Irradiated ground beef patties: Dose and dose-age estimation by volatile compounds measurement

Volatile profile, lipid oxidation and protein oxidation of irradiated ready-to-eat cured turkey meat products

“…This could be related to the chopping step involved in producing sausages (Boles et al, 1998). During that procedure, a proteinprotein cross linkages are formed and more amino acid residues, including lysine, arginine, proline and threonine, which are prone to be oxidized (Panseri et al, 2015), are exposed to air and accelerated protein oxidation.…”

Development of a robust HS-SPME-GC-MS method for the analysis of solid food samples. Analysis of volatile compounds in fresh raw beef of differing lipid oxidation degrees

“…However, PDMS/DVB was chosen for two reasons. It was the one which extracted the greater number of target aroma compounds selected, having regard to the scientific literature of raw beef (Casaburi, Piombino, Nychas, Villani, & Ercolini, 2015;Insausti, Beriain, Gorraiz, & Purroy, 2002;Panseri, Chiesa, Biondi, Rusconi, Giacobbo, Padovani, et al, 2015;Perez, Rojo, Gonzalez, & De Lorenzo, 2008;Saraiva, Oliveira, Silva, Martins, Ventanas, & Garcia, 2015;, and the intensity of oxidation-related carbonyl compounds was higher in the chromatograms obtained with this fibre, a result also observed for other matrices (Bueno, Zapata, & Ferreira, 2014).…”

Rapid Identification Method for Gamma-Irradiated Soybeans Using Gas Chromatography–Mass Spectrometry Coupled with a Headspace Solid-Phase Microextraction Technique

“…In this context, the headspace solid-phase microextraction (HS-SPME) technique is an effective alternative approach to overcome the limitations of the conventional methods. Several studies have demonstrated that the headspace solid-phase microextraction gas chromatography/mass spectrometry (HS-SPME-GC/MS) analysis can be used as a rapid identification method for 2-dodecylcyclobutanone (2-dDCB) in ground beef, beef patties, cooked ham, and sliced dry-cured ham irradiated at doses higher than 0.5 kGy. − However, to the best of our knowledge, this technique has not been applied to identify irradiated soybeans. Furthermore, it should be possible to detect soybeans irradiated at doses lower than 0.5 kGy using HS-SPME-GC/MS because the usual irradiation dose applied in quarantine treatment for inactivation of most insects is 0.4 kGy …”
