Abstract :

The aim of this study was to determine the technological values of three winter wheat cultivars: Bogatka, Bamberka, Muszelka and one spring wheat cultivar Nawra. The total protein content, gluten content, gluten index, Zeleny Index and falling number of grain were evaluated. The grain originated from production farms, from the crop years 2011-2013. Grains were milled using the MLU-202 Bühler laboratory mill. Farinograph and alveograph properties of wheat dough were evaluated. The grain varieties Bamberka and Nawra showed significantly higher protein content, gluten content and Zeleny Index than varieties Bogatka and Muszelka. There was no significant differentiation in falling number between tested wheat varieties. Wheat varieties from 2011 crop were characterised by significantly the highest Zeleny Index and the highest amylolytic activity. Flour obtained from wheat variety Bamberka was characterised by the highest water absorption. Dough obtained from this flour was also estimated the most preferably because it was characterised by the longest development and stability time, the highest quality number, deformation work “W” and elasticity „P”. Wheat flour dough obtained from variety Muszelka was characterised by the least favourable rheological properties. Wheat flour dough from tested varieties from 2012 crop were characterized by the highest extensibility „L”.
