Maillard reaction describes what?

• A. Caramelization of sugars only
• B. Reaction between amino acids and reducing sugars producing browning and flavor
• C. Purely sugar caramelization
• D. Evaporation of water

Answer: (B)

The Maillard reaction is a non-enzymatic browning process that happens when reducing sugars react with amino groups in amino acids or proteins under heat. This reaction creates browning and a wide range of complex flavors and aromas, giving us the roasted, grilled, and savory notes we associate with cooked meat, bread crusts, and roasted coffee. It’s different from caramelization, which involves sugars breaking down on their own to brown and develop sweetness, without amino acids. Water evaporation isn’t what drives Maillard browning; moisture levels influence the rate, but the browning comes from the chemical interaction between sugars and amino groups that forms new compounds and pigments.
