Comparative Interaction Mechanisms and Solution Behavior of Cowhide Collagen with Xanthan Gum, Gellan Gum, and Chitosan Under Variable Environmental Conditions.

ABSTRACT: Cowhide collagen (CC) is a valuable by-product of the meat industry with promising applications in food systems; however, its poor viscosity and limited stability restrict its practical use. This study systematically investigated the interactions between CC and three representative polysaccharides-xanthan gum (XG), gellan gum (GG), and chitosan (CS)-under varying concentrations, pH, and ionic strengths. The physicochemical behaviors of the composite systems were evaluated through turbidity, fluorescence spectroscopy, Fourier transform infrared (FTIR) analysis, and rheological measurements. The experimental results revealed a pronounced increase in the turbidity of the GG-CC system, rising from approximately 0.18 ± 0.01 to 2.14 ± 0.01 as the polysaccharide concentration increased, with maxi
