Buyer Decision Guide
Adzuki is specified by seed identity and ratio. Confirm whether your process requires a decolourised or standard grade, and check dispersion and moisture behaviour before approval.
- Confirm species rather than generic ‘red bean’
- Check colour and dispersion behaviour
- Compare TLC identity and moisture limits
- Confirm whether a low-colour grade is needed
How This Grade Differs
Adzuki bean is a distinct species from white kidney bean and mung bean, with different colour and extractable profile. Specifying the species keeps the purchasing definition and any future substitution review objective.
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.
