Margarine is a versatile food spread used for flavoring, baking, and cooking. It often serves as a substitute for butter.

Scientifically, margarine is a water-in-fat emulsion. This means tiny droplets of water are dispersed uniformly throughout a fat phase to create a stable solid. While butter is made by concentrating milk butterfat through centrifugation, modern margarine requires intensive processing. Most margarine consumed today is produced from refined vegetable oils rather than animal fats. It is a common ingredient in many baked goods, including pastries, doughnuts, cakes, and cookies.

The manufacturing process begins with the extraction and refinement of oils and fats. These oils may undergo hydrogenation to become solid.

Hydrogenation involves passing hydrogen gas through the oil using a nickel catalyst. This process converts unsaturated bonds into saturated bonds, which raises the melting point and "hardens" the oil. To create the emulsion, a water or milk mixture is prepared separately from the oil. This mixture contains water-soluble additives like salt, skimmed milk, citric acid, or lactic acid. Emulsifiers such as lecithin are added to help the oil and water stay mixed.

During mixing, the fats are warmed to a liquid state. The oil is then slowly added to the water mixture with constant stirring. Finally, the mixture is rapidly chilled to prevent large crystals from forming, ensuring a smooth texture. The product is then rolled, kneaded, or aerated with nitrogen to improve spreadability.

Margarine products are categorized into several distinct types based on their texture and use. Bottled liquid margarine is used for cooking or topping dishes. Soft vegetable fat spreads are high in mono- or polyunsaturated fats. These are often made from oils like safflower, sunflower, soybean, cottonseed, rapeseed, or olive oil. Hard margarine is typically used for more intensive cooking or baking tasks. The fat content in these products can range widely from 10% to 90%. This variation allows manufacturers to target different dietary needs and culinary purposes.

The history of margarine is rooted in 19th-century chemistry. In 1813, French chemist Michel Eugène Chevreul discovered margaric acid. Later, in 1869, Hippolyte Mège-Mouriès invented margarine to meet a challenge from Napoleon III. The Emperor wanted a butter substitute made from beef tallow for the military and lower classes.

Mège-Mouriès patented his invention as "oleomargarine." This name combined the Latin word "oleum" for oil and the Greek word "margarite" for pearl. In 1871, the patent was sold to the Dutch company Jurgens. That same year, Benedict Klein opened the first margarine factory in Germany.

As the industry grew, it faced significant political and social challenges. In the late 19th century, the American butter industry lobbied against margarine manufacturers. This resulted in the 1886 Margarine Act, which imposed heavy taxes and fees.

There was also a famous debate regarding the color of the spread. Because margarine was naturally white, manufacturers began adding yellow coloring in the late 1880s to mimic butter. This led to laws in some places, like Wisconsin, that prohibited coloring until 1967. For a time, companies had to include a separate packet of yellow dye for consumers to mix in manually.

In 1951, a new patent allowed for a yellow dye capsule to be placed inside the plastic packaging.

During the 1930s and 1940s, unique industrial methods emerged. In Germany, Arthur Imhausen developed a process to produce edible fats from synthetic paraffin wax made from coal. This "coal butter" was nutritious and provided up to 700 calories per day. However, the process was inefficient, requiring 60 kilograms of coal to produce just one kilogram of synthetic butter. This method was eventually discontinued after World War II. During the war, rationing in the United States and United Kingdom also changed how margarine was produced and consumed.

In the modern era, the terminology and composition of spreads continue to evolve. In the mid-1960s, new products in Scandinavia led to the term "spread" to describe blends with lower fat content. In the United States, products with less than 80% fat can be labeled as spreads rather than margarine. This distinction helps manufacturers avoid the less popular "margarine" label. Today, many brands focus on health-conscious features. These include trans fat-free recipes, added omega-3 fatty acids, or plant sterols. Some even offer novelty items, such as pink margarine in plastic squeeze bottles.
