Inhibition Mechanism of Chitooligosaccharide-Polyphenol Conjugates toward Polyphenoloxidase from Shrimp Cephalothorax [PDF]
Crustaceans are perishable with a short shelf-life. They are prone to deterioration after capture, particularly during handling, processing, and storage due to melanosis caused by polyphenoloxidase (PPO).

Enzymatic polyphenoloxidase inactivation with temperature and ozone in sugarcane variety RB 92579 to produce lower color sugar [PDF]
Some sugarcane varieties have high activity of polyphenoloxidase enzyme, impairing the production of lower color sugar. Polyphenoloxidase (PPO) is an enzyme from the oxidoreductases group and it is present in a greater or lesser amount depending on the ...

4-Pentadecylpyridine: A Competitive Polyphenoloxidase Inhibitor [PDF]
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
