摘要

Aflatoxins are a family of carcinogenic toxins produced by Aspergillus tlavus and Aspergillus parasiticus fungi and occur on agricultural crops such as maize or corn, peanuts, cottonseed, and tree nuts. Even at low concentrations (< 20 ppb), it affects the liver, kidneys, heart, respiratory, nervous, endocrine systems and growth in infants and children. The economic impact of aflatoxin-associated is estimated to be on the order $47M of losses per year in food crops and $225 million per year in feed crops. Current methods for detection include chromatographic methods, spectroscopy and immunochemistry. Although very sensitive, these are largely cumbersome, require extensive sample preparation, skilled operators and in the case of chromatography, very expensive equipment. Hyperspectral imaging offers a sensitive, convenient, compact, reliable, relatively economical and simple to operate solution requiring little or no sample preparation that can be used in the laboratory or the field.
