Simple spectrophotometric method has been developed for estimation of benzoate salt as preservatives in food. In this method systematic extraction of the benzoate salt from different food products is employed and the concentration of benzoate salt is determined by standard addition method using methanol as a solvent. The wavelength which is λmax 226 nm was selected for estimation of benzoic acid, unionized form of all benzoates salts. The systems obey Beer’s law in the range of 1.5-40 mcg/ml with correlation coefficient of 0.998. Inter-day, intra-day precision and accuracy studies were done as per ICH guidelines. No interference was observed from other food product components.
