摘要: 大豆多糖是大豆中的有效活性成分之一,具有抗氧化性、食品稳定性等作用。本实验从大豆豆渣中提取可溶性大豆多糖的主要影响因素进行了正交实验,对提取物进行薄层层析(TLC)和傅立叶变换红外光谱分析(FTIR)的单糖组分与结构分析。通过对提取温度、保温时间、pH值、固液比等对大豆多糖的提取影响4个因素的正交试验,结果是最佳提取组合条件为提取温度在100℃,保温时间为3h,固液比1:2,pH值为5时为产率最高。并将提取的多糖经过初步纯化后,经薄层层析分离的纯化制备样品与半乳糖、阿拉伯糖和鼠李糖等部分单糖的组分分析和红外光谱的样品糖结构分析。

Abstract: Soluble soybean polysaccharide(SPSS)is one of the effective ingredients in soybeans,and it has various functions,such as antioxidant activity,stabling protein particles in acidic solutions,etc.The research mainly emphasizes on the extraction of soybean polysaccharide(ESP),and then analyzes its monosaccharide components.The ESP primarily focuses on the quantities of SSPS under different temperatures,time,pH,as well as conditions of varied firm than liquid,thus finds out the optimum arrangements of the four factors,namely temperature 100 ℃,time 3 h,pH5,and firm than 2 liquid.After the elementary purification,the extraction is identified with TLC(Thin Layer Chromatography)and FTIR(Fourier Transform Infrared Spectroscopy)for its monosaccharide constiutions.
