The present study had the objective of developing a cereal bar containing prebiotics and a higher quantity of protein and minerals, using two Non-Conventional Food Plants (PANCs): the ora-pro-nobis (Pereskia aculeata Mill) of tropical origin, that contains a high protein, fiber, iron and calcium content; and Yacon (Smallanthus sonchifolius) - with Andean origin, which presents high content of fructan, such as inulin and fructooligosaccharides (FOS). With increased protein, fiber, calcium and iron source the cereal bar formulated with PANCs can contribute to the reduction of caloric intake, attending the specific needs of people with metabolic and physiological conditions, collaborating with the prevention of obesity, iron deficiency anemia and osteoporosis. The leaves flour of ora-pro-nobis (FOPN) and the Yacon flour (FY) were characterized regarding the centesimal composition. The cereal bars were development in the ratio of 51:49 to dry ingredients and binders and after, partial replacement by flour of leave ora-pro-nobis (FOPN) and yacon (FY) flour was done. The PANC's cereal bar (B-PANC) had a significant increase in the iron content, when compared to the control bar (B-CTL), characterizing it as a source of this nutrient, it is able of providing 24% of the RDI for this mineral. The B-PANC received 35.2% acceptance and with 40.9% of the volunteers possibly buying due to the functional and health claim of the product. The bioaccessibility of the minerals was analyzed (Iron, Calcium, Magnesium and Zinc) and observed an increase in the total concentration of the minerals, but in the bioaccessible fraction, there was no significant difference.
