Abstract
The lipid fraction of wheat of different species (TA = Triticum aestivum and TD = Triticum durum), varieties, origin and year of production was extract and analysed. The gas chromatographic analysis was performed by using FID and mass spectrometry as a highly sensitivity detector, with very low noise. The chromatograms showed the presence of an average of 60 peaks. Most of the compounds (not less than 92%) were identified and determined.. Fatty acids with carbon atoms even numbers from C-12 to C-30, C-15 and C-17 were found. The major components of the fat were saturated and unsaturated C-16 and C-18. Squalene and a consistent sterol fraction (about 2%) were present, as well. Differences among varieties, species and origin were found and discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
