Maillard Reactions in Chemistry, Food and Health

The control of Maillard reaction in white grape molasses by the method of reducing reactant concentration. HMF accumulation was lower in the grape juices which were treated with Amberlite or activated carbon throughout the boiling. Dowex was more effective than Amberlite in controlling of brown pigment formation. Analysing the results of HMF and brown pigment, activated carbon was the best resin to control the Maillard reaction. Maillard reaction is defined, with a general expression, as the reaction between the carbonyl and amino groups Oh et al.

Browning, or the Maillard reaction, creates flavor and changes the color of food. Until the Maillard reaction occurs meat will have less flavor. Like caramelization, it is a form of non-enzymatic browning. The reactive carbonyl group of the sugar interacts with the nucleophilic amino group of the amino acid, and interesting but poorly characterized odor and flavor molecules result. This process accelerates in an alkaline environment because the amino groups do not neutralize.

Seared steaks, fried dumplings, cookies and other kinds of biscuits, breads, toasted marshmallows, and many other foods undergo this reaction. It is named after French chemist Louis Camille Maillard , who first described it in while attempting to reproduce biological protein synthesis. Many recipes call for an oven temperature high enough to ensure that a Maillard reaction occurs. The reactive carbonyl group of the sugar reacts with the nucleophilic amino group of the amino acid and forms a complex mixture of poorly characterized molecules responsible for a range of aromas and flavors. This process is accelerated in an alkaline environment e. This reaction is the basis for many of the flavoring industry's recipes. At high temperatures, a probable [4] carcinogen called acrylamide can form.

The Maillard reaction was originally studied due to its importance in foods. Lately, it has been found to play a key role in many health-related issues. It is now associated with diabetes, ageing and cancer. This volume of conference proceedings presents recent research and discusses aspects of the chemistry, kinetics, technology and toxicology of this reaction.

The Maillard reaction occurs widely in food and biological systems. This contribution reviews the relation between the Maillard reaction and food processing, particularly its contribution to flavor formation, antioxidative effects, desmutagenic activity and the improvement of protein functional properties. Proteins modified by glucose, and melanoidins are important components of foodstuffs while the reactions of amino acids or peptides with glucose or dicarbonyl compounds produce various kinds of flavor components. Melanoidins and Amadori rearrangement products play an important role in providing antioxidative effects, both in vitro and in vivo. Melanoidins also exhibit desmutagenic activity against carcinogenic compounds. Protein-polysaccharide conjugates, prepared by Maillard reaction at mild conditions, increase the emulsifying activity, as well as antioxidative and antimicrobial effects of the original proteins.

Maillard reaction

Pirassununga- SP, Brazil. Deep-fat frying is widely used in food industries because of its low cost and high demand, since it produces convenient food of high acceptability. The process is based on the oil-food interaction at high temperatures, which cooks and dehydrates the food, leading to physical and chemical changes, such as starch gelatinization, protein denaturation, flavoring and color production via Maillard reaction. Some food and oil compounds are lost in the frying process, and potentially toxic compounds are developed in the oxidized oil. Although widely studied, many of these compounds have not been fully identified.
