Abstract The aim of this study was to explore the effect of combined dietary jerusalem artichoke polysaccharide and alfalfa polysaccharide (m/m = 1:1) on the eating quality of duck meat. The results showed dietary supplementation of 500 mg/kg of plant-derived polysaccharides significantly increased the pH at 24 h postmortem (pH24 h) (P < 0.05), increased the color parameter a* value, and decreased the L* and b* values, indicating improved meat color. In addition, the shear force was reduced by 30.23%, the tenderness was greatly improved, and the degree of lipid oxidation was significantly decreased (P < 0.05). Moreover, low-field nuclear magnetic resonance (NMR) revealed that dietary addition of plant-derived polysaccharides reduced the freeness of water and decreased water loss. Raman spectra showed the content of α-helix was increased, demonstrating improved stability of protein secondary structure. Analysis of volatile flavor compounds showed that the contents of off-flavor compounds such as pentanal and hexanal were significantly decreased.
