Structure and properties
Butter is made from the cream of animal milk, especially cow’s milk. Goat butter and sheep butter are less commonly used. Butter is spreadable and has a light yellow to yellow color. Over 20 liters of cow’s milk are needed to produce one kilogram of butter. Butter is a purely natural product that contains no additives. It consists mainly of milk fat (lipids), i.e. triglycerides with saturated and unsaturated fatty acids and cholesterol. It also contains water, minerals (e.g. calcium) and vitamins (e.g. vitamin A, vitamin D, vitamin E). Carbohydrates, lactose and protein is present only in small quantities. Butter quickly becomes liquid when heated. The melting point is about 33°C.
