The second type of browning, non-enzymatic browning, is a process that also produces the brown pigmentation in foods but without the activity of enzymes. The two main forms of non-enzymatic browning are caramelization and the Maillard reaction.
The crusts of most breads, such as this brioche, are golden-brown mostly as a result of the Maillard reaction.. The Maillard reaction (/ m aɪ ˈ j ɑːr / my-YAR; French:) is a chemical reaction between amino acids and reducing sugars to create melanoidins, the compounds that give browned food its distinctive flavor.
Preventing the browning from occurring is essentially an effort to slow down the enzymatic reaction of the fruit, Keathley says. Thus, “finding a method to block the enzyme from working properly ...
PPO has importance to the food industry because it catalyzes enzymatic browning when tissue is damaged from bruising, compression or indentations, making the produce less marketable and causing economic loss. [31] [32] [33] Enzymatic browning due to PPO can also lead to loss of nutritional content in fruits and vegetables, further lowering ...

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 ...
Browning is typically done using a frying pan, which is generally preheated to a medium high temperature to avoid sticking. In order to brown properly, the meat should first have surface moisture removed. This is usually achieved by patting the meat with a paper towel to remove water. [1] [page needed]
