Triacylglycerol Composition of Butterfat Fractions Determines Its Gastrointestinal Fate and Postprandial Effects: Lipidomic Analysis of Tri-, Di-, and Mono-acylglycerols and Free Fatty Acids.

The lipolytic behaviors and postprandial effects of butterfat and its fractions (30L and 30S) procured by dry fractionation at 30 °C were investigated using digestion. A total of 142 triacylglycerols (TAGs), 64 diacylglycerols (DAGs), 14 monoacylglycerols (MAGs), and 7 free fatty acids (FFAs) in the butterfat fractions and their hydrolysates were identified by combining high-performance liquid chromatography coupled with electrospray ionization-tandem quadrupole time-of-flight mass spectrometry with solid-phase extraction. The first-step hydrolysis from TAGs to DAGs occurred slower in the high-melting-temperature solid fat (30S) fraction, which is rich in long-chain FAs compared to that of the low-melting-temperature liquid oil (30L) fraction, which is rich in short-chain unsaturated FAs (the hydrolysis rates were 39.
