In today's world, modern food manufacturers use different techniques of production and storage to satisfy market requirements. Different additives are used to prevent food deterioration, and one of them is preservatives.

Except for the natural ones, we have artificially created preservatives. Nitrates are used to preserve processed meats like sausages or bacon. Antioxidants prevent the decline of oils and fats. 

Sulfites are used in vegetables, wine and dried fruits. Benzoates prevent salad dressings from souring, and sorbates are used in products like fruit juices and jams.
