The key role of catechol oxidase in enzymatic browning makes it a common target for inhibition. While a number of inhibitory strategies exist such as high temperature treatments(70-90 °C) to eliminate catechol oxidase catalytic activity, [6] a popular strategy is decreasing the pH with citric acid. Catechol oxidase is more catalytically active ...
There are three structural isomers: 1,2-dihydroxybenzene (the ortho isomer) is commonly known as catechol, 1,3-dihydroxybenzene (the meta isomer) is commonly known as resorcinol, and 1,4-dihydroxybenzene (the para isomer) is commonly known as hydroquinone. [1]

Thus, the two substrates of this enzyme are catechol and O 2, whereas its two products are [[dibenzo[1,4]dioxin-2,3-dione]] and H 2 O. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with oxygen as acceptor. The systematic name of this enzyme class is catechol:oxygen oxidoreductase ...

When the surface of apples are exposed to the oxygen in the air, the oxidative enzymes like polyphenol oxidase and catechol oxidase oxidize the fruit (electrons are lost to the air). Such browning can be prevented by cooking the fruit or lowering the pH (which destroys, inactivates, or denatures the enzyme) or by preventing oxygen from getting ...
