Although alginate encapsulation or entrapment of oil soluble flavors is quite different from traditional encapsulation methods, it could serve as a valuable tool for liquid systems where a protective effect, delayed release, or combination texture/flavor effect is needed. 

Figure 5. Release from alginate-encapsulated liposomes. In vitro experiments were performed as follows Encapsulated liposomes were suspended in 10 ml of physiological saline in a screw-capped vial. In cylindrical polypropylene mesh cages (mesh size 105u the mesh was obtained from Fisher Scientific, cut into 2x2.5 inch rectangles, sewn up the side with nylon thread, and sealed at the bottom with a wax plug). Release was at 37°C on a rotary shaker. The encapsulated liposomes were frequently transferred to vials containing fresh buffer in order to mimic the infinite sink conditions of the body.
