质量作用

It was found, several products with different molecular weight can be separated from a rough dextran and UF process was enhanced observably by an electric field. There is an optimal voltage corresponded to different concentrations. Based on mass balance, gradational UF can be used as a simple and effective method for biomacromolecular analysis.

实验结果表明，分级超滤法能从单一的粗品中分离出分子量范围不同的多个产品；外加电场对超滤过程有较明显的强化作用，不同浓度的料液存在其对应的最佳外加电压；基于质量衡算的分级超滤可以作为生物大分子物质的一种简便而且有效的分析手段。

According to the results of the orthogonal experiment and its actural application,the ideal extraction process of SSPS was solid-liquid ratio:1∶20,extraction temperature:120 ℃,extraction pH:3,extraction time:1.5 hours.Among these factors the extraction temperature had the greatest influence on the extraction ratio of SSPS,extraction pH and extraction time also had influence on the yield of SSPS.SSPS at concentration of 4.0 g/L could stabilize acid dairy beverage which was prepared with 36 g/L skim milk and 50 g/L sugar at pH 4.0.The stability of SSPS was similar to that of pectin,but superior to that of Acacia gum,PGA and CMC.

结果表明，从豆渣中提取大豆水溶性多糖的最佳工艺为固液质量比1：20，提取pH=3，提取温度120 ℃，提取时间1.5 h；对多糖提取率影响最大的因素是提取温度，其次是提取pH和提取时间；提取的大豆水溶性多糖在添加量为4.0 g/L、pH为4.0的酸性乳饮料中，其稳定作用最好，稳定效果与果胶相似，而明显优于阿拉伯胶、PGA和CMC。
