Chelation of the Collagen Peptide of Seabass (Lates calcarifer) Scales with Calcium and Its Product Development

Seabass (Lates calcarifer) is one of the top farmed and raised fish in Taiwan, scales are main by-product after processing. Fish contain high amounts collagen, which can chelate with minerals enhance mineral absorption human body. Hence, from seabass were enzymatically hydrolyzed to obtain scale collagen peptide (SBSCP). Calcium, most consumed supplement, was chelated SBSCP form SBSCP-Ca. The optimal conditions for chelation a peptide/calcium ratio: 1:1 (w/w), pH 5.0, 50 °C 20 min. conjugated sites carboxyl amino groups based on Fourier transform infrared (FTIR) spectroscopy. Scanning electronic microscope/energy-dispersive X-ray spectroscopy (SEM/EDS) evidently showed alternation SBSCP’s molecular structure increased concentrations metal ions.
