Green Ultrasound-Assisted Dispersive Liquid-Liquid Microextraction Coupled to GC-MS for Simultaneous Determination of Lipid-Peroxidation- and Maillard-Derived Carbonyl Compounds in Plant-Based Beverages.

ABSTRACT: Carbonyl compounds generated through lipid peroxidation and Maillard-type reactions are relevant markers of food quality and safety due to their potential toxicity and prevalence in processed plant-based beverages. This work presents the development and validation of a green, ultrasound-assisted dispersive liquid-liquid microextraction (UA-DLLME) method using sustainable extractant (isobutyl acetate) and dispersant (isopropanol) solvents for the simultaneous determination of 12 carbonyl compounds across multiple chemical families (aldehydes, ketones, furans, and dicarbonyls). The method integrates in situ derivatization with O-(2,3,4,5,6-pentafluorobenzyl) hydroxylamine hydrochloride and gas chromatography-mass spectrometry (GC-MS) analysis. Method optimization was performed using a
