“…To fulfill the requirements of quality control, several analytical methods have been described to determine saccharin. Included among these are polarography ( , ), gravimetry (), derivative ultraviolet spectrophotometry (), high-performance liquid chromatography (HPLC) ( 3 , − , potentiometry ( − ), and visible spectrophotometry ( − ). However, most of these methods are time-consuming or require expensive equipment and, consequently, are not ideal for routine analysis.…”

A simple, rapid, and sensitive spectrophotometric method for routine analysis of saccharin in commercial noncaloric sweeteners is proposed. This method is based on the reaction of saccharin with tetrachloro-p-benzoquinone (p-chloranil) accelerated by hydrogen peroxide and conducted in an ethanol:acetone (4:1) medium, producing a violet-red compound (lambda(max) = 550 nm). Beer's law is obeyed in a concentration range of 2.05 x 10(-4) to 3.00 x 10(-3) M with an excellent correlation coefficient (r = 0.9998). The detection limit was 1.55 x 10(-5) M, and the effect of interferences on the spectrophotometric measurements was evaluated. The proposed procedure was applied successfully to the determination of saccharin in noncaloric sweeteners. Recoveries were within 99.2-104.3% with standard deviations ranging from to 0.5-1.6%. Results of the proposed method compare very favorably with those given by the high-performance liquid chromatography method recommended by the Food and Drug Administration.
