Green Extraction Strategy Using Bio-Based Aqueous Biphasic Systems for Polyphen...
Dimitrijević, Aleksandra; Marić, Slađana; Jocić, Ana; Tekić, Danijela; Mušović, Jasmina; Amaral, Joana S.Polyphenols are natural compounds with enhanced antioxidant properties. They are present in relatively high concentrations in fruit/vegetable by-products. Therefore, there is a need for the development of efficient and cost-effective methods for the separation and purification of these valuable compounds. Traditional extraction with organic solvents needs to be switched to novel methods that are more efficient,...
Aqueous biphasic systems comprising copolymers and cholinium-based salts or ion...
Dimitrijević, Aleksandra; Paula M. Tavares, Ana; Jocić, Ana; Marić, Slađana; Trtić-Petrović, Tatjana; Gadžurić, Slobodan; Freire, Mara G.Aqueous biphasic systems (ABS) formed by copolymers and ionic liquids (ILs) have demonstrated to be effective separation platforms, but there is still a gap on the complete understanding of the molecular-level mechanisms ruling the two-phase formation for this type of systems. This work addresses the determination of the liquid-liquid equilibrium of ABS composed of cholinium-based salts or cholinium-based ILs a...
Valorization of expired energydrinks by designed and integrated ionic liquid-ba...
Dimitrijević, Aleksandra; Tavares, Ana P. M.; Almeida, Mafalda R.; Vraneš, Milan; Sousa, Ana C. A.; Cristóvão, Ana C.; Trtić-Petrović, TatjanaExpired energy drinks are rich in bioactive value-added compounds that can be recovered and reused in order to valorize food waste within a circular economy perspective. However, to accomplish such requirements, it is necessary to develop sustainable extraction and recovery processes, which must consist of decreasing the number of steps required or developing integrated strategies. In this work, novel aqueous b...
