New titrimetric and spectrophotometric methods are proposed for the determination of aspartame. N-bromosuccinimide (NBS), acetous perchloric acid and sodium methoxide are used as titrants, employing some internal indicators in a titrimetric assay. NBS-metol-sulphanilamide is used for the indirect spectrophotometric determination of aspartame. The charge-transfer complexes formed between aspartame and quinones, namely, chloranilic acid and chloranil, are explored for their spectrophotometric determination. Experimental conditions and recoveries in commercial samples and foods are reported.
