Abstract
The present invention is related to the production of capsules or particles of micro and nanometric size, for introduction into food, using stable electrified coaxial jets of two immiscible liquids with diameters in the micro and nanometric range. An aerosol of charged structured droplets forms when the jets dissociate by capillary instabilities. The structured droplets, which are mano-dispersed in size, contain a first liquid (generally the material desired to be added) that is surrounded by a second liquid. Generally the second liquid provides a barrier or protective coating which allows the addition of the first liquid to a food product without adversely affecting the organoleptic or other properties of the food product.
