A diode-array near-infrared spectrometer was used to rapidly analyze
single corn kernels for attributes such as BGY fluorescence, aflatoxin, avidin, fusarium, and fumonisin. NIR
spectra were well correlated to BGY fluorescence. Transgenic corn with high levels of avidin could be
identified based on NIR absorption characteristics. Data from tests correlating NIR spectra to aflatoxin,
fumonisin, and fusarium are currently being analyzed. These tests will show the potential for NIRS to
measure important attributes of corn. This information can then potentially be used to sort individual corn
kernels based on intrinsic quality characteristics.
