Conclusions

  • Both (700-1050nm) and (900-1700nm) NIR spectroscopic techniques showed good potential
  • Neuralnetwork-based classifier showed higher classification accuracies than statistical classifiers
  • Spectral information in 900-1700 nm with NN classifier showed highest accuracies (100%) for classifying good, moldy, and rancid kernels as compared to these in 700-1050 nm

Other contributions

  • Establish fatty acid profiles
  • Oil content prediction
