摘要: 旨在降低紫薯的水分含量,延长保存时间。添加糖化酶和淀粉酶,采用响应面实验设计对紫薯颗粒全粉加工工艺参数进行优化,得出最优的工艺参数为蒸制时间为9 min,淀粉酶用量为130 U/g原料,糖化酶与淀粉酶之比为4:1,烘干温度为45℃,筛分目数为80目。按照此加工工艺参数制得的紫薯颗粒全粉淀粉含量最低,说明紫薯颗粒全粉品质较好,细胞破碎度较小。

Abstract: The aims are to reduce water content and prolong the preservation time of sweet potato. Glucoamylase and amylase were added in this study. The parameters of granules processing technology were optimized by response surface analysis (RSA). The optimal parameters of processing technology were as following: the steamed time was 9 min, amylase content was 130 U/g, glucoamylase : amylase was 4:1, dryingtemperature was 45℃, and sieving mesh was 80. The lowest starch content of purple sweet potato granules could be obtained according to the processing technological parameters, indicating that the quality of purple sweet potato granules was good, and the cell fragmentation was less.
