Correlations between chemical and certain rheological quality parameters of wheat flour and bread

Abstract

The aim of this research was to determine existence of the correlation between chemical and certain rheological quality parameters of different wheat flour samples and quality of bread produced from them. Three samples of wheat flour type 500, which were produced as experimental samples in industrial conditions, were analyzed. The analysis of chemical composition (content of water, ash, ash on dry matter, fat, protein, starch) and farinograph parameters (farinograph water absorption, dough development time, stability of dough, softening degree of dough, quality number, quality group) of experimental samples of wheat flour has been conducted. These analyzed flour samples were used for bread production. Also, quality parameters of three produced bread samples were analyzed (volume of bread, mass of bread, overall sensory quality of bread). After that, the existence of the correlation between analyzed parameters has been examined and found as very important correlation between farinograph water absorption (FWA) and parameters of chemical composition: water content (p˂0.05), fat content (p˂0.05), protein content (p˂0.05) and starch content (p˂0.05). Also, a significant impact and positive correlation between the protein content and farinograph water absorption (FWA) on bread volume (p˂0.05) has been found.
