Abstract EN
This study aims to investigate the physicochemical characteristics, phenolics content, and oil composition of pomegranate oil seeds (PSO).
Quality indices, pigments, phenolics content, and antioxidant activity were determined.
PSO was fractioned into polar lipids: glycolipids (GL) and phospholipids (PL).
Sterols profile and fatty acids composition of total lipids (TL), GL, and PL were determined by GC/FID.
The free acidity, the peroxide value, and the specific extinction coefficients were, respectively, 1.69%, 3.42 in milliequivalents of active oxygen per kilogram of oil, 4.15, and 3.95.
PSO is rich in phenols (93.42 mg/Kg) but poor in pigments.
The sterols markers were β-sitosterol (77.94%), Δ5-avenasterol (7.45%), and campesterol (6.35%).
Oil content was 12.2%, wherein 23.9% were GL and 24.35% were PL.
TL were rich in unsaturated fatty acids (63.17%), while saturated fatty acids were more present in PL and GL (71.97% and 66.29%, resp.).
Conjugated fatty acids were about 13.30%, 2.03%, and 4.91%, respectively, in TL, PL, and GL.
The cis/trans ratio of TL, PL, and GL was, respectively, 49.82%, 42.91%, and 27.39%.
Monounsaturated fatty acids were more bound in PL, whereas polyunsaturated fatty acids were more bound in GL.
PSO is a good source of essential fatty acids, phenolics compounds, phytosterols, and lipid-soluble fractions.
