Analysis of the volatile components of heated esterified propoxylated glycerols
Static headspace (HS) and capillary gas chromatography/infrared spectroscopy-mass spectrometry (GC/IR-MS) were used to collect, separate, identify and quantitate the oxidative and thermal decomposition products in heated triolein, trilinolein and esterified propoxylated glycerols (EPGs), EPG-08 oleate and EPG-08 linoleate. Approximately 4 L of each oil sample (triolein, trilinolein, EPG-08 oleate and EPG-08 linoleate) with and without added antioxidants were separately heated in a deep fat fryer at $\rm 190\sp\circ C$ for 12 h each day until each contained $\ge$20% polymeric material.
