The size of the Brazilian agricultural and agro industrial market impress by its greatness but also by the amount of waste generated, being the cause of serious concerns about how to handle such residues. This kind of material comprises biomasses that carry potentially bioactive compounds that could add value to the process when extracted, integrating biomass-based chemical platforms (biorefineries). Notably, organic agricultural systems could be involved in the discussions, as they are not only considered greener production models but also because they are linked to a higher presence of flavonoids and other secondary metabolites that have bioactive properties. The central goal of this research project is to extract the main bioactive compounds from the processing waste of guava (Psidium guajava) and mango (Mangifera indica L.), from both conventional and organic agricultural systems produced in the state of São Paulo. Chemometrics tools will be used on experimental design to evaluate several green extraction methods, such as Microwave-Assisted Extraction (MAE), Matrix Solid Phase Dispersion (MSPD) and alternative solvent extraction (Ionic Liquids, ILs; and Deep Eutectic Solvents, DES). The extracts will be analyzed using liquid chromatography and the compounds will be quantified using commercially available standards (mangiferin, quercetin, coumarin, hyperoside, catechin and gallic acid). The methods will be studied to optimize the extraction yields and to evaluate their greenness using appropriate sustainable metrics. (AU)
