Celiac disease is attributable to autoimmune diseases, where treatment is based on absolute respect for gluten-free diet. As the gluten used widely in all areas of food production, strict adherence to a gluten-free diet really can be difficult for people with celiac disease. Products suitable also for those suffering from the disease are usually expensive. Finally, patients that undergo exclusively on a gluten-free diet are robbing the important nutritional components. Therefore, interest in this type of products innovation enhance as to the nutritional, technological, as well as organoleptic properties. The aim of this final thesis was to draw up literature review of the celiac disease and gluten allergen, or his particular part of gliadin. In the experimental part, attention was focused on the first hydrolytic cleavage of starch, the substrate was sterilized wheat flour and water, where is incorporated spiral just gluten. The best ability of degrading the starch grains, the combination of enzymes and MT3K and GLUAMK concentration of 0, 1% over 4 hours of action, as indicated by a reduction in the starch content of the original amount of 72,65 % at a concentration of 29,00 %. The next item of work distribution used different proteases, to reduce the amount of gliadin to below 20 ppm per kilogram of final product. Low levels investigated allergen (10,79 ppm/kg) recorded by the enzyme combination exoprotease Flavourzyme (0,1 %) and endoprotease Neutral Protease (0,1 %) at 7 hours hydrolytic action. The conclusion of the thesis was prepared several alternatives gluten-free breads and through sensory evaluation assessed the characteristics of color, aroma and taste to predict the location of the products on the commercial market.
