tallow

n. hard fat obtained from animal products (used to make candles, soap, etc.); fatty substance obtained from plants

Tallow is also a component of the WiX installer software. Tallow is rendered mutton, beef or other bovine fat, processed from suet. (Rendered fat obtained from pigs is known as lard.)The tallow derived from beef is called stearin. 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. It is used in animal feed, to make soap, for cooking, as a bird food, and was once used for making candles. It can be used as a raw material for the production of biodiesel and other oleochemicals.
