Gérmen com pericarpo de milho desengordurado na formulação de biscoitos tipo cookie

Resumo

The germ with pericarp, byproduct of corn grain processing, has a high nutritional value, but is little used in food. Our objectives were to analyze the chemical composition of the defatted corn germ with pericarp (DCG) and to develop formulations, to evaluate the acceptability and to analyze the chemical composition of cookies with DCG. The proximal composition of DCG and of cookies was determined, and the mineral content and the essential amino acid score (EAE) were analyzed in DCG, according to standard methods of the literature. Cookies with 0% (control), 50% (B50) and 100% (B100) of replacement of oat bran for DCG were formulated. The sensory analysis was performed by using hedonic scale of nine points. The DCG is source of protein (11.7g 100g-1) with optimal amino acid profile (EAE=1.26), and it is rich in dietary fiber (28.9g 100g-1), iron and zinc (5mg 100g-1). All cookies were sensorially accepted (overall acceptance and appearance), and the cookie B50 was more accepted than the B100. The cookies with DCG are source of proteins (12.5g 100g-1) and contain high levels of dietary fiber (10.0g 100g-1). The use of DCG in the formulation of the based-cereal foods increased the nutritional value of these products and can to add value to this byproduct of the corn grain processing.
