Does palm oil contain Sudan IV dyes?

By measuring and analyzing the SERS spectra of Sudan IV, prepared palm oil and other palm oil samples, we were able to detect traces of Sudan IV dyes in all four of the palm oil samples provided for analysis. This confirms the prior knowledge of adulteration in them.

Is Sudan IV a non-adulterated palm oil?

Sudan IV is taken as a referential point also and is centered at the origin of the graph. FDA samples 2, 3, and 4 are also in another quadrant than the control point. They can be considered as adulterated. The FDA 1 sample has a response in the same quadrant than the control point, which means it is probably a non-adulterated palm oil.

Is Sudan IV present in edible palm oil samples?

Surface enhanced Raman spectroscopy (SERS) coupled with chemometric methods was applied to detect the presence of Sudan IV in some edible palm oil samples. We studied the samples within the 1200¨C1800?cm ??1 Raman frequency range. In predicting adulteration, we used 1388?cm ??1 Raman peak that is associated with Sudan IV as our marker.

What is the principal component analysis of palm oil?

Principal component analysis. PCA scores plots of authentic palm oil and the different preparation with SUDIII (ST3PM i H), SUDIV (ST4PM i H), and acetone (STAPM i H), and the FDA palm oil samples: (a) adulteration with Sudan III and (b) adulteration with Sudan IV. Insets are the skeletal formula of the Sudan dyes.
