A simple and systematic determination method was developed for 11 kinds of organic polybasic acids (OPBA) and their salts contained in various foods. Outline of the procedure is as follows: organic polybasic acids and their salts were extracted with water from sample, purified by ion-exchange column, prepared their derivatives with TMS (trimethyl silylation) reagent and then determined by gas liquid chromatography. Recoveries of them at 0.5 mg/g spikage levels in juice, jam and edible ice were within the range of 72.9-101.8%. Detection limit by this method was 0.01mg/g and it takes only two hours for this whole procedures. The reconfirmation of them contained in some foods was carried out by thin layer chromatography.
