Abstract

The aim of this research was to elaborate a high-protein extruded snack from quinoa (Chenopodium quinoa Willd.), tarwi (Lupinus mutabilis Sweet) and sweet potato starch (Ipomoea batatas L.). For its formulation, the mixture design method was applied using Design Expert® 7.0 software. Quinoa, tarwi and sweet potato starch were the independent variables and the dependent variables were the protein content, expansion index, bulk density and hardness of the extrudates. The optimal formulation was determined by applying the test of desirability based on adjusted regression models, this formulation was obtained by maximizing the protein content and expansion index, and minimizing the hardness and bulk density of the extrudates. The optimal formul...
