Preservation of Antioxidant Properties of Endemic Dark Corn Using Solar Energy for Nixtamalization

A comparative study of two corn nixtamalization processes is presented, one in the traditional way Michoacan region Mexico, and other using solar devices. The selected for process was a nontransgenic endemic dark corn. For process, concentration oven used; this device simple affordable communities. characterization, properties antioxidant content were analyzed both processes, highest antioxidants between varieties obtained. capacity black quantified determined, anthocyanin pigments extracted with methanol. total (CAT) evaluated by pH difference method, DPPH method. In higher CAT anthocyanins Therefore, energy proposed as sustainable option, we concluded that nixtamalized had high levels could be used nutritious food.
