Production method of purple yam clear juice beverage and product thereof

Abstract

The invention provides a production method of a purple yam clear juice beverage and a product thereof and belongs to the technical field of deep processing of agricultural products. The production method includes: raw material purple yam pretreatment, pulping, amylase enzymolysis, compound enzyme enzymolysis, centrifuging for residue removal, mixing for filling, and sterilizing. A biological enzymolysis method is adopted to decompose ingredients like starch and protein in purple yam, so that juice yield and solid content are increased, and healthcare effect of functional ingredients like rich anthocyanin in the purple yam is brought into full play. Starch is hydrolyzed into sugar, so that only a small amount of sugar or sweetener needs to be added. Through degradation of macromolecular substances like starch and protein and control of acidity and treatment temperature, massive generation of precipitate in the process of production and storage is avoided, and product quality is improved. The product is reasonable in technology and simple in process, and the beverage is bright in color and luster, transparent, fresh and cool in taste and wide in market prospect.
