UPC2-Q-TOF MS technology was utilized to analyze the TAGs in commercial vegetable oils.
- class="label">•
A total of 30, 29 and 30 different TAGs were identified in the sunflower, corn and soybean oil samples, respectively.
- class="label">•
The sn-position for each TAGs was determined based on high resolution MS and MS fragment information.
