Utilization of Kanawa (Chenopodium pallidicaule Aellen) Flour in Pasta Making
Kanawa (Chenopodium pallidicaule Aellen) is an Andean crop harvested in Bolivia and Peru. Because of the characteristics and properties of kanawa seed, its flour can be used to replace partially wheat flour in pasta to increase its nutritional value. The objective of this study was to investigate the production of fiber and protein enriched pasta made with wheat and kanawa blends. The effect of the substitution level of wheat by kanawa flour on pasta quality was evaluated taking into account the influence of kanawa composition on starch behavior and gluten network formation. Proximal composition, thermal behavior, and pasting properties of kanawa and wheat flours were determined. Pasta was made from wheat flour (control) replacing 10, 20, and 30% of wheat by kanawa flour from L1 and L2 ecotypes. Water absorption and cooking loss were increased showing the deleterious effect of kanawa flour on pasta quality, but the L1 ecotype showed better performance in cooking properties. Kanawa pasta firmness and chewiness decreased with the kanawa content increase; however, the L1 ecotype did not modify the firmness when 10 and 20% were included in pasta. Both kanawa flours improved the nutritional quality of pasta, increasing the dietary fiber content and protein quality.
