Of the retail foods, one of the groups that most commonly contain preservatives are “dry” products: chips, crackers and snack foods, cookies, dry cereals and dry mixes (cake, brownies, and so on).  In a dry food, oxidation of the fat is more likely than  mold or bacterial growth. Dry food has a long shelf life because spoilage organisms are unable to grow on it.
