Browning is the process of food turning brown due to the chemical reactions that take place within. The process of browning is one of the chemical reactions that take place in food chemistry and represents an interesting research topic regarding health, nutrition, and food technology. Though there are many different ways food chemically changes ...
Aesculus hippocastanum is a large tree, growing to about 39 metres (128 ft) tall [9] with a domed crown of stout branches. On old trees, the outer branches are often pendulous with curled-up tips.

Gnomoniopsis castaneae (synonym Gnomoniopsis smithogilvyi) is a fungus of the order Diaporthales [2] that is the most important cause of brown chestnut rot, [3] an emerging disease [4] that damages the fruit of chestnuts. It also causes cankers and necrosis on leaves and on chestnut galls caused by the gall wasp ...
The Maillard reaction (/ maɪˈjɑːr / my-YAR; French: [majaʁ]) is a chemical reaction between amino acids and reducing sugars to create melanoidins, the compounds which give browned food its distinctive flavor. Seared steaks, fried dumplings, cookies and other kinds of biscuits, breads, toasted marshmallows, falafel and many other foods ...
It is commonly seen in the enzymatic browning of fruits such as bananas. Chestnut shell melanin can be used as an antioxidant and coloring agent. [50] Biosynthesis involves the oxidation of indole-5,6-quinone by the tyrosinase type polyphenol oxidase from tyrosine and catecholamines leading to the formation of catechol melanin. Despite this ...
