摘要
利用水浸法提取洋葱中的多糖,采用正交试验优化了工艺条件,结果表明:影响洋葱多糖得率的主次因素顺序为料液比>提取温度>提取时间。最佳的提取工艺参数为:料液比1∶25,提取温度70℃,提取时间5 h。在此条件下,洋葱多糖得率可达到4.54%。
Water extraction of polysaccharide from onion was optimized by an orthogonal test.The results show that the extraction rate of polysaccharide is mostly influenced by ratio of solid-liquid,followed by extraction temperature and extraction time.The optimum process parameters are ratio of solid-liquid 1∶25,extraction temperature 70 ℃ and extraction time 5 h.Under these conditions,the extraction yield is up to 4.54 %.
