Technical Abstract: It is demonstrated here, that in the case of normal and modified seed oils for which no commercial standards were available, reversed phase high performance liquid chromatography coupled to a mass spectrometer via an atmospheric pressure chemical ionization source could provide excellent qualitative identification of molecular species and differentiation, by mass, of completely overlapped species of triglycerides. Further, excellent quantification of the triglycerides was demonstrated. The ability to produce a good estimate of a product's triacylglycerol composition will be central to gaining a better understanding between triacylglycerol form and function in the development of food formulation products.
