A method is presented for the precise and accurate determination of sodium saccharin in chewing gum utilizing high pressure liquid chromatography. The sodium saccharin is extracted into a biphasic solvent system and quantitated by the internal standard method. The procedure presented exhibits a percent recovery of 101.3% with a standard deviation of 2.6%. Results of the analysis of five different flavors of two commercial brands of sugarless chewing gum indicate a range of 79% to 116% of label claim. No evidence of chemical degradation of the sodium saccharin was found.
