摘要

Supercritical carbon dioxide (scCO2) extraction offers environmental advantages over other techniques for extracting bioactive compounds from plant biomass. The effectiveness of scCO2 extraction can be enhanced by including a cosolvent in the process. When a vegetal oil is used as a cosolvent, further separation stages would be avoided, and a final product with improved functional and biological properties for food and nutraceutical products can be obtained. Coextraction or the joint extraction of bioactives from a primary solid matrix and an oil, acting as a cosolvent, from a secondary matrix, has been proposed as a solvent-free approach. This review presents an overview on the potential of coextraction as a strategy to valorize food and agricultural wastes and to develop novel products, containing both the solute and the cosolvent in a valuable, more stable, and bioavailable formulation of the bioactives.
