Effect of pH and temperature on peroxidase and polyphenoloxidase activities of litchi pericarp Efeito do pH e da temperatura nas atividades da peroxidase e polifenoloxidase do pericarpo de lichia

open access: yesScientia Agricola, 2010
After harvesting litchi, the red color of the fruit pericarp is rapidly lost resulting in discoloration and browning during storage and marketing. The loss of the red color is caused by the degradation or loss of stability of anthocyanins.

Protein–phenolic interactions and reactions: Discrepancies, challenges, and opportunities

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 23, Issue 5, September 2024.
Abstract Although noncovalent interactions and covalent reactions between phenolic compounds and proteins have been investigated across diverse scientific disciplines, a comprehensive understanding and identification of their products remain elusive. This review will initially outline the chemical framework and, subsequently, delve into unresolved or ...

4-Pentadecylpyridine: A Competitive Polyphenoloxidase Inhibitor

open access: yesZeitschrift für Naturforschung C, 1997
Abstract 4-Pentadecylpyridine was isolated from plums infected by Taphrina pruni. This fungal metabolite has been tested for its effect on polyphenoloxidase, using the polyphenoloxidase-catalysed addition of L-proline to 4-methylcatechol in a chromogenic assay The resulting data prove that 4-pentadecylpyridine is a competitive inhibitor
