'''Tallow''' is a [[rendering (industrial)|rendered]] form of [[beef]] or [[mutton]] [[fat]], processed from [[suet]]. It is solid at room temperature. Unlike suet, tallow can be stored for extended periods without the need for [[refrigeration]] to prevent [[decomposition]], provided it is kept in an airtight container to prevent [[oxidation]].
Rendered fat obtained from [[pig]]s is known as ''[[lard]]''.
== Uses ==
It is used in animal feed, to make [[soap]], for [[cooking]], and as a [[Birdfeeding|bird food]]. It can be used as a raw material for the production of [[biodiesel]] and other [[oleochemical]]s. Historically, it was used to make tallow [[candle]]s, which were a cheaper alternative to wax candles.
Industrially, tallow is not strictly defined as beef or [[mutton]] fat. In this context, tallow is animal fat that conforms to certain technical criteria, including its [[melting point]], which is also known as [[titre]]. It is common for commercial tallow to contain fat derived from other animals, such as pigs.
Amid concerns in the 1990s over high [[cholesterol]] content, and concern from [[Hinduism|Hindus]] (many of whom do not [[taboo food and drink#Cows|consume food derived from beef]]) and [[vegetarians]] of inadequate labelling, [[McDonald's]] [[french fries]] were cooked in a mixture 93% beef tallow and 7% [[cottonseed oil]].<ref>Schlosser, Eric (2001). ''Fast Food Nation: The Dark Side of All-American Meal''. Houghton Mifflin. ISBN 0-395-97789-4</ref>
Tallow is used in the [[steel]] rolling industry to provide the required lubrication as the sheet steel is compressed through the [[steel roller]]s. There is a trend towards replacing tallow based [[lubrication]] with synthetic oils in rolling applications for surface cleanliness reasons.<ref>[http://www.patentstorm.us/patents/4891161-description.html Cold rolling mill lubricant - US Patent 4891161<!-- Bot generated title -->]</ref>
Tallow can also be used as [[flux (metallurgy)|flux]] for [[soldering]].<ref>[http://www.fantasyinglass.com/SiteDoc/flux.html Hey Flux<!-- Bot generated title -->]</ref>
Tallow is also the primary ingredient in Proofide, a leather dressing made especially for Brooks leather bicycle saddles, in combination with cod oil, vegetable oil, paraffin wax, beeswax, and citronella oil.
