Maillard reaction
Noun
Meaning
Maillard reaction (plural Maillard reactions)
(organic chemistry) The condensation reaction of an amino acid and a reducing sugar, followed by polymerization to form brown pigments - melanoidins; one of the causes of browning during cooking. [from 1910s]
Examples
Because fructose exists to a greater extent in the open-chain form than does glucose, the initial stages of the Maillard reaction occur more rapidly than with glucose.
However, some reactions such as the Maillard reaction that produces "browning" and associated flavors during roasting or frying, require temperatures higher than are found in a pressure cooker.
Chemical processes central to cooking include the Maillard reaction – a form of non-enzymatic browning involving an amino acid, a reducing sugar and heat.
It is hardened and browned through the Maillard reaction using the sugars and amino acids and the intense heat at the bread surface.
Pre-frying ingredients e.g. meat in the open pressure cooker can achieve the Maillard reaction.
The cooling process helps stop the milk from undergoing the Maillard reaction and caramelization.
