According to the food pyramid, cereals have long been one of the main raw materials and the first group in the diet of people. Acrylamide is produced by the Millard reaction when carbohydrate foods are exposed to heat. The amount of acrylamide in products such as cereals, flour products, coffees, potatoes and dried products is significant. Since Taftoon bread is one of the most widely used flour products in the country, in this study, was investigated the effect of asparaginase enzyme and Taftoon bread toasting degree on acrylamide content. For this purpose, the amount of acrylamide was investigated in three cases without toasting, level one toasting and level two toasting, as well as asparaginase enzyme at two concentrations of 250 and 500 ppm in Taftoon bread. Also the effect of these treatments was investigated on the texture and color of bread. According to the results, with increasing of toasting degree, acrylamide content increases too. And increasing of toasting degree leads to darkening of the color bread and increasing shear strength. Use of asparaginase enzyme at a concentration of 500 ppm, at the highest toasting degree was able to reduce the acrylamide content by 86% compared to the control sample. In this study, asparaginase enzyme had no significant effect on texture and color of bread. In the final, samples of bread were made available to the judges for sensory evaluation. The results showed that the asparaginase enzyme did not change the sensory properties of bread despite the decrease in acrylamide content.
