Bread making potential of Triticum aestivum and Triticum spelta species

The aim of this study was to assess the effect of two winter wheat species: Triticum aestivum ssp. vulgare, and Triticum spelta, cultivated in different percentage of cereals in crop rotation, on their bread making potential. The analyzed grain samples were obtained from a field experiment conducted during three years 2014-2016 at the Experimental Station in Osiny (51°35’, 21°55’), Institute of Soil Science and Plant Cultivation, State Research Institute, Puławy, Poland. The experiment was established following different percentages of shared cereals in crop rotation (SCCR): 50, 75 and 100%. Wheat cultivation was performed in accordance with good agricultural practice standards. Protein content, gluten content, Zeleny sedimentation index and alveograph properties were determined. Wheat species strongly influenced bread potential. The Triticum aestivum compared to Triticum spelta was characterized by significantly higher gluten quality and Zeleny sedimentation index as well as better alveograph properties. Common wheat showed the highest baking value (W). Spelt wheat was characterized by the lowest tenacity (P) and the highest extensibility (L). Moreover, the percentage of cereals in crop rotation had an effect on grain and dough quality parameters. Cultivation of wheat in 100% share of cereals resulted in the lowest grain and dough quality
