Description
PEPTIDE INGREDIENT
Oreochromis niloticus Scale — Hydrolysed Collagen Peptide
Tilapia scale collagen is a freshwater source, and that is the commercial point: it carries no marine allergen association and is not exposed to the heavy-metal profile that some buyers screen for in marine raw material.
COA-Backed Specification
| Identity | Oreochromis niloticus (tilapia scale) |
|---|---|
| Plant part | Scale (collagen hydrolysate) |
| Form and colour | Fine white to off-white powder |
| Assay | Protein >=90.0% on dried basis; molecular weight distribution declared per lot |
| Method | HPLC |
| Particle size | 98% through 80 mesh |
| Loss on drying | Within the limits of the approved specification |
| Ash | Within the limits of the approved specification |
| Heavy metals | Within the limits of the approved specification |
| Microbiological limits | Within the limits of the approved specification |
| Shelf life | Two years when stored properly |
Limits shown are the agreed specification. Result values are issued on the batch-specific certificate of analysis.
Buyer Decision Guide
Ask which tissue the collagen came from. Skin, scale and bone give different peptide profiles and different price levels under the same “fish collagen” name.
- Source: tilapia scale, a freshwater species. Declared on the COA.
- Differentiation: no marine raw-material chain, which matters for buyers screening for heavy metals.
- Assay: protein on dried basis, with molecular weight distribution reported per lot.
- Appearance: fine white to off-white powder with a very low odour.
- Solubility: freely water-soluble; solutions are clear at typical dosing.
- Documentation: COA, specification sheet and SDS with each batch.
How This Grade Differs
The existing fish collagen peptide is made from fish skin. This page is the scale-derived freshwater product, which is a different raw-material chain.
Quality and Documentation
Released on a batch certificate covering protein, molecular weight distribution, ash, moisture, heavy metals and microbiology.
Frequently Asked Questions
Is the declared percentage a specification limit or a measured result?
The specification figure is Protein >=90.0% on dried basis; molecular weight distribution declared per lot; the measured result for your lot is reported separately on its COA.
What links the quotation to the delivered material?
The specification figure (Protein >=90.0% on dried basis; molecular weight distribution declared per lot) and the batch number on the COA carry through from quotation to certificate.
How is protein content expressed?
Protein >=90.0% on dried basis; molecular weight distribution declared per lot, on the basis stated on the certificate.
How long can we hold stock before use?
Two years from the manufacture date when the pack stays sealed and dry.
What do you declare for moisture and ash?
Both are released against the limits on the approved specification; the measured result for your lot appears on its COA.
Are you a manufacturer or a trading company?
LongBio is Shaanxi Longsheng Biotechnology Co., Ltd., a direct manufacturer of botanical extracts and functional ingredients integrating R&D, production and export support. Factory review can be arranged by video or an on-site visit.
What is the usual lead time?
Regular production normally takes 7-15 working days after deposit, depending on stock, volume, testing and customisation requirements.
How is the material shipped?
Air and sea freight are both arranged, with the mode chosen against volume, destination and required date. Documents and the HS code are issued with the shipping instructions.
