This study compliments previous work where peroxidase was successfully used to crosslink corn fiber gum (CFG) with bovine serum albumin and improve CFG’s emulsifying properties. Herein, an alternative type of enzyme, transglutaminase, was used to prepare conjugates of CFG and sodium caseinate. Additionally, the CFG was partially hydrolyzed by sulfuric acid and its crosslinking pattern with caseinate was evaluated. The interfacial crosslinking degree between caseinate and CFG increased after hydrolysis according to high performance size exclusion chromatography. The equilibrium interfacial tension of CFG hydrolysate-caseinate conjugate was lower than that of CFG-caseinate conjugate as the rearrangement rate of the CFG hydrolysate-caseinate conjugate was higher. The dilatational modulus of CFG hydrolysate decreased from that of CFG.

这项研究对以前的工作进行了补充，在以前的工作中，过氧化物酶已成功用于使玉米纤维胶（CFG）与牛血清白蛋白交联并改善CFG的乳化性能。在本文中，另一种类型的酶，转谷氨酰胺酶，用于制备CFG和酪蛋白酸钠的结合物。另外，CFG被硫酸部分水解，并评估了其与酪蛋白酸盐的交联模式。根据高性能尺寸排阻色谱法，酪蛋白酸盐和CFG之间的界面交联度在水解后增加。CFG水解物-酪蛋白酸盐结合物的平衡界面张力比CFG-酪蛋白酸盐结合物的平衡界面张力低，因为CFG水解物-酪蛋白酸盐结合物的重排率更高。CFG水解产物的膨胀模量比CFG减小。
