摘要
报道了以有机溶剂浸提法从黄姜中提取黄色素工艺研究,重点在单因素的基础上,通过正交试验系统地探讨了温度、时间、料液比、提取次数等因素对黄色素提取的影响,得到了优化工艺参数。粗提物通过醚类有机溶剂萃取精制,色价高于16,收率为1.42%。
Yellow pigment was extracted with ethanol and water from Dioscorea zingiberensis. The effects of temperature, time, ratio of raw material and solvent on the extracting of yellow pigment were ascertained. Based on the results of single factor experiments and orthogonal experiments, the best extraction processing parameter was obtained. The yellow pigment purified by solene could be obtained with the yield at 1.42% and the colority more than 16.
