Editing Transesterification (section)

===Fat processing===
[[Fat interesterification]] is used in the [[food industry]] to rearrange the [[fatty acid]]s of [[triglyceride]]s in edible [[fat]]s and [[vegetable oil]]s. For example, a solid fat with mostly saturated fatty acids may be transesterified with a vegetable oil having high unsaturated acid contents, to produce a spreadable semisolid fat whose molecules have a mix both kinds of acids.
