Improved method for the estimation of parasorbic acid in sorbic acid

A simple method for determining parasorbic acid (I) in sorbic acid (II), suitable for use down to levels of 0.5 mg/kg, is described. The parasorbic acid is extracted from aqueous potassium sorbate with dichloromethane and determined by gas chromatography using a flame ionisation detector.
