MARGARINE , the name, first given by See also:

Chevreul, to an artificial substitute for See also:butter, made from See also:beef and other animalfats, and sometimes mixed with real butter. The name of " butterine " has also been used. Artificial butter, or " margarine-mouries," was for some years manufactured in See also:Paris according to a method made public by the eminent chemist Mege-Mouries. Having surmised that the formation of butter contained in See also:milk was due to the absorption of See also:fat contained in the See also:animal tissues, he was led to experiment on the splitting up of animal fat. The See also:process he ultimately adopted consisted in See also:heating finely minced beef See also:suet with See also:water, carbonate of potash, and fresh See also:sheep's See also:stomach cut up into small fragments. The mixture he raised to a temperature of 450 C. (113° F.). The See also:influence of the pepsine of the sheep's stomach with the See also:heat separated the fat from the cellular See also:tissue; he removed the fatty See also:matter, and submitted it when cool to powerful See also:hydraulic pressure, separating it into stearin and oleomargarin, which last alone he used for butter-making. Of this fat about the proportions of ro lb with 4 pints of milk, and 3 pints of water were placed in a See also:churn, to which a small quantity of See also:anatto was added for colouring, and the whole churned together. The See also:compound so obtained when well washed was in See also:general See also:appearance, See also:taste and consistency like See also:ordinary butter, and when well freed from water it was found to keep a longer See also:time. Margarine is a perfectly wholesome butter-substitute, and is now largely used, but the ease with which it may be passed off as real butter has led to much discussion and legislative See also:action.
