Analysis of flavor volatiles of some Iranian rice cultivars by SPME-GC-MS
A combined gas chromatography–mass spectrometry (GC–MS) with headspace solid-phase microextraction (HS-SPME) method has been employed for the analysis of the flavor volatiles of some Iranian rice cultivars (Domsiah, Deylamani, Hashemi, Shirodi and Tarom). The samples were grown in different cities of Mazandaran province. The sampling procedure and chromatographic conditions were same for all sa...
متن کاملAssessment of Flavor Volatiles of Iranian Rice Cultivars during Gelatinization Process
ABSTRACT: A combined gas chromatography-mass spectrometry (GC-MS) with headspace solid-phase micro extraction (SPME) method has been employed for the analysis of the flavor volatiles of three different rice cultivar, including two modified Iranian rice cultivars and Hashemi rice cultivar during gelatinization. The proposed combination provided a powerful system for easy and rapid screening of a...
متن کاملIdentification of Honey Volatile Components by Solid Phase Microextraction (spme) and Gas Chromatography/mass Spectrometry (gc/ms)
Volatile compounds in honey samples of different botanical origins were investigated. Solid phase microextraction (SPME) and gas chromatography-mass spectrometry (GC/MS) revealed a total of 86 compounds in the headspace of 4 types of honey – multifloral, heather, buckwheat and lime-honeydew. The chemical composition of the headspace was very diverse, owing to the presence of compounds from diff...
متن کاملPreparation of Solid Phase Microextraction (SPME) Probes through Polyaniline Multiwalled Carbon Nanotubes (PANI/MWCNTs) Coating for the Extraction of Palmitic Acid and Oleic Acid in Organic Solvents
A fiber coating from polyaniline (PANI) was electrochemically prepared and employed for Solid phase micreoextraction (SPME). The PANI film was directly electrodeposited on the platinum wire surface using cyclic voltametry (CV) technique. The same method was applied for the preparation of SPME fiber coated by polyaniline multiwalled carbon nanotubes (PANI/MWCNTs) composite. The concentration of ...
