Dibutylhydroxytoluene (BHT) was detected in dried fishes to which it had not been added as a food additive. In order to examine the migration of BHT from the plastic packaging material to the dried fishes, the relationship between the storage conditions (temperature and duration) and the quantity of migration was investigated. Increased quantity of migration was observed at higher temperatures and longer periods of storage.A random survey of foods on the market revealed 2.0-3.6mg/kg of BHT in dry foods and 0.15-1.7μg/cm2 in the plastic wrapping material. BHT was detected more frequently in wrapping with lower gas permeability, namely polyvinilidene chloride, than in other wrapping material.
