Encapsulation techniques are used to preserve and protect ingredients in foods. Microencapsulation coats droplets of liquids, solids or gases in thin films that control release under different conditions. This allows controlled release of flavors and protects ingredients. Encapsulation finds applications in foods like dry beverage mixes and chewing gum where it prolongs flavor sensation and shelf life. There is also increased demand for encapsulation of vitamins and nutraceutical ingredients to mask strong flavors. Nanocapsules provide targeted delivery systems to carry and release flavors or nutrients when desired. Fabricated and instant foods incorporate encapsulated ingredients to add nutrition and convenience.
