Photochemical Changes of Malonaldehyde by the Presence of Aflatoxins in Model Systems

Abstract
|
|
|
|
On the basis of UV spectral changes and TBA reaction, malonaldehyde (MA) in aqueous solution receives considerable photochemical modification by UV light of short wavelengths around 260 mμ. When aflatoxin is added in the solution, UV light of long wavelengths around 360 mμ induces such changes quite rapidly and although the rate of change is rather slow, it is also true even with ordinary laboratory illumination(fluorescent). The modification is irreversible in nature and the role of aflatoxin in this reaction is identified as a photosensitizer. The mechanism involved in this modification is apparently due to the parallel dimerization of MA molecules, but not by head to tail combination of the molecules.
