Method for producing winter jujube vinegar drink and extracting winter jujube polysaccharide from jujube dregs

Abstract

The invention discloses a method for producing winter jujube vinegar beverage and extracting winter jujube polysaccharide from winter jujube residues, and belongs to production of the winter jujube vinegar beverage and extraction of winter jujube polysaccharide. The method comprises the following steps: (1) enzymolysis of winter jujube residues; (2) alcohol fermentation; (3) acetic acid fermentation; (4) centrifugation and filtration; (5) ultrafiltration; (6) preparation of the winter jujube vinegar beverage, namely 6.1. conditioning of the winter jujube vinegar beverage, 6.2. filtration, and 6.3. filling; (7) preparation of the winter jujube polysaccharide, namely 7.1. activated carbon decoloration, 7.2. trichloroacetic acid deproteinization, 7.3. refined filtration and 7.4. drying. Compared with the prior art, the method for producing winter jujube vinegar beverage and extracting winter jujube polysaccharide from winter jujube residues disclosed by the invention has the advantages that resources are saved, the jujube residue leftovers are recycled and are changed into valuable things to be reutilized, so that pollution is alleviated, the enterprise cost is lowered, and the enterprise burden is lowered; the environmental-friendly effect is realized, and winter jujubes are utilized thoroughly truly, so that promotion and application values are good.

Description

technical field [0001] The invention relates to the production of winter jujube vinegar drink and the extraction of winter jujube polysaccharides, in particular to a method for producing winter jujube vinegar drink and extracting winter jujube polysaccharides from winter jujube jujube dregs, which are leftovers of winter jujube concentrated juice. Background technique [0002] Plant polysaccharides can inhibit diabetes, gastric ulcer, pain and other diseases, and also have the effect of lowering serum cholesterol and promoting animal growth. Plant polysaccharides can enhance the body's specific and non-specific immunity, directly or indirectly activate B lymphocytes, T lymphocytes and macrophages, and have therapeutic and inhibitory effects on tumors, diabetes, hyperlipidemia, hypercholesterolemia and other difficult diseases. A large number of studies have shown that many plant polysaccharides have inhibitory effects on bacteria and viruses, such as HIV, herpes simplex viru...
