Application of Supercritical Fluids in the Conservation of Bioactive Compounds: A Review

The precipitation from supercritical antisolvents (SASs) of natural compounds solutions has become an excellent alternative to improve the solubility and availability of poorly water-soluble compounds. In this technique, CO₂ is used as a supercritical fluid that marks the processing as a green technology and is ideal for use in the food industry due to its nontoxicity, economy and easy separation of solutes. This article reviews the application of the SAS technique in the food industry and highlights the influential factors in the generation of micro- and nanoparticles
