Resumo
The germ fraction with maize pericarp (GMP), obtained from the degermination of this cereal, presents a high nutrient density, however, it is underused as food. Therefore, the objective of this study was to develop cookies enriched with GMP, in order to evaluate their acceptability and determine their centesimal composition. The GMP fraction was added to the formulations, in the proportion of 40% and 50%, in replacement of wheat
flour and cassava starch. Centesimal composition analyses were performed for both the GMP fraction and cookies. All cookies were accepted, in relation to global acceptance, however, only the cookie with 40% replacement of wheat flour and cassava starch by GMP was accepted, concerning appearance. The GMP fraction showed high levels of lipids (18%) and total dietary fiber (29%), and considerable protein content (12%). Significant differences were observed in the protein content of the cookie with 50% replacement of wheat flour and cassava starch by GMP (7.76 g 100g-1), in relation to the control and the cookie with 40% replacement (6.76 g 100g-1 and 6.88 g 100g-1, respectively). The GMP fraction increased the dietary fiber content, did not change the lipids concentration, and reduced the energy value of cookies. The use of germ fraction with maize pericarp in food products allows the increase of their dietary fiber content and the decrease of their energy value.
