A quick discrimination of vegetable oil by solid-phase microextraction method

A new methodology capable of characterizing most volatile and less volatile minor edible oils components in a single chromatographic run without solvents or reagents. Detection of new components

“…The method used is based on that described by Mikuma and Kaneko (2010). The extraction of the oil components was carried out by solid-phase microextraction.…”

“…SPME by immersion of the fiber in a liquid phase followed by a chromatographic study has been used mainly for the determination of some types of contaminants and toxic substances, above all in water samples, (Mekiki, Kalogerakis, & Psillakis, 2006). Furthermore, Mikuma and Kaneko (2010) have proved the usefulness of this methodology to discriminate between vegetable oils based mainly on the abundance of a reduced number of compounds such as three or four sterols. A method derived from this latter is used in the present paper to prove its suitability in characterizing most of the minor volatile and less volatile edible oil components, and even to discover compounds not previously detected in edible oils.…”

Chemical Characterization of Cultivated Tagetes minuta L. by Use of Ultrasound-Assisted Head Space SPME and GC–MS

“…SPME has attracted increasing attention in environmental and food analysis because of its simplicity, efficiency, high precision, low detection limit, and ease of automation [24][25][26]. It has been used in many applications, including analysis of volatile and semi-volatile sulfur compounds in beer and Cheddar cheese [27], polycyclic musks in sewage sludge [28], nicotine in cigarette smoke [29], food taints [30], aldehydes in exhaled breath of patients with lung cancer [31], and codeine and morphine in human hair [32], for rapid discrimination of vegetable oil [33], and for analysis of water pollutants [34], aliphatic primary amines in wastewater [35], and volatile compounds in rice samples [36].…”
