Bovine Collagen Peptide Containing High Hydroxyproline and Low Moisture with Strict Control for Industrial and Food Grade Applications
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.
| Parameter | Standard | Typical Value | Method |

| Ash, % | ≤2 | 0.45 | GB 5009.4 |
| pH (1% solution) | 5.0 – 7.0 | 6.56 | GB 5009.237 |
| Molecular weight (Da) | Not regulated | <3000 (in‑house) | HPLC‑GPC |
| Range (Da) | Percentage | Purpose of Control |
|---|---|---|
| >5000 | 3.3% | Minimize high‑MW fraction |
| 1000 – 5000 | 32.5% | Balanced bioavailability |
| 150 – 1000 | 56.4% | Dominant low‑MW peptides |
| ≤150 | 7.8% | Free amino acids |
>96% of peptides below 5000 Da – ensures rapid solubility and consistent performance.
