Detection and Analysis of Sodium Benzoate in Food Samples: A Study on its Presence and Potential Health Impacts

Abstract The objective of this research is to determine the presence of sodium benzoate in different food samples using a simple detection method with minimal cost. Sodium benzoate is a widely employed food preservative which is capable of extending the shelf life of foods, but can exert potential health risks if ingested in large amounts. The process of detection involved the addition of 0.1 M NaOH to diluted food samples, monitoring the appearance of color or precipitation changes as possible indicators of sodium benzoate. The method's simplicity and low cost make it useful for rapid and accurate assessments of food safety. Out of all samples tested, only the tomato ketchup was able to produce a significant coloras change which indicated the presence of sodium benzoate. The other food samples failed to show any such reaction which suggests that the preservative is not present in those samples. This study illustrates how strong the abovementioned method is in the detection of sodium benzoate suggesting it be incorporated in food quality control mechanisms whose purpose is to ascertain food safety. It also stressed the need to check the concentration of sodium benzoate in processed foods for its possible health hazards associated with its use. These conclusions provide a basis for developing innovative approaches to the economical measurement of food additives, and with the regulation of food additives. This study helps improve public health by ensuring the safe use of processed foods.
