Butter is one of the most popular fat-rich dairy products. Butter consists of butterfat, water, and milk proteins and is most frequently manufactured from cow or buffalo milk. It is generally used as a spread and a condiment. It is also used in cooking applications. Manufacture of creamery butter has been confined to the colder regions of the world, where gravity creaming has been successful. Initially, butter was manufactured by using wooden hand churns. But now almost all the butter industries are employing continuous butter making technology.
