Making biosensor - L- Asparaginase has also been used for making a diagnostic biosensor as the amount of ammonia
produced by the action of the enzyme directly correlates to the level of L- asparagine in a patient’s blood
Role in food processing - Moreover it is also used in food processing. Recent advances in food technology have
demonstrated that fried and baked food (particularly fried potato) contains a significant amount of acrylamide (a
carcinogenic toxicant)[10]; [11], formed by the reaction of asparagine with reducing sugars [12]. A pretreatment of
potato slices and bread dough with asparaginase before frying or baking prevents acrylamide formation [13] [14]. In
this regard, asparaginases from Aspergillus oryzae and A. niger are used in baking industries [15]. These enzymes work
optimally at 40-60ºC and pH 6.0-7.0. Since baking temperatures often go up to 120ºC, it is desirable to have enzymes
that are stable and active over a wide range of temperature and pH. Therefore, L-asparaginases from various sources
(bacterial, fungal, plant, and animal) have been investigated. So, L-asparaginases have both therapeutic and industrial
applications.
