Buyer Decision Guide
Specify Salmon collagen peptide by the declared basis, the delivered form and the certificate of analysis. For this grade the basis is Protein >=90%; average molecular weight below 1,000 Da and the delivered form is Fine white to off-white powder. Confirm the destination market requirements, the intended use category and the required documentation before approval. This material is offered as an industrial raw material for further processing, not as a finished consumer product, and no health or medical claim is made.
- Declared basis and delivered form stated on the specification
- Documentation supplied: batch COA, specification sheet and agreed third-party testing
- Species and origin stated on the certificate; substitution requires written confirmation
- Destination market and intended use to be confirmed at quotation stage
- Samples available for evaluation against your own process
How This Grade Differs
Salmon collagen peptide is listed at protein >=90% and average molecular weight below 1,000 Da. The identity table names salmon as Salmo salar / Oncorhynchus rather than one confirmed species; check the offered-lot species before comparing this grade with cod or other fish collagen peptides.

Frequently Asked Questions
How is Salmon Collagen Peptide Powder quantified?
By Kjeldahl and SEC-HPLC against the specification figure of Protein >=90%; average molecular weight below 1,000 Da.
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.
Can you supply a specimen for identity verification?
A retained sample is kept for each lot and the identity is stated as Salmon (Salmo salar / Oncorhynchus).
How does the material behave in your process?
It is supplied as Fine white to off-white powder at 98% through 80 mesh, so bulk density and flow are confirmed against your process before the first order.
How long can we hold stock before use?
Two years when stored properly from the manufacture date when the pack stays sealed and dry.
