Determination of 11.14 eicosadienoic fatty acid (C20:2) in food By Gas Chromatography (GC) method was conduct. Isolation of the fat fraction of its fatty acid composition as its methyl esters. The extract fat was hydrolized and the resulting fatty acids were esterified to methyl esters using methanol and sulfuric acid.
By analyzing different kind of fats, i.e. those from chicken, beef, pork, it was found that the 11.14 eicosadienoic acid (C20:2) may be used as an indicator for the presence of pork fat in both raw and cooked food such fried noodle, sausage and meatball.
C20:2 contained in sausage and meatball sample was 0.1873+0.01% and 0.1690+0.02%.
The performance of determination method on GC optimum condition was range of linear dynamic calibration curve 0,040 ïg to 0.600 ïg, detection limit 0.030 ïg, accuracy 3.28% precision 3.09% and sensitivity (48.7 + 0.7)104 ïg-1. Recovery of 0.2 ïg C20:2 in sausage sample was 98.0 + 1.4% and of 0.2 ïg C20:2 in Meatball sample was 98.3 + 1.6%. this method did not contain systematic bias.
