Lignin is the main determinant of total dietary fiber differences between date fruit (Phoenix dactylifera L.) varieties

Date fruits (Phoenix dactylifera) of ten varieties, collected in the United Arab Emirates, were studied to determine their dietary fiber content and composition. Fourier transform infrared (FTIR) spectroscopy indicated that the dietary fiber components in all the date fruit varieties was similar. Th...
