Green extraction techniques for obtaining bioactive compounds from mandarin and pomegranate peel: Phytochemical analysis and process optimization

Abstract

This study used advanced green extraction techniques to examine the effective utilization and valorization of
mandarin and pomegranate peels. Several extraction techniques have been collected in the literature for the
extraction of bioactive components from mandarin and pomegranate peel in the first step of this investigation.
Due to high applied temperatures and pressures or lengthy extraction times (the conventional solvent extraction),
extraction procedures can degrade phenolic compounds. The polarity of phenolic compounds, however, sets
limits on different recovery methods, including supercritical CO2 separation. To speed up the extraction process,
enhance extraction yield, and prevent phenolic compounds from degrading, new methods of extracting bioactive
compounds have been developed. The various extraction techniques used to extract the phenolic components from
mandarin and pomegranate peels are critically compared in this article. The review combines essential information
that may be helpful in selecting the best extraction technique for bioactive chemicals from natural sources.
