    Flour is one of the central products for the production of functional foods, in Ecuador there are several crops with quality nutritional content, however, they are undervalued and no studies have been conducted to exploit their benefits. On the other hand, lipids are a fundamental part for the correct metabolic functioning, however, their excessive consumption is not recommended for health. For this reason, the present study evaluates the lipid profile of chocho and white melloco flour, in order to determine if the fat content in these matrices will allow the formation of products that provide health benefits to the Ecuadorian population. Fatty acids were determined with FID gas chromatography, in which 7 fatty acids were identified in chocho; palmitic acid (10.38 percent), oleic acid (51.92 percent), linoleic acid (40.43 percent), linolenic acid (2.45 percent), stearic acid (3. 17 percent), behenic acid (0.92 percent), arachidic acid (0.73 percent); while, the lipid profile of melloco recognized 4 fatty acids; palmitic acid (15.43 percent), oleic acid (5.92 percent), linoleic acid (71.94 percent), linolenic acid (6.71 percent). In addition, nutritional quality indices omega 6: omega 3 (12.42; 10.72), PUFA:SFA (2.16; 5.08) and atherogenicity (0.12;0.18) were performed on chocho and melloco blanco, respectively.
