Abstract

Meadowfoam (Limanthes alba) is an alternative oilseed crop that has application in personal care products. Offensive odor development in refined meadowfoam oil can be a problem for processors and formulators. To identify possible sources of the odor, the headspace above refined and deodorized meadowfoam oils was examined. Compound analyses were based on solid-phase microextraction (SPME) and Gas Chromatography–Mass Spectroscopy (GC–MS) techniques. Hexanal, heptanal, octanal, and nonanal were detected in the headspace of malodorous samples. Nonanal was also detected in the headspace of non-malodorous meadowfoam oil after a 4 week period at 60 °C.
