“…These radiolytic products, such as n-alkenes, have been observed after the radiolytic treatment of peanuts (Park and Hwang, 1999), apricots and herbs (Kim et al, 2010). n-Alkanes and nalkenes from meat-derived triglycerides (Barba et al, 2012) have been reported as well as the formation of volatile aromatic compounds (Kim et al, 2005), and various alkyl lipids, including cyclobutanones (Blanch et al, 2009;Crews et al, 2012). Radiolytic cracking of heavy oils and bitumen has been demonstrated to be feasible, although the generation of light hydrocarbons is counterbalanced by heavy polymerization products (Lewan et al, 1991;Zaikin, 2008;Zaikin and Zaikina, 2013).…”

“…To date, only the Indian Group has reported the natural existence, and the need to improve analytical methods in order to resolve the emerging possibility that some non-irradiated foods may contain 2-ACBs has been emphasized 11) . In our previous paper, neither 2-DCB nor 2-dDCB was observed in any of the non-irradiated nutmeg samples by using GC-HRMS analysis 12) .…”

The natural existence of the irradiation markers, namely, 2-dodecylcyclobutanone (2-dDCB), 2-tetradecenylcyclobutanone (2-tDeCB), and 2-tetradecylcyclobutanone (2-tDCB) in cashew nut (Anacardium occidentale) has recently been reported. In this study, 2-dDCB, 2-tDCB and 2-tDeCB were extracted from cashew nut of 2 different origins using supercritical fluid extraction (SFE). The irradiated samples were analysed by gas chromatography-mass spectrometry, whereas the non-irradiated samples were analysed with high-resolution gas chromatography-mass spectrometry (GC-HRMS). 2-dDCB, 2-tDCB and 2-tDeCB were detected and identified in the irradiated samples at 1 kGy or greater. However, none of 2-ACBs was detected in the non-irradiated samples with GC-HRMS. The radioproduction yield of 2-alkylcyclobutanones (nmol/mmol precursor fatty acid/kGy) were 1.3, 1.3 and 1.7 for 2-dDCB, 2-tDCB and 2-tDeCB, respectively.

“…The determination of 2-DCB and 2-TCB is described in the European Standard Method EN 1785:2003 and consists of Soxhlet extraction by hexane of the lipid fraction containing the analytes, followed by purification by chromatography on Florisil Ò , and finally GC-MS detection (EN 1785(EN , 2003. This procedure shows different critical points, such as long and solventconsuming extraction and a complex clean-up step (Crews et al, 2012). For this reason, the European Standard EN 1785:2003 method is unsuitable for routine analysis; therefore, advanced analytical methods to International Journal of Food Science & Technology 2020 isolate and detect 2-ACBs have been developed (Gadgil et al, 2002;Obana et al, 2005;Soncin et al, 2012;Breidbach & Ulberth, 2016;Li et al, 2017;).…”

Summary A rapid and simple procedure to detect irradiated food containing fat is proposed. This method is based on HS‐SPME coupled with GC‐MS to determine the presence of a radiolytic product in irradiated meats: 2‐dodecylcyclobutanone (2‐DCB) and is proposed as an alternative to EN 1785:2003, which is a long and complex procedure. The qualitative confirmation method is validated on different type of meats: chicken, turkey, duck, beef, pork on both nonirradiated and irradiated samples at different dose levels (0.05, 0.12, 0.5, 1.0 and 3.0 kGy) with a biological X‐ray irradiator. The validation parameters investigated are selectivity, minimum dose level (MDL), limit of detection (LOD), sensitivity and specificity. The MDL and LOD values were 0.5 kGy and 5.0 ng mL−1, respectively, for all matrices. No false positives or false negatives occurred, and 100% of samples were correctly identified. The results show that HS‐SPME GC‐MS is suitable for routine analysis.
