【摘要】 研究了碱提酸沉法和醇法提取功能性大豆低聚糖的工艺,并通过正交试验对两种提取方法的工艺进行了优化,结果为:碱提酸沉法提取大豆低聚糖的最佳工艺为:pH9、时间1 h、温度70℃、料液比1∶14;而醇法提取大豆低聚糖的最佳工艺为:乙醇浓度50%、温度50℃、时间80 min、料液比1∶12。对两种方法进行比较,结果表明:两种方法提取大豆低聚糖的提取率基本相同,但醇法浸提大豆低聚糖的浓度明显高于碱提酸沉法。更多还原

【Abstract】 The technologies of alkali and ethanol methods to extract soybean oligosaccharides are studied.They are optimized by orthogonal experiments.It is proved that the best condition of alkali method to extract soybean oligosaccharides is pH9,1 h,70 ℃,the ratio of material and water 1∶14 and the best condition of ethanol method is ethanol 50%,50 ℃,80 min,the ratio of material and water(1∶12).The two methods are compared.The results show that the oligosaccharides extract-ratio of the two methods are almost the same,but the concentration of oligosaccharides extracted by the ethanol method is higher than the other one.更多还原
