The present research had the objective to develop biscuits with mixed flour of fermented cassava starch and orange albedo flour, using a 23 factorial experimental. The independent variables were: concentration of fermented cassava starch, sugar and orange albedo flour, and the responses variables were the sensory characteristic: appearance, aroma, texture and flavor, in addition to overall impression, using a nine point hedonic structure scale. The biscuits were also evaluated for physic-chemical properties. The average for sensory characteristic were in the range of five (not liked nor disliked) up to seven (like moderately), and it didn't show significant difference (P size="2">≤ face="Verdana, Arial, Helvetica, sans-serif" size="2">0.05) for all sensory characteristics assessed. Thus, it was possible to choose the optimal formulation obtained according with the nutritional parameters, because there isn't sensory difference significant, which was: 35% of fermented cassava starch, 100% of sugar and 7.5% of orange albedo flour. In comparison with the commercial biscuits test, standard and optimized, sensory appearance, flavor and texture showed significant differences (P size="2">≤ face="Verdana, Arial, Helvetica, sans-serif" size="2">0.05). The results correspond to standards set by Brazilian legislation, and crude fiber content of the biscuit was optimized at 3.08%, thus, can be classified as biscuit "source of fiber".
