Indexing of fatty acids in raw turkey meat and products for their characterization in a healthy diet
The aim of this work was to determine the fatty acid profile and health lipid indices of fresh turkey meat, as well as products obtained from turkey meat, i.e. turkey sausage and pate. Turkey breast muscles were cut from the side of the carcass, separately vacuum packed and stored in a refrigerator before analysis. Sausages and pate were produced from turkey meat using a technological process. The fatty acid profile of the samples was determined by gas chromatography with a flame ionization detector (GC/FID), and lipid indices were calculated based on the composition. Turkey muscle had a higher percentage of C16:0 and C18:0 than turkey sausage and pate. A significantly higher proportion of saturated fatty acids (47.9%) than in sausage and pate, 27.2 and 8.9%, respectively, characterized turkey muscle. The lowest determined proportion of polyunsaturated fatty acids for turkey muscle was 12.0%. The atherogenicity index was satisfactory for all three tested products, while the thrombogenicity index was satisfactory only for the tested raw turkey muscle meat (1.656).
