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
Corn Oligopeptide is a hydrolysed peptide from Zea mays seed protein, not the intact protein and not a botanical extract of the same raw material. Compare source, degree of hydrolysis and MW distribution when substituting.
Compare these related grades before approval:
For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.

Frequently Asked Questions
Which test method should our QC lab expect to reproduce?
HPLC, with the reference standard and calculation basis recorded on the batch certificate.
Which impurity limits are declared?
Moisture and ash are held within the approved specification limits, with heavy metals and microbiology tested on every lot.
Which molecular weight profile applies?
The declared specification is Protein >=80.0% on dried basis; molecular weight mainly below 1,000 Da, and the peptide distribution is reported with the batch.
Which particle size or presentation applies?
98% through 80 mesh
How recent is the representative batch shown?
The batch referenced is LXYM260615; your shipment is released on its own certificate rather than the representative one.
Can I review the COA before I pay?
Yes. Request the current or representative COA and check identity, method, limits and results before approving the purchase order.
What is the usual lead time?
Regular production normally takes 7-15 working days after deposit, depending on stock, volume, testing and customisation requirements.
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.
