Flour blends (FB) based on wheat flour with partial substitution for isolated soy protein, powdered whey and three corn flour types (common or cultivar BR451 and BR2121) were prepared to improve the protein quality of wheat flour. The sensory and chemical characteristics of the cookies were evaluated and the potential proteic value was calculated. The results were compared with the wheat flour or its cookie (controls). Macronutrients levels in FB and cookies were superior than those in the respective controls, except for carbohydrates. Only in the appearance the cookie made with FB BR2121 was statistically inferior to the one with common corn FB, being similar to the control and other cookies in texture and flavor. The cookie with common corn FB had the highest acceptance. Cookies mean caloric value was 436kcal. The proteic quality of the FB cookies - lysine and threonine as limiting essential amino acids and C-PER about 2 - was superior than the control. The baked FB cookies cost (price/kg) was superior than the control, because the FB cost was about the double of the wheat flour and also the necessity to use higher quantities of ingredients in the formulation.
