A LC-ESI-Q-TOF Method for Identification and Relative Composition Analysis of Triacylglycerols in Tropical Oil - (2) Palm Oil

User Benefits

- A fast and direct LC-ESI-Q-TOF method was established for identification of TAGs in palm oil and determination of the relative composition of various TAGs with different fatty acids. - A data analysis procedure was set up for unambiguous identification of individual TAG molecules from accurate mass MS and MS/MS spectra using the LabSolutions Insight Explore s/w.

Introduction

The oil palm is a tropical plant originated in the ancient West Africa. In 2018, the world produced 72 million tons of oil palm and 84% of global palm oil production come from Indonesia and Malaysia. Palm oil is used widely as cooking oil, shortenings, margarine etc.. Fatty acid compositions of palm oils have been determined as the key characterization in concerning the health and nutrition. Triacylglycerols (TAGs) are the main form of fatty acids in oils. Analysis of fatty acids in palm oil involves first hydrolysis of TAGs to fatty acid methyl esters, followed by GC-FID analysis. In recent year, direct analysis TAGs by LC-MS/MS and SFC-MS/MS have been used for quick identification of TAGs. In this application news, an LC-ESI-Q-TOF method is described for identification and composition analysis of TAGs in palm oil samples.
