Studies on the Separating Methods of Dibutylhydroxytoluene and Butylhydroxyanisole from Foods

Abstract

Steam distillation and extractions with several kinds of solvents were investigated as the separating method of dibutylhydroxytoluene (BHT) and butylhydroxyanisole (BHA) from fatty foods. The results obtained are as follows.
1. The method of steam distillation is available only for lower fatty foods.
2. n-Hexane-acetonitrile system extraction is recommended for practical use for high fatty foods.
3. For the concentration of solvent containing BHT or BHA, Kuderna-Danish concentrator is available.
4. BHT and BHA are separated easily from each other by alumina column.
