Method for preparing astragalus membranaceus Liupao tea

Abstract

The invention provides a method for preparing astragalus membranaceus Liupao tea. The method comprises nine steps of preparing astragalus membranaceus decoction pieces, performing wall-breaking for the astragalus membranaceus decoction pieces, preparing an astragalus membranaceus extracting solution, activating strains, removing moisture from raw tea, performing pile fermentation, performing secondary fermentation, performing natural aging and performing drying and shaping, wherein the astragalus membranaceus is subjected to wall-breaking to extract effective ingredients, the wall broken rateis 83-92 percent, the extraction efficiency for astragaloside, astragalus polysaccharide and astragalus flavone can be effectively improved, the extraction time is shortened, and the effective ingredients are protected from destruction; fermenting strains, including eurotium cristatum, penicillium, aspergillus niger, yeast and mucor, can be extracted from Liupao tea, flavor loss of Liupao tea caused by adding single strain for fermenting can be avoided, the fermenting strains are inoculated after being activated, improvement for the activity of the fermenting strains can be favored, and the fermenting efficiency of the Liupao tea can be improved; and the Liupao tea is subjected to pile fermentation, secondary fermentation and aging to achieve a good eurotium cristatum fermentation effect,nutrition of Liupao tea and astragalus membranaceus can be absorbed and transformed in the fermenting process to generate chitin, chitosan, beta-glucoside, cellulose, glycoprotein and other healthy ingredients.

Description

technical field [0001] The invention belongs to the field of tea processing biotechnology, and in particular relates to a preparation method of Huangqi Liubao tea. Background technique [0002] Liubao tea has the characteristics of "red, thick, old and mellow". The top-grade tea has betel nut fragrance and golden flower. It has outstanding weight loss effect and can improve the symptoms of energy metabolism. The effect of diuresis and detoxification is well-known in Guangdong, Guangxi, Hong Kong, Macao, Southeast Asia and other domestic and foreign markets. [0003] The basic production process of traditional Liubao tea is greening, rolling, fermenting, drying, steaming, fermenting, drying, steaming, pressing and aging. During the rolling process of Liubao tea, the leaf cells are broken, various enzymes fully contact with the substrate, and undergo chemical pre-action to form complex complexes. During the stacking process, microorganisms grow vigorously under the action of...

Problems solved by technology

The existing usage of Astragalus is mainly decocting, decocting, soaking in wine, adding to dishes, etc., but the traditional usage leads to the inability to effectively extract some beneficial components in the cells, which affects its use effect

[0006] Liubao tea and Astragalus membranaceus have their own health benefits and complement each other. However, there is no health drink prepared by organically combining Liubao tea and Astragalus membranaceus
