摘要
采用内部沸腾法优化螺旋藻多糖提取工艺.利用正交实验设计分析乙醇浓度、料液比、提取温度和时间对螺旋藻多糖得率的影响.结果表明:用内部沸腾法提取螺旋藻多糖的最佳条件为:40%乙醇,料液比1∶14,温度80℃,提取时间5min,多糖得率是8.92%.内部沸腾法快速、高效、经济,可有效用于螺旋藻多糖的提取.
Polysaccharides from Spirulina Platensis were extracted by inner ebullition method.The effects of parmeters ranged？from concentration of ethanol,solid-liquid ratio,extraction temperature,and time on the yield of Polysaccharides were investigated by orthogonal experiment.Experiment results show that the optimum extraction conditions are as followed：the volume fraction of ethanol solution saturated the materials is 40%,the ratio of material to solution was 1：14（g/mL）,the extraction temperature was 80℃,extraction time was 5 min.The extraction rate of polysaccharides reached 8.92% under the optimum extraction.The method of inner ebullition is a rapid,efficient,economic method to extract the polysaccharide fromSpirulina Platensis.
