Embodiment Construction

[0020] Fuzhuan brick tea is prepared through the following steps:

[0021] (1) Rapid aging of raw materials: Use high-temperature steam to heat raw tea raw materials, increase the water content of raw tea to 16%, control the temperature of the tea pile at 60°C, and age for 36 hours. Turn the pile once during the period, and then naturally age for 3 months before use In the processing of Fuzhuan tea;

[0022] (2) Preparation of golden flower fungus powder: inoculate three kinds of purified S. coronis into PDB medium supplemented with 10% Fucha juice, and culture at 28°C for 5 days to obtain OD 600 The spore suspension with a value of 0.6 was then inoculated in the bran culture medium according to the mass ratio of 10%, and after 4 days of constant temperature cultivation at 28°C, the bran koji was obtained, which was crushed through a 100-mesh sieve to obtain the golden flower fungus powder;

[0023] (3) Screening and blending: blend the aged black mao tea or sun-dried green m...

Abstract

The present invention discloses a processing method of Fuzhuan tea using summer and autumn raw tea. The Fuzhuan tea is prepared by the following steps: raw material rapid aging, golden flower fungus (eurotium cristatum) powder preparing, sieving and blending, steaming and pile-fermenting, humidifying and steaming, inoculating, pressing and shaping, regulating and flower-shape fungus forming, drying, etc. By controlling tea leaves and environment temperature and humidity, and applying microbial inoculation technology, raw material aging is accelerated, growth and reproduction of the eurotium cristatum are induced and regulated, product processing cycle is shortened, the growth of the "golden flowers" is promoted, infectious microbe contamination is reduced, and the stability of the product quality is improved.

Description

technical field [0001] The invention relates to a processing method of Fu brick tea, which belongs to the field of tea processing. Background technique [0002] Fuzhuan tea is currently the dark tea product with the most complicated processing technology, the longest production cycle and the most unique craftsmanship among all teas. Among them, the "golden flower" (scientific name: Saccharomyces coronatus) determines the quality of Fuzhuan tea. core indicators. Traditional Fuzhuan tea has to be stored for at least 2 years for raw tea raw materials, and can only be used in the processing of Fuzhuan tea after the transformation of the contained substances, and the flowering time is longer, the "golden flower" particles are smaller, and the quality of tea bricks is unstable , researchers have done a lot of research. At present, most of the researches are to increase the degree of alcoholization of Fuzhuan tea by adjusting the temperature and humidity to accelerate the alcohol...
