摘要：The purpose of this study was to investigate the effects of interactions between gut microbiota and soy hull polysaccharides (SHPs) on the air-liquid interfacial activity. SHPs could be used as an energy source for gut microbiota metabolism, and within a certain concentration range, the acid production of gut microbiota had a SHP concentration dependence. In the process of interfacial adsorption, the polysaccharide concentration was negatively correlated with interfacial tension, and the simulated intestinal fluid viscosity and dilational modulus were positively correlated. The low concentration of SHPs had a greater impact on the diversity and structural composition of gut microbiota. 0.5% SHPs had a better effect on the proliferation of Lactobacillus. The gut microbiota degraded SHPs involved in the regulation of interfacial activity, which provided a new theoretical foundation for the utilization and absorption of polysaccharides in the intestine in vitro.
