Cream
<p ><b>Cream</b> is a <a href="http://en.wikipedia.org/wiki/Dairy_product" title="Dairy product" >dairy product</a> that is composed of the higher-<a href="http://en.wikipedia.org/wiki/Butterfat" title="Butterfat" >butterfat</a> layer skimmed from the top of <a href="http://en.wikipedia.org/wiki/Milk" title="Milk" >milk</a> before <a href="http://en.wikipedia.org/wiki/Homogenization_(chemistry)" title="Homogenization (chemistry)" >homogenization</a>. In un-homogenized milk, over time, the lighter fat rises to the top. </p>
<p>
In the industrial production of cream this process is accelerated by using <a href="http://en.wikipedia.org/wiki/Centrifuge" title="Centrifuge" >centrifuges</a> called "separators". In many countries, cream is sold in several grades depending on the total butterfat content. Cream can be dried to a powder for shipment to distant markets.</p>
<p>
Cream skimmed from milk may be called "sweet cream" to distinguish it from whey cream
skimmed from <a href="http://en.wikipedia.org/wiki/Whey" title="Whey" >whey</a>, a <a href="http://en.wikipedia.org/wiki/By-product" title="By-product" >by-product</a> of <a href="http://en.wikipedia.org/wiki/Cheese" title="Cheese" >cheese</a>-making. Whey cream has a lower fat content and tastes more salty, tangy and "cheesy".<sup id="cite_ref-0" class="reference" ><a href="http://en.wikipedia.org/wiki/Cream#cite_note-0" >[1]</a></sup></p>

Cream produced by <a href="http://en.wikipedia.org/wiki/Cattle" title="Cattle" >cattle</a> (particularly <a href="http://en.wikipedia.org/wiki/Jersey_cattle" title="Jersey cattle" >Jersey cattle</a>) grazing on natural <a href="http://en.wikipedia.org/wiki/Pasture" title="Pasture" >pasture</a> often contains some natural <a href="http://en.wikipedia.org/wiki/Carotenoid" title="Carotenoid" >carotenoid</a> pigments derived from the <a href="http://en.wikipedia.org/wiki/Plant" title="Plant" >plants</a> they eat; this gives the cream a slight yellow tone, hence the name of the yellowish-white color, <a href="http://en.wikipedia.org/wiki/Cream_(color)" title="Cream (color)" class="mw-redirect" >cream</a>. </p>
