Embodiment 1

[0017] A method for preparing tea leaves capable of decomposing fat-soluble proteins by biological fermentation, comprising the following processing steps: (1) selecting prepared tea leaves as raw materials, inoculating bacterial strains and compound enzymes; (2) biological fermentation: mixing tea leaves with bacterial strains and compound enzymes Fully mixed, the mixed product is fermented in a clean and closed container. The fermentation adopts a non-toxic and easy-to-clean solid fermentation box. The height of the fermentation material is 35cm, and the fermentation temperature is controlled at 35°C. When the temperature of the material is higher than 45°C, ventilation is used to cool down Treatment, the fermentation time is controlled at 120h; wherein, the strain and the compound enzyme are composed of the following components in weight percentage: 7% of lactic acid bacteria, 7% of yeast, 50% of Buddactobacillus, 28% of digestive enzymes, and 8% of protease; The tea leaves:...

Embodiment 2

[0019] A method for preparing tea leaves capable of decomposing fat-soluble proteins by biological fermentation, comprising the following processing steps: (1) selecting prepared tea leaves as raw materials, inoculating bacterial strains and compound enzymes; (2) biological fermentation: mixing tea leaves with bacterial strains and compound enzymes Fully mixed, the mixed product is fermented in a clean and closed container. The fermentation adopts a non-toxic and easy-to-clean solid fermentation box. The height of the fermentation material is 38cm, and the fermentation temperature is controlled at 38-40°C. Ventilation and cooling treatment, the fermentation time is controlled at 120-148h; wherein, the strain and the compound enzyme are composed of the following components by weight percentage: 5% of lactic acid bacteria, 10% of yeast, 60% of Bacillus roe deere, 20% of digestive enzyme, 5% protease; the tea leaves: sterile water: calculated by weight ratio of bacterial strains a...

Abstract

The invention relates to the field of tea processing and provides a method for preparing decomposable fat-soluble protein tea leaves by using biofermentation. The method is used for overcoming the defect in the prior art that the content of water-soluble proteins in tea leaves is low due to defects of preparation methods. The method comprises the following treatment steps: (1) selecting made tea leaves as a raw material, and inoculating the tea leaves with strains and a compound enzyme; (2) carrying out biofermentation: thoroughly mixing the tea leaves with the strains and the compound enzyme,and fermenting the mixed product in a clean and closed vessel, wherein the fermenting is carried out by adopting a non-toxic and easy-cleaned solid fermentation tank, the height of fermented materials is not greater than 40cm, the fermentation temperature is controlled to 15 DEG C to 45 DEG C, ventilation and cooling treatment is carried out when the material temperature is above 45 DEG C, and the fermentation time is controlled to 120 to 148 hours.

Description

technical field [0001] The invention relates to the field of tea processing, in particular to a method for preparing decomposable fat-soluble protein tea by biological fermentation. Background technique [0002] Tea has a long history and is one of the four major beverages. The main component of tea has a protein content of 20%-30%. Affected by the natural environment and high temperature during production, only 1%-2% can be dissolved in water and directly used. Most of it is wasted when soaking. [0003] Chinese Patent No. 201410602919.8 discloses a microwave-assisted extraction process of tea protein, including the following steps: (1) raw material pretreatment; (2) tea protein extraction; (3) rough extraction of tea protein obtained in step (2) (4) decolorization; (5) purification: the filtrate after vacuum filtration in step (4) is taken after vacuum filtration, which is the tea protein extract; (6) prepare dry tea protein Product: use alkali extraction and acid precip...
