Understanding protein–flavor interactions: Factors, characterization techniques, and the effect of processing

open access: yesFood Biomacromolecules, EarlyView.
Abstract The perception of flavor in a food system depends on its release from the protein matrix. Apart from hydrogen bonding, hydrophobic interactions and van der Waal's forces, the formation of covalent adducts between the flavor and protein highly impacts the release of flavor from the protein matrix.

Synthesis of anethole from propylphenol.

open access: yesNIPPON KAGAKU KAISHI, 1990
p-Propylphenol was coverted to p-methoxyphenylpropane and then oxidized with lead tetraacetate in acetic acid to give anethole. The synthetic route may be general for a-acetoxylation of the side chain of alkylphenol derivatives. Intermediate α-acetoxylated compounds were also isolated and their 'H- and 13C-NMR spectra were presented together with those

Practical Applications of Secondary/Extractive Electrospray Ionization (SESI): A Versatile Tool for Real‐Time Chemical Analysis

open access: yesMass Spectrometry Reviews, Volume 45, Issue 2, Page 392-428, March/April 2026.
ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry
