Buyer Decision Guide
Peptides are specified by source, degree of hydrolysis and molecular-weight distribution. Confirm the protein content basis, the assay method and the MW cut-off, because two products described by the same name can behave very differently in solubility and taste.
- Confirm the source material declaration
- Check protein content and the assay method
- Review molecular-weight distribution data
- Confirm solubility, taste and hygroscopicity for your format
How This Grade Differs
Sturgeon Collagen Peptide is hydrolysed from Acipenser skin collagen and is listed at protein >=90.0% on a dried basis. Compare the skin source, peptide profile and current batch documents with the linked sturgeon-bone grade before substitution.
Compare these related grades before approval:
For a substitution review, compare animal source tissue, dried-basis protein content, peptide specification, analytical method and the current offered-batch COA.

Frequently Asked Questions
Which molecular weight profile applies?
The declared specification is Protein >=90.0% on dried basis; low-molecular-weight peptide fraction, and the peptide distribution is reported with the batch.
Which test method should our QC lab expect to reproduce?
HPLC, with the reference standard and calculation basis recorded on the batch certificate.
What physical form does Sturgeon Collagen Peptide Powder ship in?
Fine white to off-white powder, milled to 98% through 80 mesh.
Which impurity limits are declared?
Moisture and ash are held within the approved specification limits, with heavy metals and microbiology tested on every lot.
How should the material be stored after arrival?
Two years when stored properly. Keep the pack sealed; moisture uptake is the main risk for this grade.
Which documents come with the shipment?
Batch COA, specification sheet, agreed third-party testing where required, commercial invoice, packing list, certificate of origin and transport documents. The exact set is confirmed against the product and destination market.
Can I get a sample before placing the order?
Yes. An evaluation sample is normally available before a formal order. Sample quantity, courier account and destination are confirmed at the time of request.
What packing options are available?
Standard packing is a sealed food-grade inner liner inside an export carton or fibre drum. Pack size, labelling and private-label artwork are agreed in the written specification.
