The invention provides a method for preparing cold-soluble instant
ampelopsis grossedentata
powder through double-effect extraction. The method comprises the steps of
raw material treatment, double-effect extraction,
filtration,
settling separation, concentration, blending, sterilization,
drying and the like. According to the method, the selectivity of the raw materials is wider, and the cost is reduced while the yield is increased; compared with the traditional process, the process flow is more convenient and faster, the product form and
flavor characteristics are richer and more diversified, the
raw material utilization rate is higher, and the production
energy consumption is lower. The two products can be quickly cold-dissolved at normal temperature, so that the
brewing convenience is greatly improved; by adding a certain proportion of beta-cyclodextrine and
maltodextrin, substances easy to separate out can be effectively embedded, so that the
solubility of the instant
ampelopsis grossedentata
powder is greatly improved; the two instant
ampelopsis grossedentata
powder have excellent cold dissolving effects, the content of dihydromyricetin in the two instant
ampelopsis grossedentata powder is greater than 25%, and the instant
ampelopsis grossedentata powder has an effective health-care function.
