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.
