A type of technological study was realized with aim to determine the nutritional quality of an extruded product fortified with two levels of iron from a bovine blood meal. Two levels of fortification 10i% and 15i% was formulated. Also an unfortified extruded product (0i%) was used as a comparison sample. Bovine blood meal was obtained from a spray drying and for obtaining the extruded product was used a screw extruder. Nutritional quality was determined from the iron content, proximate analysis, physicochemical, microbiological and test acceptability by sensory evaluation. The extruded products fortified with 10i% and 15i% of iron from the bovine blood meal, had a high iron content (31,87 mg/100 g and 38,08 mg/100 g respectively) as opposed to a lower iron content in the extrudate without fortify (0i%) which was 2,99 mg/100 g. Respect to microbiological analysis indicated that the extruded products were fit for human consumption. The acceptability testa was conducted ina an educational institution with two types of panels: panel Nºi1 (30 students from 5 to 6 years old) was presented a 3-point hedonic scale and there were no significant difference between the three samples of extrudeda(p <0,05)a anda panel Nºi2 (30 students from 13 to 15 years old) was presented a 5-point hedonic scale and there were significant differences between samples of extruded products with a level of fortification of 0i% and 15i% (p<0,05). In conclusion, the extruded product fortified with 10i% of iron from bovine blood meal showed an adequate nutritional quality and was more acceptable than the extruded product fortified with 15i% of iron from the bovine blood meal. Keywords: bovine blood meal, extruded product fortified, nutritional quality.
