Butter:
It is made by separating thin cream from skim milk, ripening the thin cream and stirring. The biggest difference between butter and cream is the composition, and the fat content of butter is higher. High-quality butter is light yellow in color, even and delicate in texture, with no moisture oozing from the cut surface and fragrant in smell. Butter can be divided into raw butter (made directly from raw milk), superfine butter (only pasteurized raw milk or cream) and refined butter (partially frozen milk). In taste, it can also be divided into original flavor, semi-salt and salted butter. Butter is divided into edible butter and lubricating butter, which is also called grease and is a kind of lubricating oil.
