Preparation optimization, structural characterization, stability and promoting calcium absorption mechanism of sturgeon cartilage peptide-calcium chelates
The preparation process of sturgeon cartilage peptide (SCP)‑calcium chelates (SCP-Ca) was optimized in this work, its structure, stability and promoting calcium absorption mechanism were explored. The optimum conditions for preparing SCP-Ca with Ca amount of 44.47 ± 0.87 mg/g were 50 min, 40 °C, pH of 8 and a peptide-t...
