Food-grade phosphorylation enhances calcium binding in salmon peptides: Structural insights and bone health improvement for functional foods.
Phosphorylated salmon bone collagen peptides (P-CP) were developed via hydrolysis and food-grade sodium tripolyphosphate modification, resulting in a peptide-loaded phosphorus content of 334.3 mg/100 g, exhibiting high calcium-chelating capacity (91.21%). Structural analyses (FTIR, XRD, UV-Vis, fluorescence) confirmed...
