|---|---|---|---|
Hydrolyzed Bovine Collagen Peptide is manufactured from fresh, traceable bovine hides using a multi‑stage enzymatic process followed by ion exchange and spray drying. The product is defined by its high protein purity, elevated hydroxyproline content, extremely low ash, and tightly controlled molecular weight distribution. No industrial or tannery by‑products are used.
| Parameter | Test Result | Reference Method |
|---|---|---|
| Protein (dry basis, N×5.79), % | 97.56 | GB 5009.35 |
| Hydroxyproline (dry basis), % | 9.86 | GB/T 9695.23 |
| Moisture, % | 4.56 | GB 5009.3 |
| Ash, % | 0.45 | GB 5009.4 |
| pH (1% solution) | 6.56 | GB 5009.237 |
| Molecular weight (in‑house) | <3000 Da | HPLC‑GPC |
