For each of the technologies listed below, give its main feature or mode of action that allows it to fulfill its purpose: Microencapsulation.

Microencapsulation is a process where tiny particles or droplets are surrounded by a coating to give small capsules with many useful properties. The main feature of microencapsulation that allows it to fulfill its purpose is the ability to control the release of the encapsulated material. This can be achieved by selecting appropriate encapsulation materials and techniques. The encapsulation can protect the core material, isolate it from the surroundings, and control its release over time. This technology is widely used in various fields such as pharmaceuticals, food and beverage, agriculture, and cosmetics.
