Abstract

The invention discloses glucan beverage and a preparation method thereof. The preparation method comprises the following steps: (1) inoculating a leuconostocmesenteroides fermented culture in a fermentation medium, carrying out aerobic cultivation to obtain a fermentation broth; (2) uniformly mixing the fermentation broth and a blending liquid with a sweetener and an acidulant, homogenizing and sterilizing, wherein the fermentation medium comprises sucrose and a tomato juice water solution; the volume percent concentration of tomato juice in the tomato juice water solution is 40-100%; the pH value of the fermentation medium is adjusted to 6.0-8.0 with alkali; the volume percent of the fermentation broth in the glucan beverage is 15.5-66.6%. The beverage is low in cost, natural and safe, glucan is obtained through fermentation, the reality that the polysaccharide of beverage on the market is from a plant and is added manually is broken, the innovation and the safety of the product are improved, and the prospect is wide.

Description

technical field [0001] The invention discloses a dextran beverage and a preparation method thereof. Background technique [0002] Polysaccharide is a macromolecular polymer composed of monosaccharides bonded by glycosidic bonds. Studies have shown that polysaccharides have beneficial functions such as immune regulation, anti-virus, anti-cancer, hypoglycemic, and blood pressure. Polysaccharides in nature are mainly distributed in microorganisms, higher plants, animals, lichens, and algae. Among them, polysaccharides derived from microorganisms, especially exopolysaccharides, are the growth of certain microorganisms (such as lactic acid bacteria, Agrobacterium, Rhizobium, etc.) A class of carbohydrate compounds that are secreted outside the cell wall during metabolism. Among them, the polysaccharide attached to the outside of the microbial cell wall is called capsular polysaccharide, while the mucus polysaccharide exists in the form of permeation in the growth environment. ...
