Emulsifiers are substances that are added to liquid components to stabilize the mixture. For example, when oil and water are combined, they will eventually split into two layers when left to their own devices. An emulsifier has stabilizing properties that distribute the oil and water molecules evenly throughout the mixture to avoid separation. Emulsifying is used to make foods visually appealing and enhances flavor and texture.

Monoglycerides are a combination of glycerin and fatty acids. According to UnderstandingFoodAdditives.org, monoglycerides are one of the most common types of emulsifiers. Lecithin, a monoglyceride commonly found in egg yolk, is often used as an emulsifier. Animal fats and vegetable oils can be used for the manufacture of artificial emulsifiers. Emulsifiers also come in different forces depending on the size of their molecular structures. A high molecular size emulsifier, such as the diacetyltartaric acid esters of monoglycerides used in bread, is more effective than those with smaller molecular structures.

Due to their unique molecular structure, emulsifiers can prevent the separation of oil and water. One end of the molecule is hydrophilic or water-attracted. The other end of the molecule is lipophilic or oil-attracted. As each end of the molecule is attracted to one of the two main substances in the mixture, the emulsifiers are evenly distributed throughout the water and oil and do not form a separate third layer. Emulsifiers keep the oil and water evenly distributed so that they do not form separate layers.

Some foods are often used as emulsifiers. According to the Food Network, milk, eggs, mustard and gelatin can be added to oil and water mixtures for emulsification. The mixtures can be emulsified by hand by adding an emulsifier to a water-based mixture, then slowly pouring into oil with vigorous stirring. Continuous stirring ensures that the emulsifier is evenly distributed throughout the mixture to prevent separation of oil and water. Oil-based salad dressings (such as Caesar dressing) and mayonnaise often require this technique.

Emulsifiers are one of the most common additives in processed foods. The dispersion of low fat margarine depends to a large extent on the addition of emulsifiers. If the oil separated into the spread, it would be prone to mold. Emulsifiers are also used to enhance the texture of processed baked products. If the oil is not evenly distributed in dough or dough, the product is denser than flakes or light. The processed food industry also uses emulsifiers to prevent objects from becoming thin or damp over time, such as sauces or sauces.

After understanding the food additives. org, emulsifiers are used in a variety of foods. Although baked goods, mayonnaise and margarine rely more on emulsifiers, they are also used to extend the shelf life of breakfast cereals and dehydrated potato flakes. Emulsifiers are added to soft drinks to avoid separation of sugars and other materials. They also help caramel, caramel and chewing gum while retaining their textures.
