How curcumin is extracted from termeric powder?

Curcumin is extracted from turmeric powder through a process called solvent extraction. In this method, turmeric powder is mixed with a solvent, typically ethanol or methanol, which dissolves the curcumin. The mixture is then filtered to remove the solid residue, and the solvent is evaporated to yield concentrated curcumin. Alternative methods include supercritical fluid extraction and cold pressing, but solvent extraction remains the most common approach.
