Beef tallow, melting property

Studies have been pubhshed on chemical interesterification of tallow with regular sunflower oil (96-98). Changes in the proportion of sunflower oil in blends with tallow produce httle modification of the solid content or the melting point. However, important modifications take place in the thermal properties of these blends when they are subjected to a process of chemical interesterification. In addition, modifications occur in the crystalline structure. Solid beef tallow—composed... 

Beef tallow is the main t. used. There are other types, such as mutton t. (- tallow (mutton), which is used only industrially and has similar properties as beef tallow. Neatsfoot oil is a low-melting fat rendered from the feet of cattle it is used as - lubricant and in fat liquors (- leather auxiliaries). There are many grades and types of t., depending on the part of the animal from which it originates, the season of slaughtering, the ffa content, color, odor and many other factors.
