Manufacturing Process Overview
| Stage | Description |
|---|---|
| Raw material | Fresh bovine hide (no tannery waste), traceable and quarantine certified |
| Cleaning | 10‑15 washes with deionized water; 250 tons water per ton of hide |
| Defatting | Mechanical removal of fat and hair to ensure purity |
| Hydrolysis | 1% multi‑enzyme complex (including flavor enzymes), precise pH/T control |
| Decolorization | Food‑grade activated carbon (13,000 mesh) |
| Desalting & Deashing | Multi‑bed ion exchange → low ash, low heavy metals |
| Sterilization | High‑temperature high‑pressure (HTST) |
| Drying | Spray drying → fine powder, excellent flowability |
| QC | Batch release testing (protein, hydroxyproline, heavy metals, microbiology) |
