DETECTION OF FORMALDEHYDE

摘要

The present invention discloses an electrochemical method to determine the presence of formaldehyde in food samples, for example fish and other seafood products by way of an enzymatic-based sensor. The method includes contacting the sample with an amperometric sensor, which comprises an electrode coated with an immobilized enzyme and measuring the current changes as the output signal at a constant voltage, which indicates the presence of formaldehyde in the sample.
