Fortification and bioavailability of zinc in potato.

Victor Manuel Vergara Carmona, Arthur Bernardes Cecílio Filho, Hilário Júnior de Almeida, Priscila Lupino Gratão
Most agricultural soils have low zinc (Zn) content available to crops, which results in a significant decrease in productivity and in public health problems. However, the priming of potato tubers in solutions with Zn can be an effective strategy for their fortification. In order to evaluate the effect of Zn concentrations and tuber priming time on the fortification and bioavailability of Zn, potato tubers were primed in solutions containing 0, 10, 20 and 30 mg mL-1 Zn during 12, 16, 20, and 24 hours, respectively. The dry matter and the content of Zn and phytic acid (PA) in tubers were assessed in order to obtain the PA:Zn molar ratio.
