Embodiment Construction

[0043] The present invention will be further described below in conjunction with specific embodiments.

[0044] As a preferred embodiment of the method for preparing Pu'er tea by inoculation and fermentation of the present invention, such as figure 1 , The fresh tea leaves 10, which are processed by the freshly picked tea greens, are subjected to fiber decomposition treatment 20 and sterilization treatment 30, and then the dry storage fermentation 40 is used for the processing method, which is connected to the selection and separation treatment of the aged treasure Pu'er tea 50 More than 60 strains out of 51 to ferment;

[0045] In the fiber decomposition treatment 20, fresh tea leaves 10 are placed under fermentation conditions, and the bacteria of Bacillus licheniformis 21 and Pseudomonasaeruginosa 22 are fermented to decompose the fibers of the tea and release the tea components. And soften

[0046] In the sterilization treatment 30, the fresh tea leaves 10 are sterilized by the ...

Abstract

The invention discloses a method for processing Pu'er tea by bacterial fermentation. The method comprises the following steps: subjecting freshly-harvested tea leaves to fiber decomposition treatment and sterilization treatment, and inoculating at least one bacterial strain isolated from Pu'er tea that is preserved for a long time to allow fermentation based on the treatment of dry-house fermentation. The method significantly shortens the fermentation time, increases the contents of statin, gamma-aminobutyric acid and polyphenols during the fermentation stage, enhance the activity of scavenging DPPH free radicals, and produces Pu'er tea with the similar flavor and fragrance as the preserved Pu'er tea.

Description

Technical field [0001] The invention relates to a method for preparing Pu'er tea by inoculation and fermentation, in particular to a method that can shorten the fermentation time of fresh tea leaves during the process of making Pu'er tea, and can increase statin and gamma-aminobutyrate during the fermentation. The preparation method of inoculated and fermented Pu'er tea with the content of acid and polyphenols and the improvement of DPPH free radical scavenging activity can produce finished products with flavor and aroma comparable to that of aged treasure Pu'er tea. Background technique [0002] Following animal and human trials on tea to prevent cancer and lower blood lipids, recently, statin (Statin) has been confirmed from Pu'er tea extract. Clinical trials have confirmed that: Statin can lower blood pressure, lower blood lipids, lower cholesterol and reduce inflammation, thereby reducing the onset of coronary artery and cerebrovascular diseases. [0003] The processing method...
