If it weren't for food preservatives, we couldn't enjoy many of the great foods the world has to offer. Common antimicrobial preservatives include sodium nitrate, calcium propionate, disodium EDTA, potassium sorbate, sodium benzoate, and sulfites.
There is a wide variety of food preservatives used by cooks and food manufacturers to extend shelf life and improve storage of both cooked and raw foods. Many natural preservatives, like salt and sugar, are often used in preserving canned fruits, processed meats as well as various types of canned or jarred vegetables.
