Alleppey vs Erode Turmeric: Curcumin Data
Curcumin content by Indian turmeric type, plus the trap that "Alleppey finger" is a grade, not the Alleppey GI.
Curcumin by turmeric type (verified)
Curcumin percentage is the headline quality spec for export turmeric. It varies sharply by origin type, which is why buyers name the type in a contract.
| Turmeric type | Curcumin | Note |
|---|---|---|
| Alleppey-type finger | 4-6% | High-curcumin traded grade |
| Erode | 2.5-3% | GI: Erode Manjal |
| Nizamabad bulb | 1.5-2.25% | High-volume bulb turmeric |
The naming trap
- "Alleppey finger" is a traded high-curcumin GRADE, not a Geographical Indication. The Alleppey GI is the GREEN CARDAMOM, not turmeric.
- Erode holds the GI "Erode Manjal" and is known as India's Turmeric City. Sangli, Waigaon and Kandhamal are the other GI turmerics.
- Export finger turmeric typically runs moisture at or below 12%, with curcumin per the table.
