Lipid based carriers have been widely used for encapsulation
and delivery of hydrophobic compounds in food, pharmaceutical
and cosmetic industries . Among the
various approaches used to classify these carriers, one approach is
based on the physical state of the lipid phase. Based on this
approach, lipid carriers that are commonly used in diverse
applications can be classified as solid lipid nanoparticles (SLNs)
with a solid lipid phase, emulsions with a
fluid lipid phase and
nanostructured lipid carriers with a combination of solid and
liquid lipids,
