蟹爪兰红色素提取工艺的研究

Study on extracting method of red pigment in Schlumbergera truncatus

利用正交实验设计和Duncan法检验,确立了蟹爪兰中红色素的最佳提取条件及其产率.结果表明,每1 g蟹爪兰干花粉用150 mL的50%乙醇溶液,在20℃恒温浸提1.5 h,提取效率较好.该法红色素提取粗产率为9.7%.

It was studied the extracting method and production of Schlurnbergera truncatus red pigment in orthogonal test L9 （3^4）. The results of the experiment showed that the extracting condition of good yields of pigment could be obtained by 50% C2H5OH solution at 20℃ for 1.5 h with the solidliquid ratio 1 g ： 150 mL and the productivity is 9.7%.
