Method for reducing acrylamide in corn-based foods, corn-based foods having reduced levels of acrylamide, and article of commerce
A method for the reduction of acrylamide in corn-based food products, corn-based food products having reduced levels of acrylamide, and an article of commerce. In one aspect, the method comprises reducing the level of asparagine in a corn-based food material before final heating (e.g., cooking). In another aspect, the method comprises adding to a corn-based food material an enzyme capable of hydrolyzing the amide group of free asparagine. In yet another aspect, an article of commerce communicates to the consumer that a corn-based food product has reduced or low levels of acrylamide or asparagine.
1. A method for removing asparagine or converting asparagine to a different substance by hydrolyzing the amide group of the asparagine to form aspartic acid in a corn-based food material comprising adding asparaginase enzyme to the food material before heating.
2. The method of claim 1 , wherein at least about 10% of the asparagine is converted to a different substance or removed.
3. A method for removing asparagine or converting asparagine to a different substance by hydrolyzing the amide group of the asparagine to form aspartic acid in a corn-based food material, comprising:
(1) adding asparaginase enzyme to the corn-based food material, wherein said corn based food material comprises asparagine;
(2) optionally mixing the enzyme with the corn based food material;
(3) allowing a sufficient time for the enzyme to react with the asparagine; and
(4) optionally deactivating or optionally removing the enzyme.
4. A method for reducing the level of acrylamide formed in heated corn-based food products, comprising:
(1) adding asparaginase to a corn-based food material, wherein said corn-based food material comprises asparagine;
(2) optionally mixing the enzyme with the corn-based food material;
(3) allowing a sufficient time for the enzyme to react with the asparagine whereby at least a portion of the asparagine is removed or is converted to a different substance by hydrolyzing the amide group of the asparagine to form aspartic acid;
(4) optionally deactivating or optionally removing the enzyme; and
(5) heating the corn-based food material to form the heated corn-based food product.
5. A corn-based food material prepared according to the method of claim 1 , wherein at least about 10% of the asparagine is converted to a different substance or is removed.
6. A corn-based food material prepared according to the method of claim 1 , wherein at least about 30% of the asparagine is converted to a different substance or is removed.
7. A corn-based food material prepared according to the method of claim 1 , wherein at least about 50% of the asparagine is converted to a different substance or is removed.
8. A corn-based food material prepared according to the method of claim 1 , wherein at least about 70% of the asparagine is converted to a different substance or is removed.
9. A corn-based food material prepared according to the method of claim 8 , wherein at least about 90% of the asparagine is converted to a different substance or is removed.
