Kombucha and preparation method thereof

Abstract

The kombucha is prepared from the following raw materials: tea, cane sugar or glucose, water, compound polysaccharide enzyme, saccharomycetes, lactic acid bacteria, xylitol, galactooligosaccharide GOS and acetic bacteria. The GlcUA content of the kombucha reaches 2.2 g / L or above, and the DSL content of the kombucha reaches 3.3 g / L or above. The preparation method of the kombucha comprises the following steps: mixing the black tea, the cane sugar or the glucose and the water according to a certain proportion, performing heat preservation extraction, adding the composite polysaccharide enzyme, and treating for about 1-3 hours; removing tea leaf residues, sterilizing filtrate, cooling to inoculation temperature, inoculating saccharomycetes and lactic acid bacteria, fermenting for about 3 days, adjusting the pH value to 5.0 or above, adding the xylitol and the galactooligosaccharide GOS, inoculating acetic bacteria, and continuously fermenting until the mixture is mature; and removing insoluble substances from the obtained mature fermentation liquor in a centrifugation or membrane filtration manner, wherein the obtained filtrate is the kombucha containing a large amount of GlcUA and DSL. According to the invention, the content of GlcUA and DSL is increased, so that the technical effect of effectively improving the health-preserving and health-care effects of the kombucha is achieved.

Description

technical field

[0001] The invention relates to the technical field of health drinks, in particular to a kombucha fungus, especially a kombucha fungus and a preparation method thereof. Background technique

[0002] Kombucha is made by mixing and fermenting black tea (or green tea, oolong tea, Kuding tea, flower tea, etc.), white sugar (or rock sugar, honey and other sugar sources) and water through a variety of microorganisms. Mature kombucha will produce a layer of fungus, which resembles the skin of jellyfish, so it is called "Haibao"; because kombucha can help digestion and treat various stomach diseases, it is called "weibao" in some places; Kombucha is made from black tea water and white sugar into a bacterial liquid containing yeast, acetic acid bacteria and lactic acid bacteria, so it is also called "kombucha", and it is generally called "kombucha" abroad. Kombucha is rich in glucuronic acid (GlcUA), D-glucaric acid-1,4-lactone (DSL), vitamin C, vitamin B and other n...
