Flavors play an important role in the food， textiles， spices， cosmetics， agriculture and pharmaceutical industries. They are also one of the key factors that determine the quality of products. However， many flavors have the poor stability， and are vulnerable to some negative impact， such as light， heat， oxygen and mechanism. And the physicochemical property and solution characteristics of flavors limit their application. In addition， controlling the release of flavors is also a major aspect. Therefore， delivery systems can be used for proper protection， delivery and release of flavors. The present article comprehensively introduces the research progress of flavors delivery systems， briefly introduces the properties and functions of important food components （protein， polysaccharides， lipids and so on） in flavors delivery systems. The main types， structures and characteristics of flavors delivery systems were introduced， and the application prospect is predicted.
