Method for preparing steeping liquor rich in waxberry polyphenol

The invention relates to a method for preparing steeping liquor rich in waxberry polyphenol. The method comprises the following steps: a, preparing waxberry liquor, namely, fermenting waxberry with dregs, removing the fermentation liquid so as to obtain waxberry fruit dregs, and distilling, thereby obtaining waxberry liquor; b, extracting waxberry polyphenol, namely, drying and screening the waxberry fruit dregs, and extracting waxberry polyphenol by using a composite enzymolysis approach; c, adding fresh waxberry fruits and waxberry polyphenol prepared in step b into the waxberry liquor prepared in the step a, sufficiently stirring, and soaking for 10-15 days at 25-30 DEG C; and d, separating the soaked waxberry liquor from the fresh waxberry fruit, filtering the waxberry liquor, and clarifying, thereby obtaining the steeping waxberry liquor. According to the method for preparing steeping liquor rich in waxberry polyphenol, the waxberry fruit dregs are taken as a raw material which is distilled to obtain waxberry liquor, waxberry polyphenol can be separated from waxberry fruit dregs, comprehensive utilization of waxberry can be achieved, and the steeping waxberry liquor prepared by using the method is rich in waxberry polyphenol.
