Food additives such as enzymes and hydrocolloids are widely used to improve bakery products. By setting a goal to increase crop volume and increase flour strength, in this study, along with a control sample, Sodium alginate and alpha-amylase enzyme during 8 samples (in different amounts, respectively, alpha-amylase and sodium alginate 75-0, 150-0, 0-150, 0-300, 75-150, 75-300, 150 150, 300-150 mg) were added to the bread dough and then rheological properties were investigated by farinograph and extensograph devices. The results showed that among all treatments, treatment 5 (containing 300 mg of sodium alginate) was the best treatment in the studied factors such as development time, consistency, water absorption, stability, degree of softening, farinograph quality number and tensile strength. Therefore, it is recommended to use 300 mg of sodium alginate hydrocolloid to increase the volume and strength of the flour
Keywords: alpha-amylase, sodium alginate, bread, extensograph, farinograph
