NIR responds statistically to changes in structure that in a given sample set are correlated with the toxin value. The problem is that in another sample set, from another area or growing season, those correlations have been very inconsistent, and therefore not predictive.

Although aflatoxins are not automatically produced whenever grain becomes moldy, the risk of aflatoxin contamination is greater in damaged, moldy corn tha ...
