Curcumin
Definition
Curcumin is the primary yellow-orange pigment compound found in turmeric, commonly used as an indicator of turmeric quality and, in higher-purity extracted forms, valued for colour and functional applications.
Why It Matters
Curcumin content (typically expressed as a percentage) is a key specification buyers reference when sourcing turmeric, alongside moisture and foreign matter.
Example
A buyer sourcing turmeric powder may specify a minimum curcumin content percentage as part of the product specification.
