What turmeric and curcumin are
Curcuma longa — ขมิ้นชัน in Thai — is the rhizome behind both the culinary spice and the curcuminoid extract category. 'Turmeric' usually refers to the whole dried rhizome or its powder; 'curcumin' refers to the concentrated curcuminoid fraction, typically 95% curcuminoids by specification.
The real problem is absorption
Curcumin is poorly water-soluble, rapidly metabolised and poorly absorbed in its native form. That single fact is why the category has fragmented into dozens of branded delivery systems — phospholipid complexes, micellar dispersions, cyclodextrin inclusions, solid dispersions and particle-size engineering. Competing on curcuminoid percentage alone is a commodity race; competing on demonstrated delivery is not.
- Raw 95% curcuminoid extract is a globally traded commodity with thin margins
- Value concentrates in bioavailability, stability and clean-label delivery
- Beverage and clear-liquid applications remain technically difficult and underserved
Sourcing reality
Turmeric is one of the most adulteration-prone botanicals in trade, including synthetic curcumin substitution and colourant contamination. Origin verification and isotopic or chromatographic authenticity testing are standard precautions for buyers who need a defensible supply chain.
Processing considerations
- Native curcumin has very low aqueous solubility — delivery-system design is the primary value lever.
- Curcumin is light- and pH-sensitive; colour shift is an early indicator of degradation.
- Strong pigment and bitterness constrain clear-beverage and neutral-taste applications.
- Authenticity testing should screen for synthetic curcumin and non-permitted colourants.

Frequently asked
What is the difference between turmeric and curcumin?
Turmeric is the whole rhizome or its powder; curcumin is the concentrated curcuminoid fraction extracted from it, usually around 3% of the raw rhizome.
Why is curcumin bioavailability such an issue?
Curcumin is poorly water-soluble and rapidly metabolised, so unformulated curcumin reaches the bloodstream at very low levels. Delivery systems exist to address this.
What is turmeric called in Thai?
ขมิ้นชัน (khamin chan).
