Curcumin is the bright, golden-yellow pigment found in turmeric. The use of turmeric to colour and flavour food has been a common practice for centuries in many cultures. Along with the bright yellow colour, it also imparts a characteristic flavour to food. Curcumin is extracted from the dried tuber or rhizome of the turmeric plant, Curcuma longa, by grinding the tuber followed by an extraction process. The extraction process has the flexibility to retain or remove the flavour. Curcumin is an oil soluble pigment, but can be made water soluble by emulsification technology. Powder formulations are also produced by spraying onto a suitable carrier.
