螺旋藻多糖提取新工艺研究

A Study on the New Process to Separate Polysaccharide from Spirulina Platensis

研究了以三氯乙酸 ( TCA)沉淀蛋白质提取螺旋藻多糖的工艺方法 ,讨论了提取液体积、p H、提取温度 ,提取时间以及 TCA使用方法对提取效果的影响 ,在最佳实验条件下 ,得到产品为白色粉未 ,提取率 1 .30 %～ 1 .37% ,产品中多糖质量含量 93.8% ,蛋白质质量含量 <6%。

A new method is studied to separate polysaccharide from spirulina platensis. The effects on separation of the solvent amount, the pH of solvent, the time and the temperature are also discussed. Under the best condition of separation, the white polysaccharide powder can be obtained. The yield rate is 1.30～1.37, the purity is 93.8% and the amount of protein is less than 6%.
