- Abstract:
- The purpose of this paper was to compare the composition (weight % of total identified FA) in saturated (SFA), monounsaturated (MUFA) and polyunsaturated (PUFA) fatty acids from 3 food matrices (sunflower oil, palm oil and lard) by 2 different techniques, GC-MS and NMR.
FAMEs analysis from food samples was performed using a gas chromatograph coupled with a Triple quadrupole mass spectrometer.
NMR spectra were recorded on a Bruker Advance 400 MHz spectrometer, operating at 9.4 Tesla corresponding to the resonance frequency of 400.13 MHz for the 1H nucleus.
The composition in fatty acids determined by these two techniques was compared and the difference between the mean values determined by GC-MS and NMR was not more than ± 15% for sunflower oil, and lard, and ± 6% for palm oil. - Keywords:
