Abstract
Employing a luminescence spectrometer the usefulness of light-induced delayed luminescence (DL) for the detection of aflatoxinB1 (AfB1) contamination in whole rice was studied. Rice was artificially contaminated with Aspergillus flavus (7.5×105 conidia/ml) and incubated for 0 - 72 h. The DL spectra of contaminated rice were obtained by a luminescence spectrometer. The correlation between the spectra and contamination levels was established. The DL intensity has a negative correlation with the AfB1 concentration. The results suggested that the DL technique might be useful for the rapid and non-invasive evaluation of AfB1 contamination levels in whole rice.
