摘要
采用微波辅助法,从薯莨块茎中提取色素,以蒸馏水作为提取溶剂,在单因素试验基础上,通过正交试验优化提取工艺条件,分别考察了微波功率、微波时间以及料液比对薯莨色素提取率的影响。结果表明,以蒸馏水为提取剂,微波功率250 W、时间6 min、料液比1:25时,薯莨色素提取率可达85.7%。
Lour. was studied The microwave-assisted extraction technology of pigments from the tubers of Dioscorea cirrhosa Distilled water was the extraction solvent. The effects of microwave power, microwave time and the ratio of solid to liquid on extraction rate of pigments were investigated by single factor and orthogonal design methods The results showed that the optimal conditions were microwave power 250 W, extraction time 6 min, ratio of solid to quid 1 ： 25, by which the extraction rate of pigments reached 85.7%
