| titleOfInvention | Method for extracting probiotic functional sugar from distilled rice wine distillation residual liquid |
| abstract | The invention belongs to the field of polysaccharide extraction, and particularly relates to a method for extracting probiotic functional sugar from distilled rice wine distillation residual liquid. The method comprises the following steps: concentrating the distillation residue of distilled rice wine; adding ethanol solution into the concentrated distilled rice wine distillation residual liquid until the final concentration of ethanol is 30%, precipitating with ethanol, and centrifuging; taking supernatant, adding ethanol solution until the final concentration of ethanol is 75-85%, precipitating with ethanol, and centrifuging; concentrating the supernatant obtained by centrifugation, and freeze-drying to obtain rice wine crude polysaccharide; dissolving the rice wine crude polysaccharide to obtain a rice wine crude polysaccharide sample liquid, and removing protein by adopting a Sevage reagent, wherein the dosage ratio of the Sevage reagent to the rice wine crude polysaccharide sample liquid is 1: 3-6; and putting the deproteinized rice wine polysaccharide sample liquid into a dialysis bag with molecular weight cutoff of 3500Da for dialysis in ultrapure water, and then concentrating, freezing and drying to obtain the target probiotic functional sugar. The polysaccharide extracted by the method has high yield and high purity, and has better effect than inulin in the process of promoting the proliferation of the bifidobacterium breve. |
