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.
