Sažetak
It has long been known that fatty acids (FA) are essential for maintaining the health of the human body. The amount and composition of fatty acids in our body depends, among other things, on the composition of the food we consume, so it is necessary to monitor the food quality. Chicken meat and eggs are often consumed and are important sources of fatty acids. The composition of the feeding mixture for chickens affects the FA profile found in chicken meat and eggs, therefore it is necessary to control the composition of the feeding mixture. Three methods of FA extraction (Soxhlet, microwave and ultrasound-assisted extraction) were applied to 6 feed mixtures and compared. After Soxhlet and ultrasound-assisted extraction, the solvent was removed and samples were prepared according to a standard Fatty acid methyl ester (FAME) boron trifluoride method, while after microwave extraction, the samples were ready for the analysis by gas chromatography (GC). The significance of these comparisons lies in the, shortening of the sample preparation time and the greater number of peaks detected. Microwave extraction resulted in the lowest number of peaks detected, Soxhlet extraction showed a slightly higher number of peaks while ultrasound-assisted extraction gave the best results with the highest number of total FA detected.
