Animal fats are lipids derived from animals which are used by the animal for a multitude of functions, or can be used by humans for dietary, sanitary, and cosmetic purposes. Depending on the temperature of the fat, it can change between a solid state and a liquid state. Chemically, both fats and oils are composed of triglycerides.
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.

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 .
Margarine has its roots in the discovery by French chemist Michel Eugène Chevreul in 1813 of margaric acid. [10] Scientists at the time regarded margaric acid, like oleic acid and stearic acid, as one of the three fatty acids that, in combination, form most animal fats.
Pentadecylic acid, also known as pentadecanoic acid or C15:0, is an odd-chain saturated fatty acid.Its molecular formula is CH 3 (CH 2) 13 CO 2 H.It is a colorless solid. A laboratory preparation involves permanganate oxidation of 1-hexadecene (CH 3 (CH 2) 13 CH=CH 2).
