Maillard reaction

A non-enzymatic heat-activated chemical reaction between sugars (especially ribose) and amino acids, which occurs in foods as they form glycosylamines and Amadori compounds. The Maillard reaction is responsible for “browning” of baked or cooked foods (e.g., bread crusts and barbecued steak), which are mutagenic by the Ames assay.

It is possible that the age-related changes in collagen are partially mediated through the Maillard reaction; it has been suggested that a similar, if not identical, reaction is involved in certain neurodegenerative diseases—e.g., Alzheimer’s, Creutzfeldt-Jakob and Parkinson’s diseases.

Maillard reaction

A chemical reaction between sugars and proteins that results in cellular damage or aging; the making of advanced glycosylation end products; the chemical deterioration of proteins during food processing or storage. Also known in nutritional science as the “browning reaction.”
