OPTICAL FLUORESCENCE ENHANCERS FOR TRACE DETECTION OF Ml AFLATOXIN

摘要

Aflatoxin M1 (AFM1) is classified as hazardous food contaminant occurring in several dairy products. A portable and easy-to-handle fluorometer for the AFM1 rapid detection is presented. The system is intended to be used as an "early warning system" so as to quickly single out risk or alarm situations. The addition of cyclodextrin (CD) to the AFM1 solution is investigated, as a tool to enhance the fluorescence signal, in order to increase the system sensitivity. Preliminary results are reported which show that succinyl-β-CD can be successfully used to improve the overall sensitivity.
