O`le*o*mar"ga*rine, n. Etym: [L. oleum oil + E. margarine, margarin.]
[Written also oleomargarin.]
1. A liquid oil made from animal fats (esp. beef fat) by separating
the greater portion of the solid fat or stearin, by crystallization.
It is mainly a mixture of olein and palmitin with some little
stearin.
2. An artificial butter made by churning this oil with more or less
milk.
Note: Oleomargarine was wrongly so named, as it contains no margarin
proper, but olein, palmitin, and stearin, a mixture of palmitin and
stearin having formerly been called margarin by mistake.
