“…By diluting Aspergillus flavus aflatoxin (Sigma‐Aldrich, 3050 Spruce St., St. Louis, Mo., U.S.A.) with methanol, which was also used to kill any residual mold spores in AFB 1 , and according to the average kernel weight 0.33 g, 4 concentrations of stock solutions, that is 10, 20, 100, and 500 ppb, were prepared. For the detailed procedure please refer to Wang and others (). Once the solutions were prepared, the kernels were divided into 5 groups.…”

“…Before imaging, kernels from a given group (30 at a time) were placed on a Teflon® sample holder containing 30 shallow, elliptically shaped wells arranged in 6 rows × 5 columns (Figure A). As a safety measure, the Teflon holder was placed inside of a special transparent sealed box before imaging (Wang and others ).…”

“…Near-infrared hyperspectral imaging technique to detect different quality parameters, insect infestation, and fungal infection associated with different stored grains and oil seeds were reported by , and Teena et al (2013). NIR hyperspectral imaging technique in the wavelength range between 1000 and 2500 nm, was utilized to detect aflatoxin B1 in single maize kernels with classification accuracy between 80 and 96.1% (Wang et al, 2015a), Aflatoxin B1 concentration of as low as 10 ppb on maize kernel surfaces was identified using NIR hyperspectral imaging in the wavelength range between 1000 and 2500 nm with a classification accuracy of 88% . Wang et al (2015b) identified wavelengths 1729 and 2344 nm corresponding to the presence of aflatoxin B1 in maize kernels.…”
