dc.abstract.enCurrently, alternative plant oils with pro-health properties are sought. The aim of the present study was to investigate the effect of feeding strawberry, raspberry and rapeseed oils in rats’ diet on the fatty acid profile of muscle tissue. Adult rats were randomly divided into 4 groups (n=7) and fed with the addition of rapeseed, raspberry or strawberry seed oil, respectively, or control group. After a 6-week treatment period, the fatty acid profile in m. latisssimus dorsi, was analyzed using gas chromatography. The dietary strawberry or raspberry seed oil led to a significant increase in C-18:2 n-6 ad C-18:3 n-3 level in muscle fat when compared to control group. At the same time, in the group receiving raspberry oil, an unfavorable phenomenon of lowering the EPA content was observed, while a tendency towards a decrease in DHA level was observed in groups supplemented with both raspberry and strawberry oil. Both oils as a source of PUFA n-3 and n-6, increased ALA n-3 and LA n-6 fatty acids in latissimus dorsi muscle, but due to different activity of enzymes taking apart in conversion of polyunsaturated fatty acids to their long chain derivatives in rats, the research on pig model would be advisable.
