This study aims to analyze 22 PAHs by QuEChERS coupled with GC\u2013MS\/MS in canned minced chicken and pork during processing. After marinating raw minced chicken and pork separately with a standard flavoring formula used for canning meat in Taiwan, they were subjected to different processing conditions including stir-frying, degassing and sterilizing at 115 \u00b0C\/60 min (low-temperature\u2013long-time, LTLT) and 125 \u00b0C\/25 min (high-temperature\u2013short-time, HTST). The quantitation of PAHs in these meat products revealed the formation of only three PAHs including acenaphthylene (AcPy), acenaphthene (AcP) and pyrene (Pyr) in canned minced chicken and pork during processing with no significant difference in total PAHs between the meat types. Analysis of PAH precursors showed the presence of benzaldehyde at the highest level, followed by 2-cyclohexene-1-one and trans,trans-2,4-decadienal in canned minced chicken and pork, suggesting PAH formation through the reaction of benzaldehyde with linoleic acid degradation products and of 2-cyclohexene-1-one with C4 compounds through the Diels\u2013Alder reaction, as well as the reaction of trans,trans-2,4-decadienal with 2-butene. Monounsaturated and polyunsaturated fatty acids were present in the largest proportion in LTLT-sterilized chicken\/pork, followed by HTST-sterilized chicken\/pork and raw chicken\/pork, and their levels did not show a high impact on PAH formation, probably due to an insufficient heating temperature and length of time. A two-factorial analysis suggested that PAH formation was not significantly affected by the sterilization condition or meat type. Principal component analysis corroborated the observed results implying the formation of PAHs in canned minced chicken\/pork under different processing conditions with an insignificant difference (p &gt; 0.05) between them, with the individual PAH content following the order of Pyr &gt; AcPy &gt; AcP.<\/jats:p>","DOI":"10.3390\/molecules29184372","type":"journal-article","created":{"date-parts":[[2024,9,16]],"date-time":"2024-09-16T10:56:57Z","timestamp":1726484217000},"page":"4372","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Analysis and Formation of Polycyclic Aromatic Hydrocarbons in Canned Minced Chicken and Pork during Processing"],"prefix":"10.3390","volume":"29","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4301-7614","authenticated-orcid":false,"given":"Baskaran Stephen","family":"Inbaraj","sequence":"first","affiliation":[{"name":"Department of Food Science, Fu Jen Catholic University, New Taipei City 242062, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-1327-8390","authenticated-orcid":false,"given":"Yu-Wen","family":"Lai","sequence":"additional","affiliation":[{"name":"Department of Food Science, Fu Jen Catholic University, New Taipei City 242062, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6313-8627","authenticated-orcid":false,"given":"Bing-Huei","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Food Science, Fu Jen Catholic University, New Taipei City 242062, Taiwan"},{"name":"Department of Nutrition, China Medical University, Taichung 404328, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,9,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"716","DOI":"10.1016\/j.trac.2006.05.010","article-title":"Analytical methods for polycyclic aromatic hydrocarbons (PAHs) in food and the environment needed for new food legislation in the European Union","volume":"25","author":"Wenzl","year":"2006","journal-title":"TrAC Trends Anal.
