Preparation method of health-care health-preserving black tea ferment beverage

Abstract

The invention relates to a preparation method of a health-care health-preserving black tea ferment beverage. The preparation method comprises the following steps of taking dark tea and sugar stevia leaves, adding water for soaking, performing decoction, performing low-temperature vacuum decompressed concentration on the decoction liquid, performing sterilization, and performing filtering, whereinfiltrate is a nutrient solution; adding brown sugar to the nutrient solution, and performing uniform mixing to obtain a culture solution; and placing the culture solution in a fermenter, performing cooling, performing inoculating with rhizopus oryzae and red yeast rice strains, and then performing sealed fermentation for 3-6 months, wherein the fermentation temperature is 35-37 DEG C, so that thebeverage is obtained. The dark tea and the sugar stevia leaves are used as a culture medium of the nutrient solution, and composite fermentation of the rhizopus oryzae and the red yeast rice strains is a transformation tool. A conventional deep-layer liquid state fermentation technology is adopted, so that the health-care health-preserving efficacy of original dark tea can be improved, and activesubstances generated by zymocyte fermentation can be increased. The health-care health-preserving black tea ferment beverage is safe and free from toxin. The obtained beverage is a purely natural fermentation metabolism product, is free from any preservative and high in nutrient value, has various health-care health-preserving efficacy, and is suitable for various crowds to drink.

Description

technical field [0001] The invention belongs to the field of tea product processing, and in particular relates to a method for preparing a health-care dark tea enzyme drink. Background technique [0002] The word "black tea" was first seen in the third year of Jiajing in the Ming Dynasty (1524) in the imperial censor Chen Jiang's memorabilia: "The commercial tea is low-faith, and black tea is collected. The real estate is limited, and it is still the second grade of the upper middle school. It is printed on the branding strip. , The name of the bookseller is tested. Every ten catties is steamed and sun-dried, and transported to the tea department. Dark tea belongs to one of the six major tea categories, and it is a post-fermented tea. It is mainly made by microbial fermentation and heat and humidity. Because the manufacturing process often requires accumulation and fermentation for a long time, the leaves are mostly dark brown. Therefore, it is called black tea by people. ...

Problems solved by technology

Drinking brewed black tea cannot fully absorb the nutrients of black tea, resulting in a waste of resources

However, the various accessory products developed for dark tea and their production techniques cannot achieve the purpose of making full use of dark tea at present, so it is particularly important to develop a method for preparing dark tea enzymes to overcome the deficiencies in the prior art
