The contents of free sulphydryl groups (SH), disulphide bonds (SS), and free amino groups (NH₂) were determined in order to estimate the extent of climatic condition influence on gluten quality. The analysis included four bread wheat varieties grown in two production years (2011 and 2012) with different climatic conditions in different locations. According to our previously reported results, the working hypothesis was that enzyme activity for breadmaking purpose was insufficient. The aim of this paper was to study the influence of naturally present enzymes on the bread quality by the addition of previously extracted and freeze-dried albumins to the base flour as an additive. The selection of samples was made on the basis of different combinations of proteolytic and α-amylolytic enzymes activity levels. For samples from 2012 production year, the content of SH groups was significantly higher. Regarding the SS content, the obtained results exhibited the opposite trend. Variations in NH₂ content were dominantly caused by temperature treatment of tested samples. The addition of freeze-dried albumins to bread improved its specific volume in a lesser extent, while bread crumb texture was significantly improved.
