【摘要】 通过最佳提取方法的研究,确定紫心甘薯红色素的最佳提取条件为:0.5%柠檬酸,60℃恒温,1:200物料比,提取1h.在此条件下,采用二次提取工艺,可获得率为85.1%
【Abstract】 The conditions for extracting pigments from sweet potato storage roots were studied in this paper. The optimum conditions have been obtained,which include extracting reagent 0.5% citric acid,temperature 60 ℃, extracting time 1 hour, rate of root powder to the reagent 1∶200, and extracting times 2. The extracting rate reaches 85.1%.
