By definition, vinaigrette is an emulsion of an acid within a fat. To create the emulsion, mustard is a great ingredient to use. It's key to keeping the vinaigrette from separating.
How To Make Your Own Vinaigrette. The ingredients: oil (see my top picks below) acid (vinegar or citrus juice) a sweetener. a thickener. a dash of salt and pepper.
Making vinaigrette – pouring oil into vinegar and mustard prior to whipping into emulsion. In general, vinaigrette consists of 3 parts of oil to 1 part of vinegar whisked into an emulsion. Salt and pepper are often added. Herbs and shallots, too, are often added, especially when it is used for cooked vegetables or grains.
In Western culture, there are two basic types of salad dressing: Vinaigrettes based on a mixture of olive or salad oil and vinegar and variously flavored with herbs, spices, salt, pepper, sugar, and other ingredients such as poppy seeds or ground Parmesan cheese [1]
Homogenized milk – an emulsion of milk fat in water, with milk proteins as the emulsifier; Vinaigrette – an emulsion of vegetable oil in vinegar, if this is prepared using only oil and vinegar (i.e., without an emulsifier), an unstable emulsion results; Water-in-oil emulsions are less common in food, but still exist:
Creaming, in the laboratory sense, is the migration of the dispersed phase of an emulsion under the influence of buoyancy.The particles float upwards or sink depending on how large they are and density compared to the continuous phase as well as how viscous or how thixotropic the continuous phase might be.
In polymer chemistry, emulsion polymerization is a type of radical polymerization that usually starts with an emulsion incorporating water, monomers, and surfactants.The most common type of emulsion polymerization is an oil-in-water emulsion, in which droplets of monomer (the oil) are emulsified (with surfactants) in a continuous phase of water.
Low-energy methods - For the low-energy methods, the water-in-oil emulsion is usually prepared and then transformed into an oil-in-water miniemulsion by changing either composition or temperature. The water-in-oil emulsion is diluted dropwise with water to an inversion point or gradually cooled to a phase inversion temperature.
