Chemical Composition, Starch Digestibility and Antioxidant Capacity of Tortilla Made with a Blend of Quality Protein Maize and Black Bean

Tortilla and beans are the basic components in the diet of people in the urban and rural areas of Mexico. Quality protein maize is suggested for tortilla preparation because it presents an increase in lysine and tryptophan levels. Beans contain important amounts of dietary fiber. The objective of this study was to prepare tortilla with bean and assesses the chemical composition, starch digestibility and antioxidant capacity using a quality protein maize variety. Tortilla with bean had higher protein, ash, dietary fiber and resistant starch content, and lower digestible starch than control tortilla. The hydrolysis rate (60 to 50%) and the predicted glycemic index (88 to 80) of tortilla decreased with the addition of bean in the blend. Extractable polyphenols and proanthocyanidins were higher in the tortilla with bean than control tortilla. This pattern produced higher antioxidant capacity of tortilla with bean (17.6 μmol Trolox eq/g) than control tortilla (7.8 μmol Trolox eq/g). The addition of bean to tortilla modified the starch digestibility and antioxidant characteristics of tortilla, obtaining a product with nutraceutical characteristics

La fibra y sus beneficios a la salud

La fibra ha mostrado ser un componente de la dieta esencial para un estado óptimo de salud. El consumo de ésta se encuentra muy por debajo de las recomendaciones por lo que es de suma importancia promover su consumo. En este trabajo se abordan los aspectos más importantes y generales de la fibra dietética, los diferentes tipos y sus funciones, así como su importancia en la prevención de enfermedades no transmisibles como la diabetes, las enfermedades cardiovasculares, así como los desórdenes gastrointestinales y su efecto beneficioso en el control de peso corporal.Fiber is an essential dietary factor to maintain an optimal health status. Given that current fiber consumption does not achieve the recommended daily intake of fiber, the promotion of fiber intake becomes priority. In this work, the most relevant aspects regarding dietary fiber will be summarized, comprising a general overview, definition and functionality, its relevant role in prevention of noncommunicable diseases such as diabetes, cardiovascular diseases, as well as gastrointestinal disorders and weight management benefits
