Fatty Acid Profile of Lipids of Fermented Sausages with Flaxseed Added

Abstract

The study examined the fatty acid profile of fermented sausages in which one part of backfat (making up 5%, 7% and 9% of the control treatment formulation) was replaced with flaxseed oil pre-treated with alginate and soy protein isolate. Increase in the content of pre-treated flaxseed oil had a significant effect on the fatty acid profile, which progressively changed with the increase of the oil content: saturated fatty acid content, content of oleic and total monounsaturated fatty acids were significantly lower while the content of α-linolenic acid increased multiple times (15–40 times) with the addition of flaxseed oil. Fermented sausages with flaxseed oil had significantly favorable PUFA/SFA and n-6/n-3 ratios.

U ovom ogledu ispitivan je sastav masnih kiselina fermentisanih kobasica kod kojih je deo čvrstog masnog tkiva (ČMT, koje čini 5, 7 i 9% nadeva) zamenjen lanenim uljem pripremljenim kao alginatni gel i emulzijom sa izolatom proteina soje. Zamena dela ČMT-a lanenim uljem imala je značajan uticaj na sastav masnih kiselina koji se progresivno menjao sa povećanjem sadržaja ulja: sadržaj zasićenih masnih kiselina, oleinske i ukupnih mononezasićenih masnih kiselina je značajno smanjen dok je sadržaj α-linolenske kiseline višestruko veći (15–40 puta) kod varijanti s lanenim uljem. Fermentisane kobasice sa lanenim uljem imale su značajno povoljnije odnose PUFA/SFA i n-6/n-3.
