Volatile compounds were determined using headspace solid phase microextraction coupled to gas chromatography\/mass spectrometry. Results showed that the most dominant volatiles were 2,2,4,6,6-pentamethyl-heptane, hexanal, 1-octen-3-ol, 1-hexanol, carbon disulfide and p-cymene. Volatile compound content was increased during storage time. However, statistically significant differences were recorded only for hexanal, heptanal, and nonanal (p &lt; 0.05). Additionally, the evolution of aldehydes during storage recorded a positive Pearson\u2019s correlation (r) (p &lt; 0.05), whereas hexanal to nonanal, heptanal to nonanal, octanal to nonanal ratios, along with the sum of aldehydes to nonanal ratio, were positively correlated (r = 0.83\u20131.00) with the degree of oxidation (mg malonic dialdehyde per kg of lamb meat). A perfect Pearson\u2019s correlation (r = 1) was obtained for the ratio hexanal to nonanal. Therefore, this ratio is proposed as an indicator of lamb meat freshness and overall quality.<\/jats:p>","DOI":"10.3390\/foods7030040","type":"journal-article","created":{"date-parts":[[2018,3,16]],"date-time":"2018-03-16T04:22:59Z","timestamp":1521174179000},"page":"40","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":85,"title":["Volatile Profile of Raw Lamb Meat Stored at 4 \u00b1 1 \u00b0C: The Potential of Specific Aldehyde Ratios as Indicators of Lamb Meat Quality"],"prefix":"10.3390","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3488-2684","authenticated-orcid":false,"given":"Ioannis","family":"Karabagias","sequence":"first","affiliation":[{"name":"Laboratory of Food Chemistry, Department of Chemistry, University of Ioannina, 45110 Ioannina, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,3,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"436","DOI":"10.1016\/j.jfca.2006.09.001","article-title":"Preliminary study of the volatile fraction in the raw meat of pork, duck and goose","volume":"20","author":"Soncin","year":"2007","journal-title":"J.
