| 摘 要： | 试验研究了从啤酒酵母中提取胞壁多糖的提取工艺。提取工艺路线为:酵母溶解→冻融→超声波破碎→碱溶→中和→沉淀→洗涤→烘干。通过正交试验对酵母破壁和碱溶条件进行优化,寻求最佳的工艺条件,多糖得率为19.4%,用苯酚-硫酸法测定多糖的含量为51.9%。

| Abstract: | This experiment is studying on the craft of polysaccharides extraction from beer yeast cell-wall.The craft route drawn: yeast dissolve→freeze thawing→ultrasoinc crush→alkali abstraction→neutralize→deposit→solvent wash→dry. Seek the best craft condition,as well as optimize conditions of crush wall and alkali dissolving by orthogonal experiment, yield of polysaccharide is19.4%. Determination with phenol-sulphuric aicd law, content of polysaccharide is51.9%. |
