Abstract

The invention belongs to the technical field of ginger polysaccharide processing, and particularly discloses a preparation method of high-quality ginger polysaccharide. The preparation method comprises the following steps: selecting materials, sorting, cleaning, slicing, juicing, filtering, heating, drying, extracting, centrifuging, carrying out rotary evaporation, centrifuging, washing, carryingout reduced pressure drying and the like. According to the preparation method of the high-quality ginger polysaccharide, a hot water extraction and enzymolysis synergistic method is adopted, and a hotwater extraction method and a composite enzymolysis method are organically combined so that the preparation method has the advantages of high ginger polysaccharide extraction rate and yield of the composite enzymolysis method and high extraction purity of the hot water extraction method, the extraction rate and quality of the ginger polysaccharide are improved, and the polysaccharide in ginger peel can be effectively extracted; the peeling cost in the traditional ginger polysaccharide extraction technology is reduced, the yield is increased, the ginger peel polysaccharide is extracted from the ginger peel, the pollution of the ginger peel to the environment is reduced from the perspectives of energy and the environment, the industrial value of the ginger is increased, the method has extremely important research significance, and the ginger polysaccharide finished product has the characteristics of few impurities, fineness, high solubility and high nutrient content.

Description

Technical field[0001]The invention relates to the technical field of ginger polysaccharides, in particular to a method for preparing high-quality ginger polysaccharides.Background technique[0002]Ginger is the fresh rhizome of the ginger family plant ginger. It has the effects of relieving the surface and dispelling cold, warming up and relieving vomiting, warming the lungs and relieving cough, and detoxifying. , Mentioned in "Shen Nong's Materia Medica" and "Compendium of Materia Medica".[0003]However, the current methods for extracting ginger polysaccharides mainly include hot water extraction, ultrasonic ice bath extraction, and complex enzymatic hydrolysis. According to the literature, there are three extraction methods: hot water extraction, ultrasonic ice bath extraction, and complex enzymatic hydrolysis. The extraction rates of polysaccharides obtained under the optimal extraction conditions of the process were (11.74±0.23)%, (7.00±0.04)%, (20.93±0.20)%, and the yields were (6...
