Abstract

One of the most compelling reasons for food analysis is to ensure that it is safe for both consumers and producers. Sodium benzoate is a widely used preservative that can be found in many foods and beverages. The quantitative analysis was done by using a calibration curve method, distilled water is used for preparing standard and sample solutions and the scanning was done at 254 nm. The concentration of sodium benzoate in various soft drinks were calculated and studied. According to the FDA the acceptable concentration of Sodium benzoate is 0.1% and under WHO guidance the daily intake of Sodium benzoate is 5 mg/kg of body weight. The proposed study found that the concentration of Sodium benzoate varies from the acceptable concentration.
