Abstract

Abstract: The headspace-solid phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) technique was used to investigate 2-dodecylcyclobutanone (2-DCB) and 2-tetradecylcyclobutanone (2-TCB) as X-ray induced markers in irradiated dairy products. For the first time, an intensive study on several types of milk and cheeses, was carried out to evaluate both the suitability of this analytical technique for dairy products and how different factors related to these types of food, such as matrix composition, ripening time and technological processes, can affect 2-DCB and 2-TCB extraction. The results demonstrated that these analytes were identified in all types of irradiated samples, even if 2-TCB showed a lower sensibility than 2-DCB. Moreover, for both analytes, increasing irradiation dose over the experimental range of 0.5–5.0 kGy, a linear response was observed in all the matrices studied. The minimum dose level (MDL) and limit of detection (LOD), in irradiated and spiked samples, were 0.5 kGy and 5.0 μg L −1, respectively. Furthermore, linear correlation between 2-DCB and 2-TCB contents was demonstrated. Finally, chemometric analysis highlighted the influence of ripening time and dairy technological processes on extraction capability of the two investigated analytes.

Fat and moisture contents did not affect the 2-DCB and 2-TCB extraction capability. Technological processes and ripening time influenced the 2-DCB and 2-TCB extraction.
