Description
COA-BACKED PEPTIDE INGREDIENT
Walnut Peptide from Juglans regia kernel protein
Walnut Peptide is supplied as a hydrolysed, low-molecular-weight peptide for B2B nutrition, beverage and supplement projects. Specification is defined by source material, protein content and molecular-weight distribution.

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
Walnut Peptide is a hydrolysed peptide from Juglans regia kernel 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
Is the declared percentage a specification limit or a measured result?
The specification figure is Protein >=70.0% on dried basis; low-molecular-weight peptide fraction; the measured result for your lot is reported separately on its COA.
How is appearance checked?
Fine light-cream powder, compared against a retained sample from the approved batch.
Can the COA be matched to the lot you ship?
Yes. The certificate is issued for the shipped lot, which is the batch LXHT260512 referenced on the specification.
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 long can we hold stock before use?
Two years when stored properly from the manufacture date when the pack stays sealed and dry.
What is the minimum order quantity?
The regular MOQ is typically 1 kg. An evaluation sample of 10-20 g can usually be arranged before a formal order, subject to stock.
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.
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.
