摘要
采用浸提法从黄玉米中提取天然色素玉米黄。实验选择了浸提溶剂 :无水乙醇与石油醚重量比为 1∶ 4的混合溶剂 ;找出了色素提取的最佳条件 :溶剂与玉米粉的重量比例为 2∶ 1 ,浸提时间为 1 .5h,浸提温度为 55℃ ,浸提次数为二次。初步设计出了成品色素生产的工艺流程。
This thesis is on the extraction process of natural maize pigment from yellow maize.Commercial product flow chart is designed under the optimal experimental operation conditions.The extraction process is to take 1 weight of maize powder into 2 weights of solvent extracting 1.5 hours at 55℃.Each was extracted two times.The solvent composed 1 weight of ahydrate alcohol and 4 weights of petroleum ether.
