Volatile profiling of durum wheat kernels by HS–SPME/GC–MS

European Food Research and Technology, 2016
This work aimed at developing a HS–SPME/GC–MS method for the extraction and analysis of volatile compounds from the kernels of durum wheat. Fiber coating, temperature and time of extraction were evaluated. Moreover, the method was used as a tool for varietal characterization.

Rearrangement ofp-menthane terpenes by Carboxen during HS-SPME

Journal of Separation Science, 2002
The commercially available 75 μm Carboxen-Polydimethylsiloxane (PDMS) fibre for solid phase microextraction (SPME) has been shown to rearrange some monoterpenoids to p-cymene during headspace (HS)-SPME analysis. Ten commonly encountered monoterpenoids varying in structural and/or functional group were used as test compounds. The p-menthane hydrocarbons

Flavor evolution and identification of the warmed-over flavor (WOF) in pre-cooked goose meat by means of HS-SPME-GC-MS and GC-IMS.

Food Chemistry
This study explored the flavor evolution of pre-cooked goose meat during storage, focusing on lipid oxidation's impact on warmed-over flavor (WOF). Using electronic nose, GC-IMS, and SPME-GC-MS to characterize volatile organic compounds (VOCs), 60 VOCs ...

Volatiles in Potentilla discolor by HS-SPME-GC-MS

Chemistry of Natural Compounds, 2014
Potentilla discolor Bunge (Rosaceae) is a perennial herb widely distributed in China. The full herb, as a traditional Chinese medicine, clears heat and toxicity, treats hemostasis, and has detumescent effects in diseases such as hematemesis, hemafecia, metrorrhagia, dysenteria, and malaria [1].
