| Popis: | In eastern Morocco, new cooperatives of citrus fruit technological transformation begin to be installed. The seeds resulting from these transformation processes remain without any valorization. This study concerns the physico-chemical characterization of three different citrus seed oils (Citrus limon (Citron), Citrus aurantium (Bigarade) and Citrus clementina (Clementine de Berkane)), cultivated in eastern Morocco. The seed oils were mechanically extracted by oil press and the oil yield, quality indices (acidity, peroxide, saponification, and refraction indices), polyphenol contents, antioxidant activity and fatty acid profile were analyzed. The mechanical yield varies between 15% for Bigarade seed oil and 29% for Lemon seed oil. The acidity, peroxide, saponification, and refraction indices varied between 0.55 - 0.57% of oleic acid, 5.77 to 10.34 meqO2/kg of oil, 116.67 and 173.53 mg KOH /g and 1.4699-1.4718 for the 3 studied seed oils, respectively. The polyphenols varied from 565 to 913 mg / 100g and the antioxidant activity ranged between 30 and 50%. The fatty acid profiles, of the analyzed citrus seed oils, presented 5 major fatty acids with the dominance of linoleic acid (C18: 2) which presented 34% for Clementine and Lemon seed oils and 35.5% for Bigarade seed oil.
