The objective of this study was the validation of selected methods of determining aspartame concent, which was performed based on the parameters constituting elements of the analytical validation procedures. From among the basic criteria of validating the analytical method, the following were applied: selectivity, linearity, precision, uncertainty of measurement, and accuracy. Six methods were taken into consideration: HPLC, three spectrophotometric methods, and two titration methods. HPLC and titration method with perchloric acid were found to be the most precise methods. They were characterized by acceptable values of a relative standard deviation and a HORRAT value
