天门冬酰胺酶，又称天冬酰胺酶、门冬酰胺酶等，能特异水解天冬酰胺的酰胺键水解，生成天冬氨酸。可抑制丙烯酰胺的产生，达到减少产品中丙烯酰胺含量的目的。

The Asparaginase Erwinia chrysanthemi, also known as Asparaginase Erwinia Chrysanthemi and Asparaginase Erwinia chrysanthemi, can specifically hydrolyze the amide bonds of L-Asparagine to form L-aspartic Acid. The invention can inhibit the production of acrylamide, thereby reducing the content of acrylamide in the product.
