Curcumin Extraction Plant

Curcumin is the main biologically active phytochemical compound of Turmeric. Curcumin is extracted from the dried root of the rhizome Turmeric (Curcuma Longa) by solvent extraction. The process of extraction requires the raw material to be ground into powder, and washed with a suitable solvent that selectively extracts colouring matter. This process after distillation of the solvent yields an oleoresin with colouring matter content and other resinous extractives. The oleoresin so obtained is subjected to further washes using selective solvents that can extract the curcumin pigment from the oleoresin. This process yields a powdered, purified food colour, known as curcumin powder.
