Hydrolyzed Bovine Collagen Peptide with High Hydroxyproline, Low Moisture, and Molecular Weight Below 3000 Da for Industrial and Food Grade Applications
Bovine Collagen Peptide Containing High Hydroxyproline and Low Moisture with Strict Control for Industrial and Food Grade Applications
1. Product Identity
Hydrolyzed Bovine Collagen Peptide is produced from fresh, quarantine‑certified bovine hides using controlled multi‑enzyme hydrolysis, followed by intensive deashing, decolorization, and spray drying. The product is characterized by high protein content, exceptionally high hydroxyproline, low ash, and a molecular weight strictly below 3000 Da.
