Detection of the presence of BHA by a rapid spectrofluorimetric screening procedure.

A rapid screening procedure for detecting BHA in miscellaneous materials such as foodstuffs is presented. It is based on the sensitive fluorimetric detection of BHA following its isolation from complex sample matrices by steam distillation. Because of the sensitivity achieved, only small samples are required and time-consuming extractions of the antioxidant are eliminated. The rationale for the procedure, and some of its limitations, are discussed.
