Buyer Decision Guide
Coix is specified by seed identity and ratio. Because the grain carries starch and lipid, confirm carrier level, dispersion behaviour and moisture limits before approving the specification.
- Confirm seed identity and ratio definition
- Check starch and lipid-related dispersion behaviour
- Compare moisture limits on the COA
- Confirm the particle size suits dry blending
How This Grade Differs
Coix seed differs from coix root and from coix seed hull materials, and it is distinct from barley and rice derivatives. Specifying seed identity prevents substitution between these grain streams.
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.
