The invention discloses a preparation method of tamarind
polysaccharide gel. The method includes the steps: soaking tamarind seeds into hot water, and performing
drying, peeling, crushing and screening to obtain tamarind kernel
powder; (2) dissolving the tamarind kernel
powder in hot water, stirring mixture at constant temperature, cooling the mixture, centrifugally separating the cooled mixture,and collecting liquid supernatant; (3) adding absolute ethyl
alcohol into the liquid supernatant, performing stirring and standing, soaking and cleaning precipitate, and removing solvents; (4)
drying,crushing and screening purified tamarind
polysaccharide gum; (5) adding water to dissolve the tamarind
polysaccharide gum, adding glucose, stirring mixture at constant temperature, adding absolute ethyl
alcohol until the final concentration of the ethyl
alcohol is 15%, and performing standing and refrigerating at the temperature of 4 DEG C, or standing and freezing at the temperature of 18 DEG Cbelow zero, or standing at the temperature of 25 DEG C to obtain the tamarind polysaccharide gel. According to the method, tamarind seeds directly serve as raw materials, cost is low, and the preparedtamarind polysaccharide gel is high in purity, strength and specific retention and high in anti-pressure ability and has good application prospects.
