摘要
以酶解紫薯汁和发芽糙米汁为原料,添加其它配料,制备紫薯-发芽糙米复合饮料,通过单因素试验和正交试验优化工艺参数。最佳酶解条件为α-淀粉酶用量2.5%、酶解温度65℃和酶解时间60 min;调配的最佳配方为紫薯汁和发芽糙米汁的质量比7∶3、糖用量6%、柠檬酸用量0.010%和羧甲基纤维素钠0.20%,此时得到的复合饮料品质最佳。
With hyclrolyzed purple sweet potato juice and germinated brown rice juice as raw materials, the compound beverage of purple sweet potato-germinated brown rice was prepared by mixing with other ingredients. After single-factor experiment and orthogonal experiment, the optimum conditions for hydrolysis were：addition of 2.5%, a-amylase for 60 rain at 65 ℃ ; The best formula was as follows： mass ratio of purple sweet potato juice to germinated brown rice juice 7 ： 3, sugar content 6%, citric acid content 0.010% and CMC-Na 0.20% .The results showed that a favorable compoud beverage could be obtained under these conditions.
