This study was conducted to investigate the safety status of gasket of glass bottle being used for the Bulgogi sauce. The content of plasticizers in the gasket and their migrated amounts into Bulgogi sauce were determined. Among the plasticizers analyzed, only di-isodecyl phthalate (DIDP) was detected in the range between 30.6 and 35.9% from 6 samples. None of the plasticizers was detected in the sauce. Therefore, it can be concluded that the safety status of the gasket tested met the requirement of limit values as prescribed for the migration test of food packaging utensils, containers and packages of the Korea Food Code.
