Emulsions
result from mixing two mutually insoluble liquids. They are disperse
systems consisting of an internal or dispersed phase containing
oil, and an external or continuous phase based on water. The result
is an oil-in-water emulsion. To obtain stabilization, an emulsifier
should be used; its function is to rapidly decrease the interfacial
tension to restore stability in highly unstable emulsion systems.
The use of soluble polymers, such as XANTHAN GUM
helps to stabilize the emulsion. By increasing the viscosity of
the external phase, it slows down the motion of the droplets contained
in the emulsion and prevents fat matters from rising.
