ABSTRACT
The effect of sunflower seeds on the fatty acid composition of lipid fraction from pork ham muscle has been studied. Forty-eight Landrace pigs being twenty-four castrated males and twenty-four females were assigned in groups of twelve to four diets. Muscles are obtained from animals fed on diets with the same ingredients excepted addition of sunflower seed (SS) (diet without SS, 5%, 10% and diet with 20% of SS) in substitution of corn and soybean meal (control) in feeds. The ratio polyunsaturated fatty acids to saturated fatty acids (PUFA/SFA) in pork ham for fat in muscle tissue was markedly modified by dietary sunflower seeds administration, which was due to the increase in the C18:2n-6 and the decrease in the C16:0 and C18:0. The content of C18:2n-6 increased from 11.7% in control group to 29.5% in the 20% sunflower seeds group. The content of saturated fatty acids, C16:0 and C18:0 decreased from 23.5% and 11.6% in control group to 16.8% and 9.3% in the 20% sunflower seeds group, respectively. The addition of sunflower seeds produced a significantly (P
