摘要: 研究不同的提取温度、提取时间和提取pH值等对米糠多糖提取得率的影响。采用响应面分析的方法得到米糠多糖的最佳提取条件为:温度80.5℃,时间1.3h,pH值4.93。并在此基础上,比较了乙醇质量分数和提取液pH对米糠多糖沉淀特性的影响。

关键词: 米糠多糖, 提取, 沉淀

Abstract: The effects of temperature,time and pHon the polysaccharides recovery were investigated.With Re-sponse Surface Analysis(RSA),the optimumextracting conditions were obtained as follows:T =80.5℃,t =1.3h,pH =4.93.The effects ofalcoholconcentrationandsolutionpHonthe precipitatinproperty ofthe rice bran polysaccharides were also investig ated.
