Abstract

In a rapid colorimetric method for the determination of aconitic acid in sorgo juice, the acid is extracted from clarified starch-free juice with 2-butanone after lowering the juice pH to 1.3. One extraction re- layer, produce a purple colour which is read on a moves 99% of the aconitic acid. Othu organic acids, at the level found in sorgo juice, do not interfere with color development. Acetic anhydride and ridine, when added to an aliquot of the 2-butanone layer, produce a purple color which is read on a spectrophotorneter at 550 m.
