Abstract
Volatiles in soybean oil samples measured by methods based on Dupuy's direct gas chromatographic technique have been shown to correlate well with the amount of light abuse the oil has received. Another approach to measuring these flavor-important volatiles is capillary headspace gas chromatography. This approach to measuring light-induced volatiles appears to offer several advantages. The benefits of extraordinary analytical simplicity, good precision and accuracy, and high sensitivity are inherent to the headspace technique; the additional benefits of superior peak resolution and shortened analysis time can be attributed to the use of capillary columns. After carefully selecting appropriate experimental parameters, the method was demonstrated to be a good indicator of the oil's history with respect to abuse by light and contact with copper.This publication has 0 references indexed in Scilit:
