Abstract

The invention relates to a processing method of tea leaves. The method comprises the following steps: (a) fresh leaf spreading: putting picked fresh large-leaf green tea into a greenhouse of which the temperature is 3-6 DEG C and the humidity is 30-40% for spreading until the moisture content of the leaves is 75-80%; (b) fixation: putting the spread leaves into a rotary drum frying pan of 160-165 DEG C for fixation until the moisture content of the fixed leaves is 60-65% and putting the leaves into the greenhouse of which the temperature is 30-35 DEG C and the humidity is 30-40% for cooling until the moisture content of the cooled leaves is 45-50%; (c) kneading: kneading the cooled leaves at 55-60 DEG C by adopting kneading equipment; and (d) drying: drying the kneaded tea leaves to obtain dry leaves of which the moisture content is 5-9%. The processing method has the beneficial effects that the obtained tea leaves are sweet, mellow and thick in taste, light in bitter taste and high in fragrance.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a tea processing method. Background technique [0002] The formation of excellent quality of tea mainly depends on the quality of fresh leaves and processing technology, which can be judged by sensory evaluation of appearance, smelling aroma, looking at soup color, and tasting. [0003] Traditionally processed Yunnan big-leaf green tea is generally obtained by cooling the fresh tea leaves after picking, kneading, shaping, and drying, which has the disadvantages of low fragrance and bitter taste. In order to solve this shortcoming, raw materials such as jasmine flower and glutinous rice are often added when kneading to improve its mouthfeel, and also change the mouthfeel of the tea itself at the same time. Corresponding studies have also shown that Yunnan big-leaf green tea contains more indoles and polyphenols, resulting in a strong sense of bitterness. For this reason,...
