【Abstract】 A compound drink powder was made from Lycium barbarum and Hippophae rhamnoides through the processes including extracting juice, clarifying, concentrating, making up and centrifugal spray drying. The results showed that process of obtaining extractive Lycium barbarum juice was: breaking→thermal treatment→pressing. The mixed solution of 0.05% L AA and 0.02% NaHSO 3 is used for the protective coloration of Lycium barbarum juice. And the drying additive was maltodextrine. Its quantity was 80% of dissoluble solid content of juice. The ingredient is defined as follows: the mass ratio of Lycium barbarum to Hippophae rhamnoides was 6∶2, aspartame 0.95%, sugar 4.0% and citric acid 0.1%.更多还原
