Changes in baking properties of wheat flour impacted by maltodextrins added


The objective of the research study was to determine the changes occurring in the properties of flour paste, dough, and wheat bread owing to the impact of maltodextrins added. The research material comprised commercial wheat flours (type 550 and 750), low-saccharified (DE = 9.4) and mean-saccharified (DE = 16.8) maltodextrins. The quantity of maltodextrins added was 1, 2, 3 and 4 % of the weighed portion of flour. The quality of the wheat flour was assessed on the basis of total protein content, wet gluten yield and its deliquescence, and sedimentation index. It was also determined the falling number of wheat flour with and without maltodextrins added. Furthermore, the samples were assessed using a farinographic, amylographic, and extensigraphic analysis; a one-phase bread-making laboratory process was performed. The wheat flour types used represented a high baking quality. It was found that owing to the maltodextrins added, the maximum viscosity level of flour pastes tended to decrease. Moreover, they caused the water absorption level of flour to decrease, the time of dough development to extend, and the dough stability to improve; this was a proof that the resistance of dough to mechanical processing increased. The addition of maltodextrins also caused the dough to become more flexible since its extensibility increased and its maximum resistance to stretching decreased. The addition of 1-4 % of maltodextrins to wheat flour, especially of mean-saccharified maltodextrins to wheat flour, its type 550 and its amylolithic activity low, caused the bread volume to increase. The maltodextrins added did not change the yield of bread. However, it was reported that the crumb porosity tended to decrease.
