Saponification Value of Fats and Oils as Determined from ¹H-NMR Data: The Case of Dairy Fats.

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