How is butter extracted?

It is extracted from milk or whipped cream, and the milk or whipped cream is stirred violently, so that the protein membrane of the butterfat globules is broken and the butterfat flows out of the globules. After losing protein's protection, the fat and water separated, floated slowly, gathered together and turned pale yellow. At this time, the upper layer of fat is separated, salt is added, and water is squeezed out, which becomes daily edible butter.

Huns are the earliest people who processed edible butter in the world. Butter, also known as cream and cream, is made by separating thin cream from skim milk, ripening and stirring the thin cream. 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.

The historical and cultural records of butter can be traced back to ancient times five or six thousand years ago, and can be found in some ancient Indian books and works of ancient Greek writers. However, at that time, people did not regard butter as food, but as medicine, cosmetics and sacrifices to the gods. Butter was first invented by a few people living in grasslands and cold north. As a kind of food, it has a solemn position, because it is scarce and precious.
