ABSTRACT A high-speed dual-wavelength sorter was tested for removing corn contaminated in the field with aflatoxin and fumonisin. To achieve accurate sorting, single kernel reflectance spectra (500–1,700 nm) were analyzed to select the optimal pair of optical filters to detect mycotoxin-contaminated corn during high-speed sorting. A routine, based on discriminant analysis, was developed to select the two absorbance bands in the spectra that would give the greatest classification accuracy. In a…

Development of narrow-band fluorescence index for the detection of aflatoxin contaminated corn

Aflatoxin is produced by the fungus Aspergillus flavus when the fungus invades developing corn kernels. Because of its potent toxicity, the levels of aflatoxin are regulated by the Food and Drug

Detection and removal of single mycotoxin contaminated maize grains following harvest.

Near-infrared reflectance spectra were analyzed to select the pair of absorbance bands giving the lowest classification error rate for removing whole yellow maize grains contaminated with aflatoxin and fumonisin from a commercial high speed sorter.

Automatic detection of aflatoxin contaminated corn kernels using dual-band imagery

Aflatoxin is a mycotoxin predominantly produced by Aspergillus flavus and Aspergillus parasitiucus fungi that grow naturally in corn, peanuts and in a wide variety of other grain products. Corn, like

Industrial-Scale Cleaning Solutions for the Reduction of Fusarium Toxins in Maize

Grain cleaning is the most effective non-destructive post-harvest mitigation strategy to reduce high levels of mycotoxins on account of the removal of mold-infected grains and grain fractions with

Development of high speed dual-camera system for batch screening of aflatoxin contamination of corn using multispectral fluorescence imaging

Aflatoxins are fungal toxins produced by Aspergillus flavus. Food and feed crops get contaminated with carcinogenic aflatoxins, which often results in economic losses as well as serious health

High-Speed Optical Sorting of Soft Wheat for Reduction of Deoxynivalenol.

A study was undertaken to examine the efficiency of high-speed, optical sorting of intact wheat (Triticum aestivum) kernels for reduction of DON concentration and found that multiple sorting was effective in producing wheat whose DON concentration was between 16 and 69% of its original, unsorted value.

Aflatoxin Reduction in Maize by Industrial-Scale Cleaning Solutions

This study shows that a cleaning line combining both mechanical and optical sorting technologies provides an efficient solution for reducing aflatoxin contamination in maize.



Influence of Aspergillus flavus Strains on Aflatoxin and Bright Greenish Yellow Fluorescence of Corn Kernels.

Results indicated substantial variation among A. flavus genotypes in their ability to produce aflatoxin in the germ and endosperm of infected BGYF kernels.


Transmittance spectra (500 to 950 nm) and reflectance spectra (550 to 1700 nm) were analyzed to determine if they could be used to distinguish aflatoxin contamination in single whole corn kernels.

Cleaning trials for corn containing aflatoxin

Physical separation methods were generally ineffective for lowering the aflatoxin content of naturally contaminated corn used in the experimental work. The corn lots tested differed in aflatoxin

Reflectance and Transmittance Spectroscopy Applied to Detecting Fumonisin in Single Corn Kernels Infected with Fusarium verticillioides

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
