This study was realized with the aim to assess the nutritional quality of fortified cookies with. bovine whole blood spray dried (SBSA). Proximal composition, iron content, Protein Efficiency Ratio (PER), Apparent Protein Digestibility in vivo (DA), acceptability percentage and sensorial qualities was determined. lt was tested two levels of cookies fortification: 5% (G5) y 8% (G8) and a control group of unfortified cookies (G0) The dehydration yield was 150 grams of SBSA by liter of blood. it was found that the SBSA has a high content of protein (83,71 g/100g) and iron (385,20 mg/100g). The results of microbiologic analysis of the cookies showed that they were adequate for human consumption. The G8 cookie had the highest protein content (13,07 g/100g), fóllowed by the G5 cookie (10,99 g/100g), and at last GO cookie (8,72 g/100g); similar tendency was observed for iron content: G8 (24,04 mg/100g), GS (20,96 mgílOOg) y GO (8,32 mg/100g). The DA of G5 (88,0 %) and G8 (88,7 %) cookies were statistically similar and smaller than the DA of casein (94,2%). The PER of cookie G8 (1,43) was statistically higher than G5 cookie (1,27), both fortified cookies had a lower PER than casein (3,10). In the sensorial test, it was found significant differences between the averages of the flavor score (GO=3,62, G5=3,18 y G8=3,08) and general appreciation (GO=3,60, G5=3,02 y G8=2,56); in contrast, there was not significant differences between the averages of the odor score (GO=3,34, G5=3,18 y G8=3,08). The GO was the cookie with. the highest acceptability percent (40/o), continued by the G5 cookie (35% and in the last place the G8 cookie (25%). it was concluded that fortification of cookies with bovine whole blood spraydried (SBSA) increases notably the protein and iron content. The cookies fortified with SBSA present high protein digestibility and his values of PER are similar to that of other baked cookies. Of two levels of fortification tested in the present work (5 % and 8 %), the most suitable level of fortification would be that of 5 % (G5), since these cookies show major acceptability and major score of flavor and general appreciatiún that the cookies fortified to 8 % (G8).
