How Much Curcumin Should Turmeric Have?
Curcumin content varies by turmeric origin; here are the typical Indian ranges and how to specify them.
How much curcumin should turmeric have?
It depends on origin. Alleppey-type finger turmeric runs 4-6% curcumin, Erode 2.5-3% and Nizamabad bulb 1.5-2.25%. Higher curcumin commands a premium, so specify a minimum and test it on arrival.
Curcumin by turmeric origin
| Type | Curcumin |
|---|---|
| Alleppey-type finger | 4-6% |
| Erode | 2.5-3% |
| Nizamabad bulb | 1.5-2.25% |
Specifying curcumin correctly
Curcumin is the active that nutraceutical and colour buyers pay for, so it belongs in the contract as a tested minimum percentage, not a claimed origin name. Alleppey-type sits at the top of the range; Nizamabad bulb is grown for volume and sits lower.
Note the naming trap: "Alleppey finger" is a traded grade, not a geographical indication. The Alleppey GI is green cardamom. Buy on the tested curcumin figure rather than on the grade label alone.
Frequently asked
Is high-curcumin turmeric always better?
For colour and nutraceutical use, higher curcumin is worth more. For general culinary use it may not justify the premium. Match the specified minimum to the end use.
