    • 摘要: 以枸杞干果和沙棘为原料,经取汁、澄清、浓缩、调配和离心喷雾干燥等工艺生产复合固体饮料。试验结果得出较优的工艺及配方为:枸杞取汁工艺为破碎→热处理→压榨;用0.05% L-抗坏血酸和0.02% NaHSO3护色枸杞汁;喷雾干燥使用助干剂麦芽糊精,用量占浓缩汁中可溶性固形含量的80%;饮料配方为浓缩枸杞汁与沙棘汁质量比是6∶2,蛋白糖、蔗糖、柠檬酸添加量分别为0.95%,4.0%和0.1%。

       

      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% NaHSO3 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%.
