Abstract

Maillard reaction (MR) is nonenzymatic browning that occurs in foods and living organisms between the carbonyl group of reducing sugars and amino group of proteins. The reaction forms compounds which are responsible for the transformations of flavor, color, taste and texture of foods submitted to a thermic processing. These transformations are determinants for the consumer choice. However, harmful compounds can be generated during the MR, like acrolein,acrylamide, heterocyclic aromatic amines. The final stages of MR, in foods and living organism (glycation), lead to formation of advanced glycation endproducts (AGEs) that have been related to the development and emergence of various diseases like diabetes, renal failure and atherosclerosis. Consumption of fried or highly processed foods, like fast foods, has increased in the last decades and has been a concern of the scientific community about harmful effects caused by the Maillard reaction products (MRP). MR also generates fluorescent compounds that are considered important markers of MR. The extent of Maillard reaction can be established through methods of absorbance. This study proposes to indicate the influence of the some types of thermic processing, employed during home cooking of bovine meat, in the progressivity of Maillard reaction, contributing to the estimation of the most appropriate types of processing to minimize the harmful effects on the population, particularly the most vulnerable who have diseases resulting from glycation.
