The graphical abstract systematically outlines the experimental design and major findings of this study. On the left is the conventional natural air‐drying method used as the control group; the middle section illustrates the Electrohydrodynamic (EHD) drying process under voltage gradients of 13, 17, and 21 kV, followed by four analytical dimensions ...

Green and Rapid Determination of Phthalates in Mineral Water From Virgin and Recycled PET Bottles
ABSTRACT This study investigates the presence and quantification of phthalates released into mineral waters from virgin and recycled polyethylene terephthalate (PET) bottles. A green, solvent‐free analytical method based on solid‐phase microextraction (SPME) coupled with gas chromatography–mass spectrometry (GC/MS) was developed and validated to detect

Evaluating Stabilizers Effects on Aroma Release Dynamics in Ice Cream: A PTR‐ToF‐MS Analysis
ABSTRACT Capturing the dynamic volatilome of frozen matrices during phase transitions remains an analytical challenge, typically requiring invasive sampling. This study employs proton transfer reaction time‐of‐flight mass spectrometry (PTR‐ToF‐MS) as a rapid, noninvasive technique that directly samples headspace volatiles without preconcentration to ...
