Sažetak
Cilj ove studije je da pruži informacije o profilu masnih kiselina različitih masnih depoa - potkožni (gornji i unutrašnji slojevi leđne slanine) i intramuskularni (m. longissimus dorsi) istočno-balkanske rase svinja. Životinje su gajene u uslovima slobodnog držanja i zaklane u proseku žive mase od 107 ± 1,65kg. Rezultati studije su pokazali da različiti depoi masnog tkiva kod svinja imaju različit metabolizam lipida i stoga se razlikuju u sastavu masnih kiselina. Intramuskularna mast je imala značajno veći sadržaj zasićenih C16: 0 i C18: 0 (P<0,001), kao i C16:1 (P<0.001) nego potkožno tkiva. Što se tiče sadržaja polinezasićenih masnih kiselina, potkožno tkivo prikazuje znatno veći sadržaj i C18:2 i C18:3 (P<0,001) u odnosu na intramuskularnu masti u m. longissimus dorsi. Razlike između potkožnog masnog tkiva i intramuskularne masti u pojedinim masnim kiselinama određuju i sličan trend u ukupnom sadržaju zasićenih i polinezasićenih masnih kiselina. Značajne razlike između slojeva leđne slanine su otkriveni za C16:1, C18:0 i C18:3 (P<0,001). Stearinska kiselina (C18: 0) prikazuje veći sadržaj u unutrašnjem, a C16:1 i C18:3 su imali veći udeo u spoljašnjem sloju leđne slanine istočno-balkanskih svinja. Osim C 20:2, polinezasićene masne kiselina dugog lanca n-6 i n-3 su imale značajno veće razmere u intramuskularnoj masti, međutim, statistički signifikantne razlike nisu utvrđene između dva sloja leđne slanine.
