A process for obtaining a microscopic physical state of xanthophylls or
oxycarotenoids derivatives forms such as diacetates or dipropionates
derivatives, which are readily incorporated in the digestive system as
micelles providing an improved bioavailability, as compared to the
bioavailability of carotenoids that are ingested in diverse preparations
that contain microscopic carotenoids crystals and a method for its
application.
