TL;DR: The key role of the interfacial region and of its composition in interpreting the efficiency of AOs in inhibiting lipid oxidation in emulsions is highlighted, and a careful modulation of these parameters is necessary to ensure optimum AO efficiency.

TL;DR: In this paper, a series of caffeic acid derivatives bearing the same reactive moiety but of different hydrophobicity (alkyl chain lengths of 1 to 16 carbon atoms) were used to investigate the effects of hydophobicity on the oxidative stability of stripped corn oil-in-water emulsions.

Kinetics and Mechanism of the Reaction between an Arenediazonium Ion and Methyl Gallate (=Methyl 3,4,5-Trihydroxybenzoate) in Aqueous Solution: Evidence for Diazo Ether Formation through an O-Coupling Reaction
TL;DR: In this article, the authors investigated the kinetics and mechanism of the reaction between 3-methylbenzenediazonium ions (3MBD) and methyl gallate (MG), in aqueous buffer solution by employing spectrophotometric (UV/VIS) and electrochemical (linear-sweep voltammetry, LSV) techniques and computational methods.

Distributions of phenolic acid antioxidants between the interfacial and aqueous regions of corn oil emulsions: Effects of pH and emulsifier concentration
TL;DR: In this article, the authors investigated the effects of pH on the partition constant, PWI, and the distribution of two phenolic acid AOs, gallic (GA) and caffeic (CA), between the aqueous and interfacial regions, in emulsions of 1:9 (vol:vol) corn oil/acidic water and Tween 20.
