This study was carried out to propose a simple method for the extraction of seven tar dyes such as tartrazine, sunset yellow FCF, amaranth, erythrosine, allura red, brilliant blue FCF and indigo carmine using aminopropyl amine cartridge and to determine the content of the dyes in candies, soft drinks, ice bars and okchuns produced in Korea. The tar dyes were simultaneously analyzed by reverse phase high performance liquid chromatography(HPLC). The recovery rates of the dyes ranged from 65.8% to 99.6%. The contents of the dyes in candies, soft drinks, ice bars and octhuns were N.D.-50.1 mg/kg, N.D.-49.9 mg/kg, N.D.-56.0 mg/kg and N.D.-867.3 mg/kg, respectively. The types of the dyes used most frequently for candies, soft drinks and ice bars were tartrazine, brilliant blue and amaranth, respectively. Of the samples, tartrazine was used frequently, and indigo carmine was not used at all.
