Abstract

© 2022 Elsevier LtdEffect of asparaginase was tested in different biscuit and cracker doughs, and wafer batter by changing processing conditions such as enzyme dosage, dough resting time and temperature, mixing speed and time, and mixing procedure of the recipe components. Acrylamide reductions achieved were 96, 80, 54% in rotary cut biscuits, crackers and wire cut cookies, respectively due to high water activity of their dough. Asparaginase did not affect surface color or spread ratio. There was a positive correlation between asparagine content and acrylamide formation except for rotary molded biscuit doughs. No significant decrease was found in rotary molded biscuits because of low water (water activity of 0.70) and high fat content. This indicated that water activity of dough is an important factor for the effectiveness of asparaginase treatment. The results suggested that water activity value exceeding 0.75 is needed in the dough to effectively reduce asparagine, so acrylamide in bakery products.
