Microencapsulation is a process in which tiny particles or droplets are surrounded by a coating to give small capsules, with useful properties. In general, it is used to incorporate food ingredients, enzymes, cells or other materials on a micrometric scale. Microencapsulation can also be used to enclose solids, liquids, or gases inside a micrometric wall made of hard or soft soluble film, in order to reduce dosing frequency and prevent the degradation of pharmaceuticals.

微囊化（英語：Micro-encapsulation）是指利用天然的或合成的高分子材料（统称为「囊材」）作为囊膜壁壳，将固态或液态物质包裹成为的直径在一到一微米的胶囊。其内容物称之为芯材。由于芯材被囊材包裹 ，所以其化学性质几乎不受影响。并且，由于囊材几乎都有半透膜的特性，故芯材可借压力、pH值、、温度或提取等方法完全释放出来。
