Margarine

Margarine (/ˈmɑːrdʒəriːn/, also UK: /ˈmɑːrɡə-, ˌmɑːrɡəˈriːn, ˌmɑːrdʒə-/, US: /ˈmɑːrdʒərɪn/ ^ⓘ) is a spread used for flavoring, baking, and cooking. It is most often used as a substitute for butter. Although originally made from animal fats, most margarine consumed today is made from vegetable oil. The spread was originally named oleomargarine from Latin for oleum (olive oil) and Greek margarite ("pearl", indicating luster). The name was later shortened to margarine, or sometimes oleo (particularly in the Deep South region of the United States).

Margarine consists of a water-in-fat emulsion, with tiny droplets of water dispersed uniformly throughout a fat phase in a stable solid form. While butter is made by concentrating the butterfat of milk through centrifugation, modern margarine is made through a more intensive processing of refined vegetable oil and water.

Margarine can be used as an ingredient in other food products, such as pastries, doughnuts, cakes, and cookies.
