microencapsulation
microencapsulation Preparation of small particles of solids, or droplets of liquids, inside thin coatings (e.g. beeswax, starch, gelatine, and polyacrylic acid). The microcapsules range from 1 to 100 nm in size. Used to prepare liquids as free‐flowing powders or compressed solids, to separate reactive materials, reduce toxicity, protect against oxidation, and control the rate of release; used for enzymes, flavours, nutrients, etc.
