Abstract:A method of sample preparation and preparation of standards by standard addition method for the determination of benzoic acid in flavours was proposed. The chromatography was developed on the polyamide film plate by the linear ascending. The migration distance of solvent was 10 cm. This method has high sample throughput at low operating costs without any large equipment and special reagent. This method is suitable for determination of sorbic acid without modification.
Keywords:TLC  Flavour  Benzoic acid  Sample preparation  Standard additions method
