    Abstract:
    Storage, at high temperature (> or = 25 degrees C) and high relative humidity (> or = 65%), causes development of hard to cook (HTC) phenomenon in grain legumes. The objective of this work was to study the effect of storage simulating tropical conditions on chickpeas quality. The hardening of the Surutato 77, Mocorito 88, and Blanco Sinaloa 92 chickpea varieties was produced using adverse storage (32 +/- 1 degrees C, RH = 75%, 160 days) conditions. For all samples, the Hunter 'L' values decreased and deltaE values increased during storage, meaning a loss of color lightness and development of darkening. Accelerated storage caused a significant decrease in the water absorption capacities and cooking times of whole seeds, cotyledons and seed coats of all samples, being more pronounced in The Blanco Sinaloa 92 variety. Furthermore, storage produced significant decreases in the seed coat tannin content of the three materials; this parameter increased significantly in the cotyledon. In all samples, the levels of phytic acid decreased significantly with the seed hardness. Hardening of chickpea grains caused a decrease in the in vitro protein digestibilities of all varieties. These results suggest that both the cotyledon and seed coat play a significant role in the process of chickpea hardening. Blanco Sinaloa 92 and Mocorito 88 might be classified as varieties with high and low proneness, respectively, to the development of the HTC condition.
