Role of Chlorogenic Acid Quinone and Interaction of Chlorogenic Acid Quinone and Catechins in the Enzymatic Browning of Apple [PDF]

Bioscience, Biotechnology, and Biochemistry, 2011
Chlorogenic acid (CQA) is one of the major polyphenols in apple and a good substrate for the polyphenol oxidase (PPO) in apple. Apple contains catechins as well as CQA, and the role of CQA quinone and its interaction with catechins in the enzymatic browning of apple were examined.

Harnessing the Interfacial Activity of Soluble Faba Protein‐Tannic Acid Conjugates for Enhanced Lipid Oxidative Stability of Oil‐in‐Water Emulsions

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT In oil‐in‐water emulsions, lipid oxidation begins at the interface between the two phases. One strategy to slow down this process is to place antioxidants at the interface, where they can directly block oxidative reactions. This study explored that idea by conjugating soluble faba bean protein with tannic acid using the free‐radical grafting ...
