Abstract :
Supercritical fluid extraction (SFE) using carbon dioxide was used to detect the adulteration of black pepper powder with ground papaya seed. Thin-layer chromatography analysis of the SFE extracts showed a fluorescent band at 366 nm at Rf 0.172 that proved to be a promising marker for the presence of papaya seed powder in black pepper powder even at a level of 20 g kg-1. The straight-chain aldehydes n-nonanal, n-decanal and n-dodecanal were tentatively identified by gas chromatographymass spectrometry analysis as components of this fluorescent marker and were not present in black pepper extracts.
