# Understanding Microencapsulation

Microencapsulation is a process where tiny particles or droplets are surrounded by a coating to give small capsules, of many useful properties. In a relatively simple form, a microcapsule is a small sphere with a uniform wall around it. The material inside the microcapsule is referred to as the core, internal phase, or fill, whereas the wall is sometimes called a shell, coating, or membrane.

## Applications of Microencapsulation

Microencapsulation technology has been applied to a wide variety of applications:

1. **Pharmaceuticals**: Microencapsulation in the pharmaceutical industry is used to mask the taste of a drug, provide a barrier to environmental conditions, and control the release of a drug.

2. **Food and Beverages**: It is used in the food industry to extend shelf life, protect flavors, and encapsulate vitamins.

3. **Agriculture**: In agriculture, it is used to slowly release pesticides and fertilizers.

## Methods of Microencapsulation

There are several methods of microencapsulation, each with its advantages and disadvantages:

1. **Spray Drying**: This is the most common method of microencapsulation. It involves spraying the core material into a chamber with the shell material.

2. **Coacervation**: This method involves the separation of a solution into two liquid phases. The core material is dispersed in one phase, which is then encapsulated by the other phase.

3. **Polymerization**: This method involves forming a polymer shell around the core material.

## Advantages and Disadvantages

Microencapsulation has several advantages such as
