| Abstract : | The aim of this study was to determine the technological value of four winter wheat cultivars (Arkadia, Akteur, Jantarka, Julius) and three spring wheat cultivars (Arabella, Bombona, Brawura) originated from the 2013 crop year. The following parameters of grain were evaluated: test weight, kernel vitreousity, ash content, protein content, gluten content, Zeleny Index and falling number. Grain was milled using the MLU-202 Bühler laboratory mill. The ash content of flour, and the farinograph and alveograph properties of dough were evaluated. The laboratory baking test and assessment of obtained bread were performed. Grain of winter wheat cultivars was characterised by significantly higher vitreousity, lower ash content, higher protein content, gluten content and Zeleney Index value, as well as by favourable-level values of farinograph parameters compared to grain of spring wheat cultivars. In terms of technological value, grain of winter wheat cultivar Arktis was rated the most preferably. Grain of this cultivar was characterised by high value of test weight, low ash content and the highest protein content, gluten content and Zeleny Index, which resulted in favourable evaluation of rheological properties of dough with flour obtained from grain of this wheat cultivar. Bread made from Arktis cultivar was characterised by the highest loaf volume and fine bread crumb. |
