Abstract | In situ transesterification and capillary GLC were performed for fatty acid composition determination (C13-C24) of colostrum from 41 Slovenian mothers. According to regional areas, there were differences (P=0;0001 and P=0,0046) in contents of 18:2 n-6 (12,62-17,31 % wt/wt) and 18:3n-3 (0,70-1,07 % wt/wt), the linoleic/alpha-linolenic ratio remaining unchanged (15,83 in Celje; 16,31 in Ljubljana and 17,88 in Koper; ns) Colostrum from rural compared to urban area contained higher (P = 0,0260) content of 18:1n-9 (36,85 vs. 34,94 % wt/wt). There was a positive correlation between linoleic and alpha-linolenic acid (P=0,0001; r=0,82) and between sum of n-3 LCP and n-6 LCP (P=0,0001; r =0,77). Comparing to the composition of colostrum in other countries, the colostrum of Slovenian women contained low content of saturated (37,68 % wt/wt) and high content of polyunsaturated fatty acids (21,82 % wt/wt), especially linoleic (15,25 % wt/wt) and alpha-linoleic acid (0,91 % wt/wt), and sum of fatty acids of n-3 and n-6 family. Linoleic/alpha-linoleic acid ratio (16,76) was higher as recommended by ESPGAN (5 - 15), n-6 LCP/n-3 LCP ratio was very high (3,25), especially due to high content of linoleic acid and sum of n-6 LCP (4,07 wt. %). | |
