Problems solved by technology

[0005] (1) This processing method is greatly affected by the types and communities of microorganisms in the fermentation environment, and the reproduction of a large number of mycelia will easily cause Pu-erh tea to agglomerate, and the strips will be loose and dull; (2) The types of microorganisms in the environment are unknown and there are many miscellaneous bacteria 1. The community structure is complex, the fermentation process is unstable, and the Pu'er tea has a strong earthy taste; (3) It is impossible to form directional fermentation, and it is difficult to control and standardize the production method, resulting in unstable product quality, and it is impossible to realize the standardized and characteristic production of Pu'er tea

Embodiment 1

[0020] S1: Use Yunnan big leaf sun-dried green tea as raw material and place it in a fermenter for pile fermentation. The water content of the tea pile is 30% by spraying, and the compound starter A with 1% of the tea pile mass is dissolved in the tide water. The composite starter A is compounded with xylose, Aspergillus niger, and Penicillium in a mass ratio of 3:1:1, and the first turning is carried out after 4 days, and the temperature is kept at 30°C before turning;

[0021] S2: After turning the heap for the first time, add the compound yeast preparation to the tea heap, spray the compound yeast preparation by dissolving it in water, keep the water content of the tea heap at 30% after spraying, and turn the heap for the second time after 4 days, Keep the temperature at 25°C before turning the pile for the second time. The compound yeast preparation is compounded by Candida rugosa and Aspergillus niger in a mass ratio of 2:1. The spraying amount of the compound yeast prepar...

Embodiment 2

[0025] S1: Yunnan big leaf sun-dried green tea is used as raw material and placed in a fermenter for heap fermentation. The water content of the tea heap is 35% by spraying, and a compound starter A with a mass of 1.5% of the tea heap is dissolved in the tide water. The compound starter A is compounded with fructose, Aspergillus niger, and Penicillium in a mass ratio of 3:1:1, and the first turning is carried out after 5 days, and the temperature is kept at 33°C before turning;

[0026] S2: After turning over the pile for the first time, add the compound yeast preparation to the tea pile, spray the compound yeast preparation by dissolving it in water, keep the moisture content of the tea pile at 35% after spraying, and perform the second pile turning after 5 days, Keep the temperature at 28°C before turning the heap for the second time. The compound yeast preparation is composed of Candida rugosa and Aspergillus niger in a mass ratio of 2:1. The spraying amount of the compound ...

Embodiment 3

[0030] S1: Use Yunnan big leaf sun-dried green tea as raw material and place it in a fermenter for pile fermentation. The water content of the tea pile is 40% by spraying, and a compound starter A of 2% of the tea pile mass is dissolved in the tide water. The compound starter A is compounded with mannose, Aspergillus niger, and Penicillium in a mass ratio of 3:1:1, and the first turning is carried out after 6 days, and the temperature is kept at 35°C before turning;

[0031] S2: After turning over the pile for the first time, add the compound yeast preparation to the tea pile, spray the compound yeast preparation by dissolving it in water, keep the water content of the tea pile at 40% after spraying, and perform the second pile turning after 6 days, Keep the temperature at 30°C before turning the heap for the second time. The compound yeast preparation is composed of Candida rugosa and Aspergillus niger in a mass ratio of 2:1. The spraying amount of the compound yeast preparati...

Abstract

The present invention discloses a staged exogenous auxiliary fermentation method of Pu'er tea, and the method comprises a pile fermentation step, and the pile fermentation step comprises at least two times of pile turning, a composite fermentation agent A is sprayed before the first pile turning, the first pile turning is performed in 4-6 days, a composite yeast preparation is added after the first pile turning, and the second pile turning is performed in 4-6 days, a compound enzyme preparation is added after the second pile turning, wherein the composite fermentation agent A is prepared by compounding reducing sugar, aspergillus niger and penicillium according to a mass ratio of 3:1:1. Due to the fact that the composite fermentation agent A, the compound enzyme preparation and the compound enzyme preparation are added into a tea pile in stages, dominant strains can be guided to be formed in different fermentation periods, meanwhile, the occurrence of other strains is reduced or even inhibited by means of the antagonism of organisms, the fermentation time can be effectively shortened to 11 days at the minimum, however, the quality of the fermented tea is not deteriorated.

Description

technical field [0001] The invention relates to the field of Pu'er tea fermentation, in particular to a stage exogenously assisted fermentation method of Pu'er tea. Background technique [0002] Pu-erh tea is a special type of post-fermented tea formed by natural or artificial assisted fermentation process under the action of microorganisms. Due to its unique flavor, soup color and significant anti-oxidation, blood lipid lowering, cardiovascular protection, antibacterial and anti-tumor and other biological activities and health effects, it has attracted much attention and has a good market prospect. [0003] The heat and humidity during the fermenting process of Pu-erh tea creates a good environment for the growth and metabolism of microorganisms. Various metabolic products, especially the secreted enzymes, make the tea cells separate from each other, the cell wall is dissolved, and the intracellular substances A series of oxidation-reduction reactions occur, resulting in a...
