Explain how commonly used chemicals preserve food
A preservative is a material or chemical that is added to foods, beverages, pharmaceutical medications, paints, biological samples, cosmetics, wood, and a variety of other goods to prevent them from deteriorating owing to microbial development or unfavorable chemical changes. Chemical and physical preservation are the two main forms of preservation. Adding chemical components to a product to preserve it is known as chemical preservation. Refrigeration and drying are two examples of physical preservation. Food additives with preservatives lower the risk of foodborne diseases, prevent microbiological deterioration, and maintain freshness and nutritional quality. Techniques of chemical and physical preservation are occasionally used in conjunction.
Chemical preservatives in foods fall into three categories:
- Benzoates
- Nitrites
- Sulfates
