there may also be a reduction
in the amount of light reaching the carotenoids in the
oil droplets. Another advantage of multilayer emulsions is that
the layers can be engineered to release from the droplet under
certain environmental conditions. Therefore, these delivery systems
could be created in such a way that they could allow for
triggered release of carotenoids during digestion (McClements
et al., 2007). This might possibly reduce the degradation of
carotenoids during the digestive processes prior to absorption,
and may improve bioavailability.
