dc.description.abstract | Monofloral sunflower honey was harvested from the enchanting vast sunflower fields in the
vicinity of Cestereg (Central Banat) serving as a rich source of floral nectar collected by honey
bees. The aim of the study was to detect predominant sugars such as glucose, fructose, sucrose
and maltose in sunflower honeyof known origin using Raman spectroscopy. The Raman spectra
were recorded with XploRA Raman spectrometer from Horiba JobinYvon, on laser at a wave
length of 785 nm. Several vibrational bands at 415, 514, 564, 622, 703, 769, 815 cm-1
, followed
by 856, 914, 964, 1021, 1067 and 1123, 1260, 1360 and 1455 cm-1
could be identified as
fingerprints of the major sugar constituents of honey, fructose and glucose, whereas sucrose and
maltose bands have been suppressed. The highest intensity bandat 415 and its shoulder at 446 cm1
are attributed to the C–C–O vibration of α- and β- glucose, respectively. The higher intensity
signals at 514cm-1
could be assigned to the skeletal vibration of glucose and 622 cm-1
to the ring
deformation of fructose, due to its highest content in the honey sample. Finally, the bands at
1123, 1260, 1360 and 1455 cm-1 were related to the C-O-H deformation of the glucose and
sucrose, C-O-C cyclic alkyl ethers of the fructose, CH and OH bending modes of the glucose and
sucrose and the symmetric deformation mode of CH2 in fructose, respectively. This study
confirmed that Raman spectroscopy can be applied for rapid determination of sugar contents of
commercial honey. | sr |
