In this work, the transgenic corn grain 2B587 Hx presented
higher contents of carbohydrates and ash and a lower content of
crude fibers relative to its conventional isoline 2B587. Peleg's model
presented a good fit to the experimental hydration data for both
cultivars with high coefficients of determination and the generalized
model presented a maximum deviation of approximately 10%.
The study of the water absorption kinetics showed the behavior of
the cultivars during hydration process. The constant k1 in Peleg's
model is inversely proportional to initial hydration rate and the
model predicts an increase in the rate of water absorption by the
grains as the temperature increases. In average, the hydration rate
of the conventional corn grain 2B587 was 9% higher than that of the
transgenic corn grain 2B587 Hx according to the constant k1 in
Peleg's model, suggesting lower hydration times for the corn grain
2B587. The cultivar may be chosen according to the specifications
required by the industry for the main final products
