The present work aimed at the development and characterization of flour for human consumption from Achetas domestica (cricket) and Periplaneta americana (cockroach), both species belonging to the order Orthoptera. The crickets were collected in the city of Talara in the Piura department, crickets laboratory-readed and cockroaches collected en the city of Trujillo. For their characterization were performed chemical analysis for determination of protein, fat, ashes, carbohydrates, minerals and energy value. And for the biological analysis were used 8 albino rats for the tests to determine net protein utilization (NPU), digestibility (D) and biological value (Vb). The results of chemical analysis were compared between the flours made from both species, and both were compared with flour made from grasshoppers (Sphenarium purpurascens). The results of biological value were compared with other...
