Analysis of Fatty Acids in the Oils in Tins of Sardines

Summary/Abstract: Fish meat is an as yet underappreciated and rarely consumed food product in Poland. Fatty fish meat, such as that of sardines, is especially interesting. The Polish market offers a particularly broad assortment of tinned sardines. The aim of this study was to determine, by means of gas chromatography, the fatty acid profile of oil in tins of sardines. 16 various tins from different producers were selected for the study. It was found that the concentration of saturated acids varied from 11.64% to 30.99%. The monoenoic acid content also varied. C18:1 (cis-0) acid content varied from 16.08% to 76.91%, while the total concentration of other acids was app. 5%. The trans fatty acid form of C18:2 (trans-9,12) was found in eight tests while the total concentration of acids from the n-6 family of acids varied from 5.40% to 62.28%. The ratio of n-3 to n-6 acid content ranged from 0.01 to 0.35, whilst the ratio of total fatty acid content to saturated fatty acid content varied from 2.23 to 7.59.
