M. aOptimization of nutrient retention in whole flours extruded from cowpea biofortified grain.h[electronic resource] c2021 a13 p. aWhole flour of cowpea grains of the cultivar BRS Tumucumaque biofortified in iron and zinc were processed in a co-rotating twin-screw extruder Clextral HT 25. A central rotational composite design 23, combining temperature (from 86.4 to 153.6 °C), screw rotation speed (from 163.6 to 836.4 rpm) and moisture content (from 16.6% to 23.4%), was used to assess the effects on flour constituents. The three variables significantly affected (p < 0.05) the levels of protein and copper in the extrudates. aComposição Química aExtrusão aVigna Unguiculata aElementos minerais aFarinha instantânea aMetodologia de superfície de resposta1 aSAMPAIO, J.
