Abstract(s)
For a long time, the importance of sample preparation and extraction in the analytical
performance of the most diverse methodologies have been neglected. Cumbersome
techniques, involving high sample and solvent volumes have been gradually miniaturized
from solid-phase and liquid-liquid extractions formats and microextractions approaches
are becoming the standard in different fields of research. In this context, this review is
devoted to the analysis of bioactive compounds in foods using different microextraction
approaches reported in the literature since 2015. But microextraction also represents
an opportunity to mitigate the environmental impact of organic solvents usage, as well
as lab equipment. For this reason, in the recent literature, phenolics and alkaloids
extraction from fruits, medicinal herbs, juices, and coffee using different miniaturized
formats of solid-phase extraction and liquid-liquid microextraction are the most popular
applications. However, more ambitious analytical limits are continuously being reported
and emergent sorbents based on carbon nanotubes and magnetic nanoparticles will
certainly contribute to this trend. Additionally, ionic liquids and deep eutectic solvents
constitute already the most recent forefront of innovation, substituting organic solvents
and further improving the current microextraction approaches.
