In recent years, there has been a growing interest in the nanoencapsulation of wide variety bioactive compounds by extracting emulsions using Supercritical Fluid Extraction Emulsions (SFEE) process for development nutraceutical products and functional foods. This work includes information both fundamentals stages SFEE process. It also describes different equipment configurations used, such as spray, bubble column, or countercurrent columns operating batch process, semi-continuous, and/or continuous mode. addition, this focuses on explaining effect operational variables (emulsion composition, scCO2 pressure, temperature, emulsion flow rates, time) main physicochemical properties polymeric nanocapsules. Therefore, provides fundamental perspectives to contribute progress design compound-loaded nanocapsules with advantages higher encapsulation efficiency, low organic residual solvents, smaller size, well adapting large-scale productions healthier more bioavailable food products.
