Buyer Decision Guide
Roselle is specified by calyx identity, anthocyanin level and the analytical method. Because UV anthocyanin results are method-dependent, compare grades only against the same method before approval.
- Confirm calyx rather than whole-flower material
- Compare anthocyanin results against the same method
- Check colour hue and pH sensitivity
- Confirm light and heat stability for your process
How This Grade Differs
Roselle calyx is a distinct species from other hibiscus materials and from bilberry or grape anthocyanin sources. Colour hue, method and plant part all affect the purchasing definition.
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.
