| High Light | High Nitrogen Bone Peptone ，Low Ash Biological Grade Peptone ，Excellent Clarity Microbial Culture Peptone | ||
Bone Peptone is a high‑nitrogen, low‑ash, high‑clarity peptone product made from fresh bovine bone through pancreatic enzymolysis, low‑temperature extraction, refining, and spray drying.
It is rich in peptides, amino acids, and trace elements, and is especially suitable for high‑end biological applications such as biopharmaceutical fermentation, microbiological media production, vaccine manufacturing, and diagnostic reagents.
| Item | Description |
|---|---|
| Raw Material Source | Fresh bovine bone (pollution‑free, no spoilage) |
| Production Process | Washing & sterilization → Enzymolysis → Separation → Decolorization & deodorization → Refined filtration → Ultrafiltration → Concentration → Spray drying |
| Process Features | Low‑temperature enzymolysis preserves active components; ultrafiltration ensures clarity; spray drying guarantees stability |
| Applicable Standards | Complies with Chinese Biological Products Main Raw and Auxiliary Materials Quality Control Standard (2000 edition) and enterprise standard Q/SCSH 001‑2025 |
High Total Nitrogen ≥ 14.5% – Provides sufficient nitrogen source to promote rapid microbial growth
Amino Nitrogen ≥ 2.5% – Rich in small peptides and free amino acids, easily utilized by microorganisms
Low Ash ≤ 5.0% – Reduces impurity interference, suitable for precision fermentation
Excellent Clarity – 2% aqueous solution remains clear and precipitate‑free after heating and cooling, ideal for high‑purity media preparation
Stable Biological Performance – Verified with multiple standard strains, supporting tests such as hydrogen sulfide, indole, hemolysis, pigment production, etc.
