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.
Animal glue in granules. Animal glue is an adhesive that is created by prolonged boiling of animal connective tissue in a process called rendering. [1] In addition to being used as an adhesive, it is used for coating and sizing, in decorative composition ornaments, and as a clarifying agent.
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.
Bear's grease was made from the fat of the brown bear mixed with beef marrow and a perfume to disguise the smell. Before the start of the twentieth century, manufacturers were substituting pig, [4] veal, suet, lard and beef marrow fat for bear's fat as the demand exceeded the available supply of genuine bear's fat.
In dry rendering, the fat is exposed to high heat in a pan or oven without water (a process similar to frying bacon). The two processes yield somewhat differing products. Wet-rendered lard has a more neutral flavor, a lighter color, and a high smoke point. Dry-rendered lard is somewhat browner and has a caramelized flavor and has a lower smoke ...
The English name reflects the historical use of the material for fulling (cleaning and shrinking) wool, by textile workers known as fullers. [1] [2] [3] In past centuries, fullers kneaded fuller's earth and water into woollen cloth to absorb lanolin, oils, and other greasy impurities as part of the cloth finishing process.
"Grease" or "yolk'' is a combined form of dried sweat, oil and fatty matter. [29] Lanolin is the major component (5-25%) of raw wool which is a waxy substance secreted by the sebaceous glands of wool-bearing animals. [30] Greasy matter varies by breed. [31] Following the cleaning process, the wool fibers possess a chemical composition of ...
The industry which collects and renders yellow grease to make refined used cooking oil is dominated by a number of very large companies. [6] No reliable statistics exist on the number of smaller to mid-size companies who collect yellow grease and either sell or render it to produce refined used cooking oil. Estimates run to a couple of hundred.
