COA-BACKED PLANT PROTEIN
Corn Protein Powder for Plant-Based Formulation
Corn Protein Powder is supplied for B2B plant-based nutrition, beverage and food projects. Specification is defined by protein content on a dry basis, process route and the physical parameters that control dispersion in your formulation.

Buyer Decision Guide
Plant proteins are specified by protein content basis (as-is or dry basis), process route (isolate, concentrate or flour), particle size and dispersibility. Confirm all four before comparing quotations from different suppliers.
- Confirm whether protein is declared as-is or on a dry basis
- Check the process route: flour, concentrate or isolate
- Review dispersibility, flavour and off-note profile
- Confirm allergen declarations for your destination market
How This Grade Differs
Corn Protein Powder differs from other plant protein sources in amino acid profile, flavour and functional behaviour, and from the isolate or concentrate form of the same raw material. Compare on protein basis and process route rather than on the ingredient name alone.
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
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.
How is protein content expressed?
60.0% on dry basis, on the basis stated on the certificate.
How does the material behave in your process?
It is supplied as Fine light-yellow to yellow powder at 98% through 80 mesh, so bulk density and flow are confirmed against your process before the first order.
What links the quotation to the delivered material?
The specification figure (60.0% on dry basis) and the batch number LXYM260421 carry through from quotation to certificate.
Which test method should our QC lab expect to reproduce?
HPLC, with the reference standard and calculation basis recorded on the batch certificate.
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.
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.
Can you produce to our own specification or packing?
Alternative assay targets, particle size, packing and private-label requirements are reviewed case by case, subject to production feasibility and a revised written specification.
