Comparing rheological properties of dough and quality of bread made of spelt and common wheat flours


The objective of the study was to assess the technological value of spelt strains compared to common wheat. Six strains of spelt and one cultivar of common wheat being a control sample were analyzed. The grain was ground in the ‘Brabender Quadrumat Senior’ laboratory mill. The assessment of the technological value of flour included: flour yield, total protein content, wet gluten yield, gluten index, sedimentation value, falling number and total ash content. A Chopin alveograph and a Brabender farinograph were applied to determine rheological properties of dough. The dough was made using a single-phase wheat method. The bread was baked in an electrical oven manufactured by a Sveba Dahlen company. The baked bread was weighed for the purpose of calculating the total baking loss and baking yield. Furthermore, the volumes of bread loaves were measured and the bread quality was rated using a point scoring system. It was found that some spelt flours were characterized by a higher total protein content and wet gluten yield compared to common wheat flour. The α – amylase activity level in spelt flours ranged from the average to low value. The doughs obtained using spelt flours were characterized by a longer development and stability time; thus, they should be mixed for a longer time than the dough of common wheat flour. Additionally, they were less elastic and more extensible compared to doughs of common wheat flour. There are also some spelt flours (STH 8, STH 12, STH 13, and STH 24 strains), which, when used to bake bread, produce bread of the quality that does not differ from the quality of bread made of common wheat flour.
