Özet

In this research, FA composition and total trans FA contents of 16 different brands of margarine (8 hard-type and 8 soft-type) sold in Turkey were determined by capillary GLC method. According to the results, the contents of saturated FA, monounsaturated FA, and PUFA were within the ranges of 23.9-32.3, 44.0-61.9, and 14.2-24.1%, respectively, in hard-type margarines, and 27.0-39.9, 21.0-40.9, and 32.0-53.79%, respectively, in soft-type margarines. Hard-type margarines contained total trans FA concentrations of 20.1-34.3%, whereas softtype margarines contained less than 8.9% total trans FA. C-18:1 trans acid content was within the range of 18.5-29.8% in hard type margarines, and it was significantly higher than the range in soft margarines (0.7-8.1%). C-18:1 trans acid was the in all. or trans FA in all margarines, and C-18:3 trans acid concentrations were less than 0.2%.
