Volatile compounds of Baltic herring analysed by dynamic headspace sampling–gas chromatography–mass spectrometry

Effect of storage period before reheating on the volatile compound composition and lipid oxidation of steamed meat of yellowtail Seriola quinqueradiata

“…Of the volatile compounds identified in this study, propanal, 2-ethyl furan, 2,3-pentadione, (E)-2-pentenal, 1-penten-3-ol, (E)-2-hexenal, (E)-2-penten-1-ol, (E,E)-2,4-hexadienal, (E,Z)-2,4-heptadienal, 1,5-octadien-3-ol, (E,E)-2,4-heptadienal, (E,Z)-3,5-octadien-2-one, and (E,Z)-2,6-nonadienal are generated from n-3 PUFA oxidation; hexanal, heptanal, 1-pentanol, and 1-octen-3-ol are generated from n-6 PUFA oxidation; and octanal and nonanal are generated from n-9 PUFA oxidation [8,[27][28][29][30]. We have previously reported that the main volatile compounds produced by OM of raw yellowtail during short-term cold storage are propanal, hexanal, 2,3-pentadione 1-penten-3-ol, and 1,2,4-triethyl benzene and those of DM are propanal, hexanal, 1-penten-3-one, 2,3-pentadione, and 1-penten-3-ol.…”

Characterization of Volatile Compounds in Chilled Cod (Gadus morhua) Fillets by Gas Chromatography and Detection of Quality Indicators by an Electronic Nose

“…Their levels did not appear to increase until after the end of shelf life was reached ( Table 1). Therefore, they did not appear to be useful as indicators of spoilage during chilled storage of the cod fillets, but aldehydes have been suggested as indicators of spoilage in fatty species (20). Oxidation of fatty acids contributes to the rancid odors of fish with the formation of aldehydes such as hexanal, 2,7-heptadienal, and 2,4,7-decadienal (35).…”

Determination of carbonyl compounds in fish species samples with solid-phase microextraction with on-fibre derivatization

“…Several analytical methods for determining volatile compounds in fish samples have been developed using gas chromatographic methods such as simultaneous steam distillation with solvent extraction (SDE) (Prost, Serot, & Demaimay, 1998;Varlet, Knockaert, Prost, & Serot, 2006) or static (SHS) and dynamic (DHS) headspace methods (Alasalvar, Taylor, & Shahidi, 2005;Aro, Tahvonen, Koskinen, & Kallio, 2003;Frankel, Hu, & Tappel, 1989;Girard & Nakai, 1994;Hallier, Serot, & Prost, 2004;Medina, Satué -Gracia, & Frankel, 1999). SHS lacks of analyte preconcentration and DHS requires complicated and expensive equipments, having low suitability for routine analysis.…”
