Food Grade Asparaginase is an enzyme preparation developed for high-temperature processing of starch-rich foods. It is suitable for baking, frying, roasting, and other heat-intensive food manufacturing processes where control of asparagine levels is required.
During prolonged high-temperature processing of starch-rich raw materials, such as frying or baking, sugars can react with asparagine through the Maillard reaction. While this reaction contributes to desirable color
and flavor, it may also lead to the formation of undesired reaction products. Reducing the asparagine content before high-heat treatment is therefore an important step in many modern food formulations.
Mechanism of Action: Asparaginase converts asparagine into aspartic acid. Aspartic acid does not participate in the same reaction pathway during high-temperature processing. By reducing the precursor asparagine
content at the source, this enzyme helps lower formation risk while maintaining the product’s appearance, flavor, and overall sensory quality.
In starch-rich food raw materials, during prolonged high-temperature processing such as frying or baking, sugars react with asparagine through the Maillard reaction. This reaction gives starch-based foods their characteristic color and flavor, but at the same time it can also produce a potential harmful substance — acrylamide. Acrylamide is neurotoxic, transmissible, and potentially carcinogenic, so controlling the level of acrylamide in food is extremely important.
Asparaginase can reduce the content of asparagine in raw materials. Specifically, asparaginase converts the precursor substance that forms acrylamide — asparagine — into aspartic acid. Aspartic acid does not generate acrylamide during subsequent Maillard reactions. Therefore, the use of asparaginase can control the formation of acrylamide in foods at the source. In addition, while reducing acrylamide levels, asparaginase does not affect the product’s appearance, taste, or flavor.
