Cyclodextrin-assisted extraction of phenolic compounds: Current research and future prospects

The addition of CD to the water improves the extraction efficiency for PC and shortens the extraction time, and the obtained PC extract present better antioxidant activity. Not only is the removal of CD unnecessary, but also the presence of CD favors the preparation of the PC extract in a solid state, which are very beneficial since they will be expected to be used either to fortify foods or as a food supplement on an industrial scale. However, further studies are required to evaluate the possibility of combining CDs with other extraction methods, such as high hydrostatic pressure, pulsed electric fields, negative pressure cavitation and pressurized liquid extraction, to extract PC from natural materials.
