20.500.12556/RUL-133853 Fatty acid and stable carbon isotope composition of Slovenian milk year, season, and regional variability This study examined the percentage and stable isotope ratios of fatty acids in milk to study seasonal, year, and regional variability. A total of 231 raw cow milk samples were analyzed. Samples were taken twice per year in 2012, 2013, and 2014, in winter and summer, covering four distinct geographical regions in Slovenia: Mediterranean, Alpine, Dinaric, and Pannonian. A discriminant analysis model based on fatty acid composition was effective in discriminating milk according to the year/season of production (86.9%), while geographical origin discrimination was less successful (64.1%). The stable isotope composition of fatty acids also proved to be a better biomarker of metabolic transformation processes in ruminants than discriminating against the origin of milk. Further, it was observed that milk from Alpine and Mediterranean regions was healthier due to its higher percentage of ω-3 polyunsaturated fatty acid and conjugated linoleic acid. milk fatty acids stable carbon isotope composition GC-FID CSIA statistical analyses true false true Angleški jezik Ni določen Članek v reviji 2021-12-17 09:03:01 2021-12-17 09:03:01 2022-09-13 03:52:48 0000-00-00 00:00:00 2020 0 0 18 str. iss. 12, art. 2892 Vol. 25 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 502/504 1420-3049 10.3390/molecules25122892 20851715 RAZ_Potocnik_Doris_2020.pdf RAZ_Potocnik_Doris_2020.pdf 1 5C5DBFD1DBBC418513DDB2A141F30FC4 43a4de97fffd444cc9c0833df5fa46e387613f053e1d9f3c7b73a793fc9dbc04 40136b9d-5f10-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=152205 https://www.mdpi.com/1420-3049/25/12/2892 0 c394a108-5f0f-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=152204 Biotehniška fakulteta 0 0 0
