Coeliac disease is the intolerance of prolamine from wheat, rye, oat and barley. The special food for people suffering from coeliac disease contains too low quantities of both the necessary nutrients and dietary fiber. For the purpose of the investigations as described in this paper, fiber preparations of apples, tomatoes, and Psyllium (Plantago ovata) were added to a gluten-free bread to enrich it by fiber; the portions of additives equaled 5%, 7.5%, and 10%. It was stated that the dietary fiber content in bread loaves was 190% to 450% higher compared with the standard ‘control’ bread. A preparation made of apples (VITACEL AF) and a fine granulated tomato preparation (VITACEL TF 200) were determined the factors influencing this parameter and, generally, bread quality in the most favorable way. Thanks to all fiber containing additives, the bread crumbs investigated became less hard and remained less hard during a 4-day period of storage. However, the effect of these additives on other parameters and qualities of texture profiles varied, moreover, this effect was not always favorable.
