Calidad de nixtamal y tortilla en genotipos de maíz [Zea mays L.] mejorados para el trópico húmedo de México

With the objective of evaluating physical and chemical characteristics and tortilla quality for maize improved genotypes for the humid tropic in Mexico, during fall winter season 2023/24 under irrigation conditions there were evaluated seven maize genotypes from Cotaxtla experiment station, INIFAP; These genotypes were produced in plots of 4 rows 5 m long and 80 cm wide in plant density of 62,500 plants ha-1 ; The grain humidity varied from 10.5-12.2 %, this humidity is an advantage for storage because reduce fungus proliferation. All seven genotypes registered hectoliter pound between 75 and 78.6 kg hL-1 , with hard and intermediate endosperm, both characteristics into the norm specifications NMX-034/1, these genotypes can be processed by the traditional Nixtamalization and floury industries. V-537C registered 1.63 kg of tortilla for each kg of maize grain and presented intermediate hard endosperm and there were produced soft tortillas, Finally, V-537C presented the highest content of Lysine but not for Tryptophane content.
