The changes in physical, chemical and sensory properties of common bean (CB) and chickpea (CP) bulgur prepared with different cooking (atmospheric, pressure and microwave) and drying (oven at 60, 70 and 80C; microwave at 350 and 700 W) processes were investigated. Neither the cooking methods nor the drying methods significantly affected the ash and protein contents of CB and CP bulgur. Pressure cooking gave lower phytate phosphorus and higher bulgur yield and volume increase values when compared to the other cooking methods. Average bulgur yields were found as 82% for CB and 84% for CP. Cooking processes decreased the phytic acid content of the bulgurs between 25.2 and 39.5% according to raw legume. Ca, K, Mg, P, Zn, Cu and Fe contents of the bulgurs decreased in variable degrees (8.69–28.5%) when compared to raw materials. Pressure cooked and oven (80C) dried bulgur samples in the case of bulgur pilaf were appreciated by the panelists in terms of overall acceptability.PRACTICAL APPLICATIONS Bulgur is a valuable cereal product with its high nutritional value and long shelf life. In this research, bulgur process was applied successfully on common bean and chickpea, and new legume‐based bulgur products improved. The bulgur yield (BY) of the legumes was above 80%. Pressure cooking increased the nutritional, sensory and technological quality of the legume bulgurs.
