Olfactory Analysis of Palm Olein and Cottonseed Oils and their Various Mixtures

The objective of this research is to investigate the olfactory characteristics of the two selected oils and their various bends using a metal oxide sensor-based instrument (electronic-nose) for headspace analysis. The instrument was also employed to identify the percentages of the above-mentioned oils in unknown samples. The electronic-nose was therefore employed successfully for quantitative analysis of the concerned oil blends (i.e. for determination of unknown blend composition). The Chemometric methodology used for data processing and identification was Statistical Quality Control (SQC).
