margarine

margarine, manufactured substitute for butter. It consists of a blend of vegetable oils or meat fats (or a combination of both) mixed with milk and salt. It was developed in the late 1860s by the French chemist Hippolyte Mège-Mouries in a contest sponsored by Napoleon III for a butter substitute. Beef fat, known as oleo oil, was chiefly used at first, but later was supplemented by pork and other animal fats and by vegetable oils such as coconut oil, olive oil, and cottonseed oil. At present, most margarines contain only vegetable oils; the margarine produced in the United States is usually made from corn, cottonseed, or soybean oil. The oils, refined, deodorized, and hydrogenated to the desired consistency, are churned or homogenized, usually with cultured skim milk, then chilled and reworked to incorporate salt and remove excess water. Margarine is similar in composition to butter, yields practically the same number of calories, and is easily digestible. It is commonly fortified with vitamin A and vitamin D. In the 1960s a new type of margarine was developed made of polyunsaturated fats (see cholesterol). Margarine is sometimes called oleomargarine.

margarine

Food made from one or more vegetable or animal fats or oils mixed with milk and other ingredients. It is used in cooking and as a spread as a substitute for butter. Margarine was developed by the French chemist Hippolyte Mège-Mouriès in the late 1860s. The fats used have varied widely; polyunsaturated oils such as corn, canola, and sunflower oil, considered more healthful than saturated fats, are common today.
