The average diameter of droplets in Micro-emulsion varies from 1 to 100 nm, while that of ordinary emulsions is approximately from 1 to 2 μm. Micro-emulsion enables the encapsulation of oil soluble compounds (including volatile components) which is thermodynamically stable and gives excellent clarity.Dispersion made of oil soluble flavor, the micro-emulsion flavoring is of excellent long-term stability, superior in water-solubility, fragrance and taste. Low water content or even NO water reduces risk of microorganism. No ethanol used makes Halal certified possible.

Microencapsulation is a process in which tiny particles or droplets are surrounded by a coating to give small capsules. It is used to increase the stability and life of the aroma compounds being encapsulated.
