Definition & Meaning of "margarine"

What is "margarine"?

Margarine is a spreadable, semi-solid substance typically made from vegetable oils or animal fats that have been processed to resemble butter. Originally created as a butter substitute, margarine often contains a blend of ingredients such as hydrogenated oils, water, emulsifiers, and sometimes milk solids or flavorings. It was initially developed as a cheaper alternative to butter and gained popularity during times when butter was scarce or expensive. Margarine is often used as a spread on bread, toast, or baked goods, and it can also be used in cooking and baking as a substitute for butter. However, it has faced scrutiny over the years due to concerns about its high trans fat content in some formulations, leading to the development of healthier margarine options that are lower in trans fats and higher in unsaturated fats.
