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
Coix Seed 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.
