正交试验优选大理百合多糖提取的工艺

Optimizing Technique of Extracting Polysaccharide from DaLi Lilium brownie by Orthogonal Test

对热水法提取大理百合多糖的工艺进行优化;采用了L(934)正交试验对提取温度、提取时间、固液比和提取次数等工艺参数进行优选;影响大理百合多糖热水提取的主要因素是提取温度,其次是料液比,再次是浸提次数和提取时间;热水法提取大理百合多糖的优化提取条件为:温度60℃,固液比1∶8(v/v),浸提时间7h,浸提次数2次。

Optimizing technics of extracting polysaccharide by hot water method from Dali Lilium brownie.In this reseach L（934）orthogonal design was used to optimize technological parameters of extraction such as temperature,extraction time,ratio of material with liquid and extraction times.The temperature was the main factor which effected the extracting rate of Dali Lilium brownie,ratio of material with liquid was the secondly factors,then was the extraction times and extraction time.The optimum extraction conditions were temperature at 60 ℃,solid/liquid of 1：8（v/v）and reflux time of 7 h with 2 times.
