“…The design of the solar oven was based on previous studies that were carried out for the implementation in Michoacán [18][19][20][21][22] that used a compound parabolic concentrator (CPC) of revolution and a solar oven [23] based on a CPC channel. The oven is a device that offers users safe operation because it uses anidolic, i.e., out-of-focus, optics to avoid flashes that can damage users' eyesight [24].…”

“…In Latin America, solar stoves have been implemented in Bolivia, Chile, Peru and Argentina. In Michoacán, solar stoves have also been implemented in indigenous and rural communities [18,19]. The implementation projects that have been carried out in Michoacán are changing according to the needs of the users, without neglecting the scientific vanguard [20].…”

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

et al. 2021

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