Buyer Decision Guide
This material is defined by the tomentose pummelo peel rather than by generic citrus peel. Confirm the peel part, the immature-fruit harvest stage and the ratio definition before approval.
- Confirm the tomentose pummelo species
- Check peel part and harvest stage
- Compare bitterness and aroma between lots
- Confirm TLC identity and moisture limits

How This Grade Differs
Exocarpium Citri Grandis is not interchangeable with orange peel, tangerine peel or grapefruit peel. The species and peel part differ, which changes aroma, bitterness and the resulting specification.
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.
