The objective of the study was to determine effects of wholegrain barley flour on the quality of wheatbarley bread manufactured using different dough making methods. Additionally, it was assessed the effect of vital gluten or/and soy lecithin additives on the quality of bread containing up to 40% of the wholegrain barley flour. The study proved that the best quality had breads containing 20% to 30% of the wholegrain barley flour, and produced using a method with an initial phase of soaking barley flour. The comparably good quality had breads containing 20% of barley flour and made using one- and three-phase methods. When wholegrain barley flour was added, and its amount replaced 40% of the wheat four in the breads, the results were: a reduced bread volume, and a deteriorated crumb structure of the breads. Furthermore, it was stated that vital gluten or/and soy lecithin additives, added to a bread dough containing 20% to 40% of whole barley flour, and made using a single-phase method, improved the quality of both the dough and the bread features. A complex additive (7% of vital gluten and 0.5% of soy lecithin) was found and assessed as the most effective agent if applied in the production of breads with up to 40% of wholegrain barley flour.
