Extraction of dye sorghum biocolorant for the dyeing of , a West African soft cheese.

We developed a sustainable method to extract the red biocolorant from dye sorghum leaf sheaths for dyeing , a West African soft cheese. The pigments were extracted using three different solvents: commercial ethanol (method A), (a local liquor distilled from palm wine; method B) and aqueous alkaline solvent (method C). In methods A and B, a pot still was used to distil and collect the solvent for reuse.
