Background:
Pulsed light (PL) is a new potential technology to degrade aflatoxin. The objective of this study was to investigate the degradation characters of aflatoxin B1 (AFB1 ) and B2 (AFB2 ) treated under PL irradiation. A kinetic degradation study of AFB1 and AFB2 in solid medium was performed under PL irradiation at different initial concentrations of AFB1 (229.9, 30.7 and 17.8 μg kg-1 ) and AFB2 (248.2, 32.2 and 19.5 μg kg-1 ) and irradiation intensities (2.86, 1.60 and 0.93 W cm-2 ) of PL. A second-order reaction model was applied to describe degradation of AFB1 and AFB2 .
Results:
The results showed that the degradation of AFB1 and AFB2 followed the second-order reaction kinetic model well (R2 > 0.97). The degradation rate was proportional to the intensities of PL irradiation and the initial concentrations of aflatoxins.
Conclusion:
It is concluded that the degradation of AFB1 and AFB2 with the use of PL could be accurately described using the second-order reaction kinetic model. © 2018 Society of Chemical Industry.
