“…Table 1 below shows the summary of the main results of the thermal analysis that was carried out in the oven. These results are good compared to other devices, due to the thermal parameters and their versatility due to their size [22,23].…”

“…For people who use traditional stoves, it is economical because they can use less forest biomass or other types of energy that have a cost, unlike solar energy, which is free. There are other corns in Mexico with a higher content of antioxidants that can be treated with solar processes to preserve their properties in such a way that they can be compared with dry extracts of medicinal plants and food supplements [9,10,22] when performing similar analyses to this. The consumption of food from endemic inputs has now been devalued in Mexico and other countries.…”

“…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].…”

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.
