Source Journal of King Saud University. Science. Volume 18, No 2. (2006/1426)
Abstract A rapid and simple UV spectrophotometric procedures were applied for the determination of the content levels of some food additives in 29 different beverage samples commercially available in Riyadh local markets. These analytical measurements were undertaken primarily to assess the compliance of content levels of the investigated food additives and their daily intake doses with the permissible levels. The results obtained from this study indicated that the average quantity levels of aspartame, caffeine and sodium benzoate in the analyzed beverages were 246.7 ppm, 18.99 ppm and 16.14 ppm, respectively. In addition, the concentrations of these food additives have been converted into the daily intake doses based on beverages consumption. It was estimated that the mean daily intakes of aspartame, caffeine and sodium benzoate by the adult population of Riyadh city through the consumption of the analyzed beverages were 92.5 mg, 6.3 mg and 6.46 mg, respectively. None of the analyzed beverage samples was found to violate the current legal limits practiced in the Saudi food regulations.
