Some food emulsifiers are egg yolk, Monoglyceride & Diglyceride, Mucilage (in mustard) and many some others.

General Concept of Emulsifiers (All you need to know)


Emulsifier

This is a chemical/substance/compound that assists in stabilizing an Emulsion. Emulsion is the suspension or dispersion of a liquid in another liquid that are not normally soluble (Immiscible) and forms an heterogeneous mixture.

Why doesn't Oil and water Mix?
Oil has molecules that are as Non-polar and therefore can not mix or be soluble in Water which has polar molecules.

Figure one, Oil floating on water as a result of difference in a variable density.

Oil/Water don't mix

Only Polar molecules can dissolve and attract other polar molecules. This is as a result of the said molecules having charges on both ends. That is, one end of the each molecule has a positive charge and the other end has a Negative charge.

Oil molecules are non polar molecules and therefore can not mix with polar molecules. This is because Non-polar attracts non polar.

Hydrophilic and lipophilic
For Figure two below,  Working principle of Emulsifier.

Hydrophilic and lipophilic

The Emulsifier generally composes of a Water loving Hydrophilic head region and the Oil-Loving Lipophilic tail. Emulsifiers has several uses, functions and application with its distinct feature in helping to stabilize texture and increase shelf life of Food and Cosmetics.
