Phthalate plasticizers can be contaminated by the environment and are likely to migrate from utensils and containers used in food manufacturing. Phthalates are thought to persist due to phthalate contamination of raw materials, migration from manufacturing tools and containers, and so on. To investigate the residual state of phthalates in distributed foods, the contents of six plasticizers were analyzed by GC-MS: dimethyl phthalate (DMP), diethyl phthalate (DEP), di-n-butyl phthalate (DBP), butyl benzyl phthalate (BBP), di(2-ethylhexyl) adipate (DEA), and di- (2-ethyl hexyl) phthalate (DEHP). The test method was verified for specificity, linearity, limit of detection (LOD), limit of quantitation (LOQ), accuracy, and precision. The approximate limits of the LOD and LOQ were 0.04 mg/L to 0.06 mg/L and 0.12 mg/L to 0.20 mg/L, respectively, and the linearity demonstrated R2>0.99 in the range of 0.2 to 5.0 mg/L. The recovery test was 74∼124%. To assess applicability of the method, 178 commercial food products were monitored. DMP and DEA were not detected, and DEP and BBP were below the quantification limit in the majority of dietary groups. In soybean paste, noodles, gochujang, tea powders, processed grain products, and other processed items, DBP was detected up to 1.16 mg/kg, and DEHP was detected up to 0.67 mg/kg. Dissolution test for each packaging material in the detected foods revealed no packaging material.
