Thermally treated corn bran (TTCB) presented 8.94% of moisture, 2.22% of ashes, 9.73% of proteins, 9.37% of lipid and 33.80% total dietary fiber. In addition, 73.21% of TTCB exhibited granulometry < 250 µm and 14 weeks of shelf-life. TTCB altered dough rheological properties, decreasing stability and dough development time, while increasing mixture tolerance index. Moreover, TTCB did not significantly alter the extension strength, leading to a diminishment in extensibility and an increase of dough curve configuration ratio, which characterizes a flour considerably resistant to extension, a desirable factor for tagliarini elaboration. Pasta quality test staged that TTCB incorporation in up to 14.53% has increased cooking period and volume, decreasing solids' loss. In addition, TTCB enhanced dough firmness and adhesiveness, reducing hardness and shear work. http://pubs.sciepub.com/jfnr/6/2/10/jfnr-6-2-10.pdf corn bran shelf-life rheological analysis tagliarini pasta dough quality
