包套技术本来是有效地利用保护其所包容的物质 ,或者是通过包覆层 (膜或颗粒层 )以释放功能性物质的一种技术。所包覆的内容包括流动性固体、半固体、液体和气体等。近年来在包套技术方面以利用固态 液态之类物理化学状态变化而产生的吸热放热现象为目的的新技术开发受到很大 Envelope technology was originally a technique that effectively used to protect the material it contained, or to release the functional material through a coating (film or particle layer). The covered contents include liquid solids, semi-solids, liquids and gases. In recent years, the development of new technologies for the purpose of enrobing the endothermic exotherm resulting from changes in physicochemical states such as solid-state liquid in the enveloping technology has been greatly influenced
