In this work, reverse micelle-based supramolecular solvent microextraction method coupled with supercritical fluid extraction and used for determining trace amounts of polycyclic aromatic hydrocarbons in apple peels. The extract was analyzed by high-performance liquid chromatography equipped with a fluorescence detector. Coupling supramolecular solvent microextraction with supercritical fluid extraction method, resolve low preconcentration factor of supercritical fluid extraction method, improved limit of detection of polycyclic aromatic hydrocarbons and allow the use of supramolecular solvent microextraction in solid matrices. The effective parameters on the supramolecular solvent microextraction and supercritical fluid extraction efficiency were optimized using one variable at a time and face centered design methods, respectively. Under the optimum condition, the limits of detection and limits of quantifications were in the range of 0.34-1.27 and 1.03-3.82 µg/kg, respectively. Analysis of polycyclic aromatic hydrocarbons in apple peels showed that the supercritical fluid extraction/ supramolecular solvent microextraction method provide great potential for trace analysis of polycyclic aromatic hydrocarbons in fruit samples (RSDs < 7.7%).

Coffee pulp (CP) is the by-product of coffee processing that urgently needs to be revalorized using sustainable technologies. This work applied a design of experiment (DoE) for modeling the extraction of bioactive compounds from CP using supercritical carbon dioxide (sc-CO) with ethanol as a co-solvent under variable conditions (temperature, pressure, and ethanol percentage). Considering extraction efficiency (per unit of CP) and extraction selectivity (per unit of extract), results showed that ethanol percentage significantly enhanced the efficiency of total phenolic content, as well as the selectivity of chlorogenic acid and protocatechuic acid (p < 0.

This study aimed to promote the valorization of lupin seeds by extracting both non-polar and polar fractions to produce a protein-rich flour suitable for food applications. Green extraction methods such as Supercritical Fluid Extraction (SFE) and SFE followed by gas-expanded liquid extraction with ethanol/CO mixtures were employed. SFE yielded lupin oil with extraction yields ranging from 2.
