Acrylamide is an undesirable carcinogenic component of thermally processed foods being formed from reducing saccharides and asparagine. In this work, the effect of ammonium and sodium raising agents themselves or in their combination with L-asparaginase enzyme catalyzing the conversion of asparagine into aspartic acid resulting in the reduction of acrylamide in gingerbreads was studied. Also, the influence of selected inorganic salts on the content of acrylamide in a model matrix simulating a composition of cereal products was observed. Simultaneously, the impact of these salts on activity of L-asparaginase was examined to find optimal conditions for its application in cereal technology. Based on experiments it was found, that addition of L-asparaginase reduces acrylamide content by 40 % while inorganic salts addition decreases acrylamide content in the range of 30 - 99 % when the most effective compounds were NH4Cl and CaCl2.
