Resumen
El estudio evaluó el impacto nutricional y antioxidante de tortillas de maíz azul fortificadas con 30% de harina de soya texturizada (proporción 70:30). Las determinaciones de composición química, antocianinas, fenólicos y actividad antioxidante total (ORAC y ABTS) se realizaron por triplicado. La fortificación favoreció incrementos significativos del 79% en proteína (11.37 a 20.36%), del 13.8% en cenizas (1.52 a 1.73%), del 32% en fenólicos totales (173.99 a 229.37 mg EAG/100 g) y del 20% en el potencial antioxidante determinado por ORAC (8,376.43 a 10,083.05 µmol ET/100 g) y ABTS (5,746.73 a 6,861.43 µmol ET/100 g), sin afectar la estabilidad de las antocianinas. La fracción fenólica insoluble superó el 84% del total, sugiriendo un potencial efecto prebiótico y antioxidante a nivel del colon. Estos hallazgos confirman que la soya texturizada es una estrategia tecnológica factible para fortificar tortillas tradicionales, ofreciendo una alternativa efectiva para mitigar deficiencias nutricionales y trastornos cardiovasculares.
