摘要: 对油菜花粉多糖的提取工艺进行研究。探讨浸提次数、时间、料液比和温度对多糖得率的影响,在单因素试验的基础上,通过正交试验确定最佳提取工艺条件。结果表明:温度对多糖得率的影响最大,其次为提取时间、次数,料液比的影响最小。油菜花粉多糖提取的最优条件为1:4的料液比,90℃水浴条件下,浸提4次,每次浸提4h,其水溶性多糖提取率达1.450%。

Abstract: The extraction of polysaccharides from rape pollen was studied. The effects of four factors such as times of extraction,time, ratio of solid-liquid and temperature were investigated. The results showed that the effect of temperature was the mostimportant, time was the second, times was the third, and the ratio of solid-liquid was the least. Through orthogonal test, theoptimum conditions of extraction were obtained on the basis of single factor test, as follows: ratio of solid-liquid 1:4, 90℃ for3h and 4 times extraction. The extraction percent of soluble polysaccharides was 1.450% on the optimum conditions.
