Emulsion

What is an emulsion ?

An emulsion can be hot or cold and take on any flavor from sweet to savory; it can be smooth or have a bit of texture. No matter the type of emulsion, these dressings and sauces enhance the taste of the dish, bringing another level of flavor to foods such as salads and eggs. Emulsion is a dispersed system in which the phases include immiscible or partially miscible liquids, such as milk and rubber latex. If an emulsion is prepared by homogenizing two pure liquid components, phase separation will generally be rapid, especially if the concentration of the dispersed phase is at all high.

An Emulsion is a homogeneous mixture of several immiscible liquids with each other, such as oil and water in butter. The substances of an Emulsion remain linked to each other thanks to the action of an emulsifying substance that increases viscosity and stabilizes the emulsion. For example, soap or detergent are water and grease emulsifying substances. The substances of an Emulsion are separated by the emulsification process.

Types of emulsions

There are three types of emulsions, which are:

Flocculation

This type of emulsion is unstable, and the particles come together creating a mass.

Emulsion Paint

Cremation

The emulsion tends to concentrate on the surface of the mixture although it also accumulates separately at the bottom.

Coalescence

This type of emulsion acts by melting the particles into a liquid layer.

Usually the emulsions have a white color although if they are in a diluted form the light can be distorted, creating a blue or yellowish color.

Examples of Emulsions:

If you try to mix some cooking oil and water by whisking the mixture for a good while you will notice that the cooking oil divides into small oil droplets, which makes the mixture cloudy. A mixture containing small droplets of one liquid in another liquid is called emulsion . An emulsion is a type of heterogeneous mixture, since it is still possible to distinguish the various substances (in this case, the oil and water).

In order for an emulsion to occur, the substances contained in it must be insoluble in each other. Thus, ethanol and water which are infinitely soluble in each other cannot form an emulsion.

Oil in the water emulsion in our example will not remain an emulsion for very long. After only a few seconds, the oil droplets clump together to form a layer over the water. Then we no longer have a mixture but two separate substances. In order for an emulsion to remain an emulsion, emulsifiers are often used , a concept that you have probably seen on different food packaging. The emulsifiers are used to give the right consistency to the food they are used in. In egg yolks, for example, there is a natural emulsifier called lecithin which is useful when making mayonnaise which is an oil in water emulsion.

An emulsifier which hopefully does not appear in food, but which is nonetheless functional, is detergent. If you add a few drops to the mixture of cooking oil and water and stir, you will notice that it continues to be an emulsion for much longer.

In addition to mayonnaise, margarine and milk are two emulsions. Many skin care products are also examples of emulsions. Here is a list of examples of emulsions :

Water and grease emulsion in washing with soap or detergent
In milk there is an emulsion of water and fatty substances
Mayonnaise (water and oil emulsion)
Margarine
Vinaigrette (pickled oil emulsion)
Ice cream
Espresso coffee cream (oil in water)
Yogurt
Dressings
Hollandaise sauce
Vaccinations
Cosmetic lotions
Skin moisturizing substances
Balms
Photographic emulsions
Petroleum
Asphalt (bitumen)
Pesticides
Paintings

emulsion

[e-mul´shun]

a mixture of two immiscible liquids, one being dispersed throughout the other in small droplets; a colloid system in which both the dispersed phase and the dispersion medium are liquids. Margarine, cold cream, and various medicated ointments are emulsions. In some emulsions the suspended particles tend to join together and settle out; hence the container must be shaken each time the emulsion is used.

Emulsion

film emulsion a dehydrated gel emulsion of light- or radiation-sensitive silver halide that is applied to a suitable base.

(ē-mŭl'shŭn),

A system containing two immiscible liquids in which one is dispersed, in the form of small globules (internal phase), throughout the other (external phase) (for example, oil in water [milk] or water in oil [mayonnaise]).
