The saponification value of fats and oils is one the most common quality indices, reflecting mean molecular weight constituting triacylglycerols. Proton nuclear magnetic resonance (1H-NMR) spectra display specific resonances for protons from structural patterns triacylglycerols (i.e., glycerol backbone), methylene (-CH2-) groups, double bonds (-CH=CH-) terminal methyl (-CH3) group three fatty acyl chains. Consequently, chemometric equations based on integral values 1H-NMR allow calculation...
