Abstract

This study aimed to investigate the mechanism of Na⁺/Ca²⁺-induced soy hull polysaccharide (SHP) migration in the mucus layer. The viscosity, potential, microstructure, SHP migration, and metabolite migration were analyzed. The results showed that Na⁺ had little effect on the viscosity of polysaccharides, while Ca²⁺ increased the viscosity of polysaccharides. Na⁺ and Ca²⁺ promoted the migration of SHP particles by reducing the zeta potential, while they decreased the migration of SHP chyle particles by increasing the aggregation. SHP was fermented by gut microbiota to produce a large number of short-chain fatty acids (SCFAs). Compared with Ca²⁺, Na⁺ increased the migration of total SCFAs in the mucus layer. The high-Na⁺/Ca²⁺ mucus internal environment had a specific effect on the transport of nutrients in the intestine.

Keywords: Gut microbiota; Ion; Migration; Soy hull polysaccharide.
