Microcapsules containing fish oil with proteins as well were prepared using oil-in-water-in oil (O/W/0) double emulsification followed by gelation method (heat or enzyme) (Cho et al., 2003). The oil phase may be the base to include oil-soluble ingredients. 

Fabrication Various multiple-unit floating systems have been developed in different forms and are based on various principles, such as air compartment multiple-unit system, microparticles based on porous carriers, hollow microspheres (microballoons), and oil-entrapped gel beads prepared by gelation method...
