摘要：
An encapsulation process including: (a) forming an emulsion composed of a continuous phase comprising a first liquid, a cationic material, and an anionic material, and a disperse phase composed of a plurality of droplets of a second liquid, wherein a number of the droplets includes therein one to five particles; and (b) inducing complex coacervation of the cationic material and the anionic material to form a shell around each of the droplets. Preferably the shell is gelled and subsequently hardened.
