Problems solved by technology

From the above, it can be seen that these patents are produced without exception by using mature tea as raw material, and some of them also need a stacking process. The production cycle from raw material production to flowering finished product is long and costly, which is not conducive to development and production.
[0005] The fresh leaves of tea trees in summer and autumn in my country account for about 60% of the total output of fresh leaves of tea trees in the whole year. The utilization is mainly concentrated in spring tea, resulting in a very low utilization rate of summer and autumn tea resources
According to Zheng Naihui's calculation, Xiashu tea produced in Fujian accounts for about 35%-40% of the total annual tea output, and most of them are low-grade teas with extremely low economic benefits, and some of them can't even cover the cost of mining.
The existence of this phenomenon has caused a large amount of waste of tea resources, and directly affects the production of spring tea in the coming year. It can be seen that the serious waste of fresh leaves of tea trees in summer and autumn has become a prominent problem restricting the development of my country's tea industry.
At present, there is no literature report about the direct fermentation of fresh leaves of tea trees to produce golden flower tea. Therefore, we choose fresh leaves of tea trees, especially fresh leaves of tea trees in summer and autumn, as raw materials, and inoculate golden flower fungi to ferment golden flower tea. From raw material production to development It only takes 3-6 days to make finished products from the flowers, and the production cycle is short; the developed golden flower fungus tea is full of golden flowers, rich in fungus fragrance, yellowish brown in color, mellow in taste, soft in mouth, unique in quality, and has broad development prospects

Embodiment 1

[0016] Pick 50 kg of fresh leaves of summer and autumn tea trees with one bud and one or two leaves, spread them out for 3 hours, and use a roller fixing machine (the model of the machine is not limited, the same below) to fix them at 240°C for 1 minute; spread them out in time and put them in Knead in a kneading machine (the machine model is not limited, the same below) for 20 minutes; pack the kneaded leaves into transparent glass bottles, squeeze slightly until full, seal, and sterilize under high-pressure steam at 121°C for 15 minutes; For the sterilized tea leaves, inoculate 1ml of Saccharomyces coronoidis (the strain of Saccharomyces coronoides was purchased from Wuhan Simier Biotechnology Co., Ltd., the same below) bacterial solution (spore concentration of 0.8 per 30g of sterilized tea leaves) ×10 7 spores / mL), fermented at 30°C for 4 days, took out the fermented leaves and baked them at 80°C for about 2 hours until the moisture content was 5%-7%, and about 11.5 kg of ...

Embodiment 2

[0018] Pick 150 kg of fresh leaves of summer and autumn tea trees with one bud and two or three leaves, spread them out for 4 hours, and use a roller fixing machine to fix them at 240°C for 3 minutes; Squeeze until full, seal, and sterilize under high-pressure steam at 121°C for 15 minutes; inoculate the sterilized tea leaves with 1ml of coronoid sac bacteria liquid as described in Example 1 ( The spore concentration is about 0.8×10 7 spores / mL), fermented at 25°C for 5 days, took out the fermented leaves and baked them at 100°C for about 1.4 hours until the moisture content was 5%-7%, and about 36 kg of Jinhua fungus fermented tea products were obtained. The fermented golden flower fungus tea is covered with golden golden yellow fungus on the surface of the leaves. The soup color is yellowish brown and bright, the fungus flower is rich in fragrance, and the taste is mellow and cottony.

Embodiment 3

[0020] Pick 300 kilograms of summer and autumn tea tree fresh leaves with one bud and three or four leaves, spread them out for 6 hours, and use a drum fixing machine to fix them at 280°C for 5 minutes. After the green leaves are spread out and cooled in time, put them into a kneading machine and knead for 30 minutes; put the kneaded leaves into transparent glass bottles, squeeze them slightly until they are full, seal them, and sterilize them under high-pressure steam at 121°C for 10 minutes; The tealeaves after sterilizing, inoculate 1ml by the amount of per 30g sterilizing tealeaves the coronoid process loose capsule liquid as described in the embodiment (concentration of spores is 0.8 * 10 7 spores / mL), fermented at 28°C for 5 days, took out the fermented leaves and baked them at 80°C for about 2 hours until the moisture content was 5%-7%, and about 75 kg of Jinhua fungus fermented tea was obtained. The fermented golden flower fungus tea is covered with golden golden yello...

Abstract

The invention discloses a method for producing a eurotium cristatum tea by utilizing fresh tea tree leaves. The eurotium cristatum tea is produced by taking the fresh tea tree leaves as the raw material through the processes of spreading, high temperature desiccation, rolling, sterilization, eurotium cristatum inoculation, fermentation and drying. Golden yellow eurotium cristatums are bestrewed on the surface of the eurotium cristatum tea, and the liquid of the eurotium cristatum tea is russet and bright, is strong in eurotium cristatum fragrance, and tastes sweet, mellow and soft. The invention provides a new method for fermenting the eurotium cristatum tea directly by utilizing the fresh tea tree leaves, the production cycle is short, the production cost is low, a new path is created for the development and utilization of summer and autumn fresh tea tree leaves, and the application prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and uses microbial fermentation to produce tea products, in particular to a method for producing chrysanthemum tea by using fresh leaves of tea trees.
