A preservative is a substance or a chemical that is added to products such as food, beverages, pharmaceutical drugs, paints, biological samples, cosmetics, wood, and many other products to prevent decomposition by microbial growth or by undesirable chemical changes. Chemical preservation entails adding chemical compounds to the product. Preservative food additives reduce the risk of food borne infections, decrease microbial spoilage, and preserve fresh attributes and nutritional quality.
