Embodiment 1

[0051] Embodiment 1: Separation and purification of Flos Chinensis:

[0052] The finished sample of Xiangyi brand Fuzhuan brick tea was pulverized with a plant micro pulverizer, sieved with 200 mesh, dried at 65°C for 2 hours, weighed 1g of the sample, fixed to a volume of 10ml, and prepared a concentration of 10 -1 、10 -2 、10 -3 、10 -4 、10 -5 Each 10mL, take 10 -3 、10 -4 、10 -5 Spread 0.0.5mL of each of the three gradients on the PDA plate added with 10% tea juice, blow dry on the ultra-clean table, incubate at 28°C upside down for 3 days, pick the golden yellow dominant colony, and draw a line to the PDA plate added with 10% tea juice On the plate, continue to culture under the same conditions until purification.

[0053] The isolated and purified golden flower colonies are shown in the appendix figure 1 .

Embodiment 2

[0054] Embodiment 2: the spore suspension preparation of golden flower:

[0055] Pick the purified golden flower colony, inoculate it into the PDA liquid medium with 10% tea juice, 20% sucrose, and 10% NaCl, culture it statically at 28°C for 2 days, then raise the temperature to 30-32°C for 7- After 10 days, the disperse conidia were cultured with shaking at 280 rpm, filtered with double-layer gauze, and the OD value measured by a 722-type spectrophotometer was 0.6-0.8, which was the usable golden flower spore suspension.

[0056] The results of the spore suspension culture of Jinhua are attached figure 2 .

Embodiment 3

[0057] Embodiment 3: Verification of green tea loose tea blooming:

[0058] Take respectively 1Kg of two kinds of green teas of different brands on the market, and carry out loose tea fermentation according to steps 2-8 in the specific embodiment.

[0059] Green tea loose tea flowering results see attached image 3 , Figure 4 .

Abstract

The invention provides a preparation process of fungus-grown loosened green tea, which comprises the steps of: 1, purifying and separating eurotium cristatum; 2, preparing an eurotium cristatum spore suspension and determining the concentration thereof; 3, processing a green tea sample; 4, adding the eurotium cristatum suspension; 5, drying the tea, 6, controlling the humidity and temperature forfungus growing; 7, ageing and drying the fungus-grown loosened green tea; and 8, storing the fungus-grown loosened green tea. The invention can realize the fungus growing of the green tea by inoculating by using the golden flower fungus in Fuzhuan tea in a short period, and golden flower is generally flourish, bright and yellow in color, and large in particles, thus the fungus-grown loosened green tea inherits the impressions of the traditional green tea and can be endowed with the characteristics of the Fuzhuan tea, and the internal quality and the additional value of the green tea are improved.

Description

Technical field: [0001] The invention relates to the technical field of agricultural product processing, in particular to a process for preparing traditional green tea through post-fermentation processing to produce green tea flowering loose tea. Described flower is coronoid sacrum, is commonly called as golden flower. Background technique: [0002] Green tea, also known as non-fermented tea, is a tea made from suitable new shoots of tea trees through typical processes such as greening, rolling, and drying. Its dry tea color and brewed tea soup and the bottom of the leaves take green as the main tone, hence the name. The characteristics of green tea retain more natural substances in fresh leaves. Among them, tea polyphenols and caffeine retain more than 85% of fresh leaves, about 50% of chlorophyll, and less vitamin loss, thus forming the characteristics of green tea "clear soup and green leaves, strong taste convergence". Among Chinese green teas, there are the most famo...
