Evaluating the potential for enzymatic acrylamide mitigation in a range of food products using an asparaginase from Aspergillus oryzae.

Asparaginase, an enzyme that hydrolyzes asparagine to aspartic acid, presents a potentially very effective means for reducing acrylamide formation in foods via removal of the precursor, asparagine, from the primary ingredients. An extracellular asparaginase amenable to industrial production was cloned and expressed in Aspergillus oryzae . This asparaginase was tested in a range of food products, including semisweet biscuits, ginger biscuits, crisp bread, French fries, and sliced potato chips.
