Manufacturing & Quality Control

The production of high-purity hydrolyzed collagen peptides begins with the selection of raw materials from bovine hide, fish skin, or porcine sources that are certified as BSE/TSE-free and halal-compliant. The process involves acid or alkaline pretreatment to remove non-collagenous proteins, followed by controlled enzymatic hydrolysis using food-grade proteases at optimized pH and temperature. After hydrolysis, the peptide solution undergoes ultrafiltration through membranes with 10 kDa and 5 kDa cutoffs to remove high-molecular-weight fragments and impurities. Final purification is achieved through activated carbon decolorization, ion-exchange demineralization, and sterile filtration through 0.2 μm filters. Each batch is subjected to third-party testing by ISO 17025 accredited laboratories for molecular weight distribution, amino acid profile, heavy metals, and microbiological safety.
