Abstract
Benzoic acid (BA) is typically found in natural food; therefore, naturally occurring BA must be distinguished from added BA preservatives. In this study, we investigated BA levels in 100 samples of fruit products and their fresh fruits as raw materials using dialysis and steam distillation approaches. BA was detected in the range (minimum-maximum) of 2.1-1380 μg/g and 2.2-1950 μg/g in dialysis and steam distillation, respectively. Steam distillation indicated higher BA levels than dialysis.
