...
