What is emulsion
  • 1 answers

Yogita Ingle 6 years, 9 months ago

An emulsion is a colloid of two or more immiscible liquids where one liquid contains a dispersion of the other liquids. In other words, an emulsion is a special type of mixture made by combining two liquids that normally don't mix. The word emulsion comes from the Latin word meaning "to milk" (milk is one example of an emulsion of fat and water). The process of turning a liquid mixture into an emulsion is called emulsification.

Examples of Emulsions:
(i) Oil and water mixtures are emulsions when shaken together. The oil will form drops and disperse throughout the water.
(ii) Egg yolk is an emulsion containing the emulsifying agent lecithin.
(iii) Crema on espresso is an emulsion consisting of water and coffee oil.
(iv)  Butter is an emulsion of water in fat.
