摘要: 通过干热反应制备大豆蛋白-多糖共价复合物,并结合聚丙烯酰胺凝胶电泳验证了大分子复合物的共价结合。对于蛋白与多糖生成共价复合物的Maillard反应路线进行了分析,阐明对于蛋白与多糖在相对温和的反应条件下得到的主要是Maillard反应步骤中的第二步,属于Amadori产物中的一类,并采用红外光谱分析了产物分子结构特征。

Abstract: Abstract】 A functional soybean acid-precipitated protein (SAPP)-polysaccharide conjugate was prepared by dry-heat medium temperature (60℃) treatment. The covalent attachment of polysaccharides to protein was confirmed by SDS-PAGE. The reaction path of protein-polysaccharide Maillard reaction was analyzed. It was reported that the protein-polysaccharide products were obtained in 2 steps, and could be acceptably put in the products as the Amadori groups. The molecular structure features of conjugate were analyzed through IR-spectrums.  AbstractFilter('EnChDivSummary','ChDivSummaryMore2','ChDivSummaryReset2');
