Sammanfattning
An agricultural growing experiment cultivating 10 cultivars at five localities produced whole wheat flour samples that were analysed by Fourier transform near infrared (FT-NIR) spectroscopy. This produced a three-way data array: locality x cultivar x wavelength. By taking smoothing first derivatives and removing a noisy part of the spectra meaningful PARAFAC (PARAllel FACtor analysis) models could be produced. Two factors could be interpreted spectroscopically, showing that cultivar properties are related in a not so trivial way to average wheat hardness values and that locality variations are straightforwardly related to average protein content.
