description Summary In this study, we modified the soy protein isolate (SPI) by glycosylation technology, tracked and detected its gelling properties in a trial‐box, which simulated the ocean shipping environment, then determined the optimised parameters for glycosylation modification, including humidity, temperature, reaction time, and the amount of polysaccharide added. The gelling stability of the glycosylated SPI increased significantly compared with the non‐modified SPI. The physicochemical properties of glycosylated SPI and non‐modified SPI (degree of glycosylation and sulfhydryl groups) were measured to correlate their effects on the gel strength of glycosylated SPI gels. With an analysis of gel microstructure images measured by a scanning electron microscope, we further verified the formation of the macromolecular complex in glycosylated SPI during glycosylation; the microscopy also revealed a relationship between microstructure and gelling properties of SPI.
