| 摘 要： | 研究了米糠多糖的提取和分离工艺。该工艺运用微波辅助提取多糖,所得多糖提取液经一定体积分数的乙醇沉淀等工艺后,得到米糠多糖。采用单因素实验和正交实验对米糠多糖的醇沉工艺进行了优选。试验得出最佳醇沉工艺条件为:料液比为1∶3,醇沉用乙醇的体积分数为80%,室温静止5h。该工艺提取所得米糠多糖的提取率达到2.4%。

| Abstract: | The technology of extraction and separation of polysaccharide from rice bran was studied. The polysaccharide in rice bran was extracted by microwave-assisted. Based on this study a mature extraction process of polysaccharide was put forward. And the optimum was obtained by orthogonal test:the polysaccharide was deposited with pure ethanol(the content of ethanol was up to 80%)for 5 h. With this technology the yield of polysaccharide was up to 2.4%. |
