Rendering is a process that converts waste animal tissue into stable, usable materials. Rendering can refer to any processing of animal products into more useful materials, or, more narrowly, to the rendering of whole animal fatty tissue into purified fats like lard or tallow. Rendering can be carried out on an industrial, farm, or kitchen scale.
Tallow made by rendering calf suet. Tallow is a rendered form of beef or mutton suet, primarily made up of triglycerides. In industry, tallow is not strictly defined as beef or mutton suet. In this context, tallow is animal fat that conforms to certain technical criteria, including its melting point.
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 . [ 2 ] [ 3 ] Although many animal parts and secretions may yield oil, in commercial practice, oil is extracted primarily from rendered tissue fats from livestock animals like pigs ...
Nutrition experts explain the nutrition of beef tallow after RFK Jr. says that beef tallow is healthier than seed oil. Kennedy called seed oils “one of the driving causes of the obesity epidemic.”
Tallow after rendering. The primary use of suet is to make tallow, although it is also used as an ingredient in cooking, especially in traditional baked puddings, such as British Christmas pudding. Suet is made into tallow in a process called rendering, which involves melting fats and extended simmering, followed by straining, then cooling. The ...
The Texas-based company has agreed to close a tallow plant in Fresno next year due to long-term complaints about noxious odors and wants to move some of that work to its rendering facility on ...

In wet rendering, pig fat is boiled in water or steamed at a high temperature and the lard, which is insoluble in water, is skimmed from the surface of the mixture or separated in an industrial centrifuge. In dry rendering, the fat is exposed to high heat in a pan or oven without water (a process similar to frying bacon).
