ABSTRACT Reflectance and transmittance visible and near-infrared spectroscopy were used to detect fumonisin in single corn kernels infected with Fusarium verticillioides. Kernels with >100 ppm and <10 ppm could be classed accurately as fumonisin positive or negative, respectively. Classification results were generally better for oriented kernels than for kernels that were randomly placed in the spectrometer viewing area. Generally, models based on reflectance spectra have higher correct…

Detection of aflatoxin and surface mould contaminated figs by using Fourier transform near-infrared reflectance spectroscopy.

Combined with pattern classification methods, the NIR spectroscopy can be used to detect aflatoxin contaminated figs non-invasively and a positive correlation between surface mould and a Flatoxin contamination leads to a promising alternative indicator for the detection of a flatoxin-contaminated figs.

CLASSIFICATION OF SCAB– AND OTHER MOLD–DAMAGED WHEAT KERNELS BY NEAR–INFRARED REFLECTANCE SPECTROSCOPY

Scab (Fusarium head blight) is a disease that causes wheat kernels to be shriveled, underweight, and difficult to mill. Scab is also a health concern because of the possible concomitant production of

Methods and issues regarding detection of deoxynivalenol, Fusarium-damaged kernels, and Fusarium spp. in commercial grain in Canada

Among the detection methods reviewed for the grain trade, image analysis and near infrared spectoscopy are the most attractive because they are nondestructive, simple, and have multiple applications; however, the adoption of these methods may be restricted by capital cost and their limit of detection.

Fumonisin Production in Corn by Toxigenic Strains of Fusarium moniliforme and Fusarium proliferatum.

Both fungi are ear rot pathogens of corn, thus, mycotoxin production occurs under field conditions, although it also may occur in storage, and the range of concentrations reported is 0.3 to 330 μg/g of corn-based product.

The results suggested that although the immunoassay could be used for screening of fumonisin in food samples, higher estimates were attained by ELISA than by the other two methods particularly in the more contaminated samples.
