On line monitoring of cereal quality as influenced by fungal growth

Filementous fungi growing in cereals often produce large quantities of fluorescing compounds in laboratory substrates. For this reason it is expected that fungal growth in cereals can eventually be monitored specifically on line by measuring using fluorescence spectra directly on cereal grains. The work has been initiated by a study of the most important penicillia in cereals to see if they can be separated by their excitation fluorescence spectra using multivariate calibration.
