Sodium benzoate used as a preservative in food 
Sodium benzoate is a preservative commonly used in fruit pies, jams,
beverages, salads, relishes, and sauerkraut—foods that have an acidic pH. It
also naturally occurs in and some spices such as cloves and cinnamon. Soft
drinks are the number one source of sodium benzoate in the diet.
As chemical preservatives, sodium benzoate is frequently used in processed
foods to prevent the growth of bacteria, yeast, or other unwanted
microorganisms that could spoil your food. When sodium benzoate is
combined with water, benzoic acid is produced. Benzoic acid is the active form
of the preservative—the form that protects foods.
