ABSTRACT
Talking about maize in Mexico means history, tradition, legacy, economic, political, and social organization, and above all, identity. Mexico is recognized as the center of origin and diversification of maize. In addition to its economic importance and varied industrial applications, maize constitutes the basis of the diet of the indigenous communities of Latin America, being tortillas as its main form of consumption. To obtain tortillas, maize goes through a nixtamalization process in which at least 3 m3 of wastes are generated for each processed ton of corn. Usually, these wastes are disposed of through the municipal drainage system without 34any treatment or management. For this reason, it is necessary to develop bioprocesses that allow handling and revaluation of this residue, nejayote, because it contains grain-specific residues such as polyphenols, sugars, gums, and calcium components, which could have important applications for the food and pharmaceutical industries.
