Diets very rich in cereals have been associated with micronutrient malnutrition, and the biofortification
of them, has been proposed as one of the best approaches to alleviate the problem. Durum wheat is one of the main sources of calories and protein in many developing countries. In this study, 46 durum varieties
grown under full and reduced irrigation, were analyzed for micronutrients and phytate content to determine
the potential bioavailability of the micronutrients. The variation was 25.7–40.5 mg/kg for iron and
of 24.8–48.8 mg/kg for zinc. For phytate determination (0.462–0.952 %), a modified methodology was
validated in order to reduce testing costs while speeding up testing time. Variation was detected for phytate: iron and zinc molar ratios (12.1–29.6 and 16.9–23.6, respectively). The results could be useful to
generate varieties with appropriate levels of phytate and micronutrients, which can lead to the development of varieties rich in micronutrients to overcome malnutrition.
