Meaning and Definition
A process of enclosing tiny particles or droplets within a microscopic capsule or coating.
A technology used to protect sensitive materials (e.g., vitamins, fragrances, drugs) from environmental factors, control their release, or mask their taste/smell by surrounding them with a thin, solid shell. It can also refer to the fundamental concept of isolating a small core material within a protective barrier at the micro-scale.

Frequently Asked Questions
No, it is a highly specialised technical term used primarily in scientific research, industrial manufacturing (pharma, food, cosmetics), and advanced engineering fields. The average native speaker would not know or use it.
The primary purposes are: 1) Protection of a sensitive core material (e.g., a vitamin) from oxygen, light, or moisture. 2) Controlled or timed release of the core material. 3) Masking an undesirable taste, colour, or odour. 4) Converting a liquid into a handleable solid powder.
Yes, the corresponding verb is 'to microencapsulate'. It follows the regular conjugation pattern (microencapsulates, microencapsulating, microencapsulated).
