Peanut butter is a food paste made from ground dry roasted peanuts, which is sold as either “crunchy” or “smooth”/”creamy” variety. Major consumer-brand peanut butter contains hydrogenated vegetable oil to stabilize it and prevent oil separation, salt to prevent spoilage, and dextrose or other sweeteners to enhance flavor. Peanut butter marketed as natural or organic might only contain peanuts and salt. Although some organic and natural varieties use palm oil instead of hydrogenated vegetable oil to prevent oil separation. It is popular in North America and The Netherlands, where it is used mainly as a sandwich spread, and a key ingredient in the peanut butter and jelly sandwich, as well as peanut butter flavored chocolate bars. Peanut butter may also be added to desserts such as cakes and biscuits. The United States and China are leading exporters of peanut butter.
