Concerning the applications in food technology, two recent
reviews about possibilities of nanotechnology [19•
,20] indicate
that there are potential applications of nano-emulsions, but no
specific applications are given. In Ref. [19•
], potential applications
for nanostructured materials in general are analyzed,
but regarding nano-emulsions, only a mention about their
potential application is made. In Ref. [20], a detailed review on
emulsification techniques is presented but the possible applications
that are indicated are not likely to have an important impact
in the future food technology. Finally, nano-emulsification of
carotene containing hexane is described in Ref. [21] although the
final application proposed after evaporation of hexane is a
dispersion of carotene, not a nano-emulsion.
