Fat is a poor conductor of heat; therefore, it allows the heat that the animal produces to remain in their body for a longer period of time. [5] [6] Fat is also used by animals for the storage of energy. The type of fat that is used for energy storage is known as adipose tissue. [7]
In this context, tallow is animal fat that conforms to certain technical criteria, including its melting point. Commercial tallow commonly contains fat derived from other animals, such as lard from pigs, or even from plant sources. Tallow consists mainly of triglycerides (fat), whose major constituents are derived from stearic and oleic acids.
An animal product is any material derived from the body of a non-human animal or their excretions. [1] Examples are meat, fat, blood, milk, eggs, honey, and lesser known products, such as isinglass, rennet, and cochineal. [2] The word animals includes all species in the biological kingdom Animalia, except humans.
Animal fat contains different flavor profiles, what Jamilly calls a “signature,” which contribute to the distinctive flavor of each meat. “That’s why pork tastes different from beef and ...
Vegetable oils and animal fats are the traditional materials that are saponified. These greasy materials, triesters called triglycerides , are usually mixtures derived from diverse fatty acids. In the traditional saponification, the triglyceride is treated with lye , which cleaves the ester bonds, releasing fatty acid salts (soaps) and glycerol .
Suet is the raw, hard fat of beef, lamb or mutton found around the loins and kidneys. Suet has a melting point of between 45 and 50 °C (113 and 122 °F) and congelation between 37 and 40 °C (99 and 104 °F).
The triglyceride derived from three molecules of stearic acid is called stearin. [9] Stearic acid is a prevalent fatty-acid in nature, found in many animal and vegetable fats, but is usually higher in animal fat than vegetable fat. It has a melting point of 69.4 °C (156.9 °F) °C and a pKa of 4.50. [11]
