Stage	Critical Control Point
Raw Material Selection	Only fresh bovine hide / fish skin; no tannery waste. Washed 10‑15 times with 250 tons of deionized water per ton of raw material.
Enzymatic Hydrolysis	1% multi‑enzyme complex (including flavor enzymes), precise pH & temperature control, MW controlled around 3000 Da.
Decolorization & Purification	Food‑grade activated carbon (13,000 mesh) + multi‑bed ion exchange to remove salts and heavy metals.
Sterilization & Drying	High‑temperature high‑pressure sterilization + spray drying; no secondary contamination.
Quality Control	Every batch tested for hydroxyproline, protein, heavy metals, microorganisms; COA issued.
