The potential use of electronic nose in detecting adulteration in VCO oil was studied by Marina (2008). In thestudy, zNose electronic nose with surface acoustic wavewas used to detect adulteration of palm kernel olein inVCO. Principal component analysis (PCA) was used to differentiate between pure and adulterated samples. The PCAprovided good separation of samples with 74% of the variation accounted for the PC1 and 17% accounted for thePC2. Pure samples formed separated cluster from all adulterated samples.
