澄清型紫薯汁加工工艺的研制

The development of clear purple potato juice processing technology

试验以紫薯为主要原料,研究澄清型紫薯汁的加工工艺。通过正交试验及验证实验,确定澄清型紫薯汁生产的工艺为:紫薯干片制备工艺参数为薯片厚度3mm,干制温度80℃,干制时间7h;澄清型紫薯汁生产配方为白砂糖4%,葡萄糖3%,海藻糖3%,柠檬酸0.1%,羧甲基纤维素钠0.1/%,食盐0.05%,山梨酸钾0.03%,红薯香精0.01%,紫薯干片5%。

With purple potato as the main raw material,the processing technology of the clear purple potato juice was studied.orthogonal test and verification experiments determine production process of clear purple potato juice as follows：Preparation process parameters of purple potato piece：potato chips thickness is 3mm,dehydrated temperature is 80 ℃,dehydrated time is 7h;production formula of clear purple potato juice：sugar is 4%,glucose is 3%,trehalose is 3%,citric acid is 0.1% and sodium carboxy methyl cellulose is 0.1 / %,salt is 0.05%,potassium sorbate is 0.03%,sweet potato essence is 0.01%,purple potato piece is 5%.
