Performance evaluation of non-targeted peak-based cross-sample analysis for comprehensive two-dimensional gas chromatography–mass spectrometry data and application to processed hazelnut profiling

Flavor of roasted peanuts ( Arachis hypogaea ) — Part II: Correlation of volatile compounds to sensory characteristics

“…In addition, improved analytical techniques such as two dimensional gas chromatography that use consecutive separation columns, coupled with advanced fingerprinting tools such as sensomics promise exciting prospects in both reducing the detection thresholds and in better identifying candidate compounds, making the recombination studies more focused and easier to undertake (Cordero et al, 2010;Cordero, Kiefl, Schieberle, Reichenbach, & Bicchi, 2015;Kiefl et al, 2012).…”

Sense of smell and volatile aroma compounds and their role in the evaluation of the quality of products of animal origin – a review

“…in nuts (Cordero et al, 2010;Kiefl et al, 2012;Kiefl and Schieberle, 2013), olive and oils (Purcaro et al, 2014;Tu et al, 2014), coffee (Majcher et al, 2013), cocoa (Nicolotti et al, 2013), strawberries (Samykanno et al, 2013), mushrooms (Grosshauser and Schieberle, 2013;Usami et al, 2014), teas and herbs (Baba and Kumazawa, 2014;Lv et al, 2014;, as well as in beverages (Butkhup et al, 2011;Avellone et al, 2013;Inui et al, 2013;Langos et al, 2013).…”

“…It is based on Unauthenticated Download Date | 8/25/15 2:07 PM sorption of substances found over the surface of a sample matrix to the extraction phase dispersed on a solid support -fibre (Pawliszyn, 2000). SPME performs well in rapid fingerprinting and has found numerous applications (Rochat et al, 2007;Leroy et al, 2009;Cordero et al, 2010;Kiefl et al, 2012;Bordiga et al, 2013;Rivellino et al, 2013;Bordiga et al, 2014;Dugo et al, 2014;Lv et al, 2014;Tu et al, 2014;Lv et al, 2015). Less known are other microextraction techniques, such as single drop microextraction (SDME), hollow fiber liquid phase microextraction (HF-LPME), dispersive liquid-liquid microextraction (DLLME) and gas purge microsyringe extraction (GP-MSE, Yang et al, 2013).…”

Comprehensive Two-dimensional Gas Chromatography for Analysis of the Volatile Compounds and Fishy Odor Off-flavors from Heated Rapeseed Oil

“…This technique has a higher peak capacity, compared to conventional 1D-GC, because the high surface of GC × GC chromatogram can be used for compounds separation. Moreover, GC × GC enhances sensitivity using a step of refocusing of analytes [18,19]. Thus, coelutions are limited and the analytes are arranged with organized structures over the chromatogram, which allows a reliable identification [20].…”
