Abstract: The Maillard reaction consists of a set of interactions between a reducing sugar and an amino group (which can come from amino acids, peptides or proteins). This reaction takes place during the cooking of food. The Maillard reaction is of utmost importance, since thanks to it, aromas, flavors and pigments are generated that are part of the characteristics of cooked foods. In this work we present the results we obtained by developing an experiment that illustrates the formation of pyrroles from the reaction of two carbohydrates, glucose or fructose, with two primary amines: benzylamine or n-butylamine, to illustrate the Maillard reaction to the students of the food chemistry course taught at this Faculty, in the subject Organic Chemistry III (key 1628) which is taught in the 6th grade. semester of this degree. Two heating sources were used, conventional using a heating grill to heat under reflux, or microwave radiation using a microwave reactor. The products obtained were 2-carboxaldehyde-5-hydroxymethyl-1-n-butylpyrrole or 2-carboxaldehyde-5-hydroxymethyl-1-benzylpyrrole, which were characterized based on their spectroscopic properties.
