This article is a review about the ways in which solidification and the melting may occur within emulsions submitted to steady
cooling and heating performed in a differential scanning calorimeter. Simple, multiple and mixed emulsions are considered.
Due to nucleation phenomena creating supercooled and supersaturated liquids, the DSC curves obtained during cooling and heating
are quite different. The influence of a solute in the disperse phase is described in detail. Some implications about the instabilities
of emulsions due to mass transfer phenomena are described.
