Characterization of Triacylglycerides (TAGs) in Vegetable Oils using MALDI LTQ Orbitrap XL Instrumentation
Description
The world’s population growth has led to increase in consumption of vegetable oils by 4.5% in 2011. By 2020, the annual production is expected to expand by 23%. Import rates for vegetable oils into the EU are predicted to rise significantly. Cases of economic adulteration of vegetable oils with non-authentic and less expensive oil adjuncts occur frequently. We describe a method to uncover structures of specific TAGs and TAG distribution patterns among various vegetable oils exploiting full MS and CID-based MSn experiments using the Thermo Scientific MALDI LTQ Orbitrap XL.| Market: | Food and Beverage |
