Everything about Tallow totally explained
Tallow is a
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's kept in an airtight container to prevent
oxidation.
Rendered fat obtained from
pigs is known as
lard.
Uses
It is used in animal feed, to make
soap, for
cooking, and as a
bird food. It can be used as a raw material for the production of
biodiesel and other
oleochemicals. Historically, it was used to make tallow
candles, which were a cheaper alternative to wax candles.
Industrially, tallow isn't 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
Hindus (many of whom don't
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.
Tallow is used in the
steel rolling industry to provide the required lubrication as the sheet steel is compressed through the
steel rollers. There is a trend towards replacing tallow based
lubrication with synthetic oils in rolling applications for surface cleanliness reasons.
Tallow can also be used as
flux for
soldering.
Composition
The composition of the fatty acids is typically as follows:
- Saturated fatty acids:
- Monounsaturated fatty acids:
- Polyunsaturated fatty acids:
