The aim of this work was to develop, for the first time, sustainable strategies, based on use Ultrasound-Assisted Extraction, Natural Deep Eutectic Solvents, and Pressurized Liquid extract proteins from lime (Citrus x latifolia) peels evaluate their potential release bioactive peptides. PLE showed largest extraction (66-69%), which were hydrolysed using three different enzymes (Alcalase 2.4 L FG, Alcalase®PURE L, Thermolysin). in vitro antioxidant antihypertensive activities released...
The potential of by-products generated during extra-virgin olive oil (EVOO) filtration as a natural source phenolic compounds (with demonstrated bioactivity) has been evaluated using pressurized liquid extraction (PLE) and considering mixtures two GRAS (generally recognized safe) solvents (ethanol water) at temperatures ranging from 40 to 175 °C. extracts were characterized by high-performance chromatography (HPLC) coupled diode array detection (DAD) electrospray time-of-flight mass...
A novel analytical method based on hybrid trapped ion mobility spectrometry-time-of-flight mass spectrometry (TIMS-TOFMS) has been developed to achieve fast enantiomeric separation of amino acids (AAs). Resolution chiral AAs was achieved by forming diastereomers through derivatization with the agent (+)-1-(9-fluorenyl)ethyl chloroformate (FLEC), avoiding use reference compounds. Electrospray ionization (ESI) in positive mode yielded sodiated FLEC-AAs ions which could be separated TIMS. The...
Cocoa powder is a highly consumed product all over the world which could be substituted by cheaper raw materials resulting in food fraud. In this work, non-targeted metabolomics approach based on use of reversed-phase liquid chromatography coupled to high-resolution mass spectrometry was developed carry out characterization cocoa samples adulterated, at two different levels, with carob flour, soy and chicory. The sample preparation protocol chromatographic parameters were optimized extract...
It is generally accepted that the selective binding of enantiomers chiral analyte to a selector necessary for enantioseparations in CE, whereas role mobility differences between temporary diastereomeric associates formed and has been commonly neglected. One authors this study suggested 1997 difference two with may be solely responsible separation CE enantioselective selector-selectand not necessarily required. Several indirect confirmations hypothesis have described literature within last...
