Abstract

The fatty acid composition of few Macedonian edible oils, including sunflower, pumpkin seed, flax, rapeseed and sesame seeds, was determined using GC-FID analysis after derivatisation with BF3-methanolic solution. Six different types of fatty acids (FAs) were found in the oils samples. Palmitic acid (C16:0) and stearic acid (C18:0) were common in all saturates. Myristic acid (C14:0) was present in the sunflower and pumpkin seed oil. Oleic acid (C18:1), linoleic acid (C18:2) and -linolenic (C18:3) were dominant in the unsaturated FAs of all oils. In terms of variety, linoenic acid (C18:3) was the main unsaturated FA in flax seed oil (56.2 % of total FA), oleic acid (C18:1) dominated in rapeseed and sesame oils (65.3 and 43 % of total FA, respectively) and linoleic acid (C18:2) was the dominant compound in sunflower and pumpkin seed oil (59.2 and 59.5 % of total FA, respectively). Principal Component Analysis was employed, showing separation and grouping of the oils according to their variety.
