The main difference between Maillard reaction and caramelization is that Maillard reaction is non-pyrolytic, whereas caramelization is pyrolytic.
Maillard reaction and caramelization reactions are two reactions that occur during cooking. They contribute to the color, aroma, and flavor of many foods.

What is Maillard Reaction?
Maillard reaction is an organic chemical reaction in which reducing sugars react with amino acids to form a complex mixture of compounds. It is a non-pyrolytic reaction. This reaction results in the characteristic flavor and aroma of browned food. Also, this reaction is considered a non-enzymatic browning reaction. The optimum temperature range for this reaction is between 140 degrees Celsius and 165 degrees Celsius.
Moreover, the mechanism of the Millard reaction involves a few steps. Firstly, the reaction between the amino group of the amino acid and the carbonyl group of the reducing sugar forms an N-substituted glycosamine (along with water). Then, the Amadori rearrangement transforms glycosamine into ketosamines, which undergo many other reaction pathways to form reductones, butanedione, methylglyoxal, and many other products. Ketosamines can form melanoidin and other brown nitrogenous polymers, giving a characteristic brown color to the food.
The formation of caramel from sugar and milk, browning of bread during the preparation of toast, and change in color when cooking condensed milk are examples of instances where the Maillard reaction occurs.
What is Caramelization
Caramelization is the oxidation of sugar. It is a pyrolytic reaction. It is also a process used extensively in cooking. Caramelization gives a nutty flavor and brown color to food. Furthermore, it is a type of non-enzymatic browning reaction. This process releases volatile chemicals, which produce a characteristic caramel flavor. However, the caramelization reaction depends on the type of sugar. The most common sugars used for caramelization are sucrose, glucose, and fructose. Sucrose, which is a disaccharide made up of glucose and fructose, requires higher temperatures to caramelize. Meanwhile, glucose and fructose require lower temperatures to caramelize. The process of caramelization can be divided into three stages: the melting stage, the dehydration stage, and the pyrolysis stage. Caramelization takes place at about 165 degrees centigrade.
There are several factors that determine the final color and flavor of caramelization, such as the type of sugar being used, temperature, and the duration of the heating process. Caramelization may give a color ranging from light golden brown to dark brown color. Here, the degree of caramelization affects the intensity of the flavor and aroma. The light-colored sugars have a sweet, nutty flavor with a light brown color. The darker caramelization sugars have a more complex flavor with a dark brown color.
Adjusting the temperature, adding other ingredients such as water and acid, and the duration of the heating process can control the degree of caramelization.
Caramelization is used in the food industry to add flavor and color to a variety of products, such as baked goods, sauces, and confectionery. It is also used in the production of caramelized sugar, which is a common ingredient in food products like ice cream, candies, and baked goods. The caramelization process is also useful in the production of pharmaceuticals, cosmetics, and industrial chemicals.
Difference Between Maillard Reaction and Caramelization
Maillard reaction is an organic chemical reaction in which the reducing sugars react with amino acids to form a complex mixture of compounds, while caramelization is a chemical process that takes place involving sugar in the food.
The reactants of Maillard reactions are amino acids and reducing sugars, whereas the reactants of caramelization are sugars in the food.
The Maillard reaction is a non-pyrolytic reaction, whereas caramelization is a pyrolytic reaction.
While the Maillard reaction takes place at around 140 degrees to 165 degrees Celsius, caramelization takes place above 165 degrees Celsius.
Maillard reaction and caramelization are two chemical reactions that occur during cooking and contribute to many foods’ color, aroma, and flavor. The main difference between Maillard reaction and caramelization is that the Maillard reaction is non-pyrolytic, whereas caramelization is pyrolytic.
