Deodorizing effect of coriander on the offensive odor of the porcine large intestine

The deodorizing effect of coriander (Coriandrum sativum L.) on the offensive odor caused by porcine large intestine was studied. Both 0.5 and 2.0g of coriander were found to deodorize the stench of 2.0g porcine large intestine almost completely, and the deodorant effect of coriander was maintained for 6 hrs or more even after the peculiar odor of the coriander disappeared. We detected four main compounds that contributed to the porcine large intestine odor: 4-Methylphenol (a sludge-like substance), unknown compound I (porcine large intestine-like), unknown compound II (a sludge-like substance) and Indole (excrement-like). Eleven main compounds of coriander odor were detected: Decanal, 2-Decenal, Undecanal, 2-Undecenal, 1-Decanol, (E)-2-Undecen-1-ol, 2-Dodecenal, (E)-2-Tetradecenal, Hexadecanal, Octadecenal and 9-Octadecenal. Although the four main compounds were not significantly decomposed by the coriander treatment, the coriander had a remarkable deodorant effect on the offensive odor emitted by the porcine large intestine.
