Description
Summary:•Great Northern beans (GNB) are a good source of folate and essential elements.•Extrusion significantly improved dialyzability of essential elements in GNB.•Extrusion drastically reduced Cd dialyzability.•Extrusion resulted in up to 46% reduction in phytate and 24% loss in folate.•Extrusion is promising technique for processing of dry beans. Great Northern beans (GNB) contain appreciable magnesium (Mg), potassium (K), phosphorus (P), and iron (Fe), together with the heat-labile vitamin, folate, and the anti-nutritional compound phytate. Thus, the objective was to increase dialyzability of essential mineral elements while degrading phytate and minimizing destruction of folate through extrusion of GNB. Extrusion resulted in significant (p
