Lipid oxidation of fat blends modified by monoacylglycerol

Model dispersions of fat blends (FBs) with monoacylglycerols (MAG) of saturated fatty acids with different lengths of the acyl chain (MAG10-MAG18) and 1-octadecenoylglycerol, and without MAG (as blank) were prepared. We find out the influence of the addition of monoacylglycerol on oxidation of the f...

Zusammenfassung:	Model dispersions of fat blends (FBs) with monoacylglycerols (MAG) of saturated fatty acids with different lengths of the acyl chain (MAG10-MAG18) and 1-octadecenoylglycerol, and without MAG (as blank) were prepared. We find out the influence of the addition of monoacylglycerol on oxidation of the fat dispersion. Trihexadecanoylglycerol (tripalmitoylglycerol - TAG48) was used as the dispersive phase, soybean oil was used as the dispersive medium. Primary (conjugated diens) and volatile secondary (by SPME in connection with GC-MS) lipid oxidation products and oil stability index (OSI) were measured during autoxidation of the fat blends in storage conditions. MAGs with a shorter (or the same) acyl chain length (MAG10-MAG16) than the acyl chain length of the structured fat (TAG48) arrange tightly on the interface oil/crystals of structured fat, thus prevent lipid oxidation.
