Cream is a dairy product that is composed of the higher-butterfat layer skimmed from the top of raw milk before homogenization. In the raw milk, over time, the lighter fat rises to the top. In the industrial production of cream this process is accelerated by using centrifuges called "separators". In many countries, cream is sold in several grades depending on total butterfat content. Cream can be dried to a powder for shipment to distant markets.
Cream produced by cattle (particularly Jersey cattle) grazing on natural pasture often contains some natural carotenoid pigments derived from the plants they eat; this gives the cream a slight yellow tone, whence the name of the yellowish-white colour cream. Cream from cows fed indoors, on grain or grain-based pellets, is white.
