Detailed explanation-1: -An emulsion is a type of colloid formed by combining two liquids that normally don’t mix. In an emulsion, one liquid contains a dispersion of the other liquid. Common examples of emulsions include egg yolk, butter, and mayonnaise. The process of mixing liquids to form an emulsion is called emulsification.
Detailed explanation-2: -Emulsification is the process of dispersing two or more immiscible liquids together to form a semistable mixture. In food applications, these two liquids generally consist of an organic (oil) phase and an aqueous (water) phase that is stabilized by the addition of a food-grade emulsifier (surfactant).
Detailed explanation-3: -Mayonnaise is an example of an oil-in-vinegar emulsion. Mayonnaise, like all emulsions, contains an emulsifier…in this case, the incredible, edible egg. Egg yolk contains the phospholipid lecithin. Each lecithin molecule contains a polar end that is attracted to water and a non-polar end that is attracted to oil.
