Abstract
The chemical properties, mineral contents, fatty acid and tocopherol contents of seed and seed oils of some citrus genus provided from several locations in Turkey and Saudi Arabia were determined. While Ca contents of seeds were between 5018 mg/kg (Kütdiken lemon) and 7619 mg/kg (kinnow mandarin), K contents of seeds varied between 7007 mg/kg (Orlando orange) and 10334 mg/kg (kinnow mandarin). Glucose and fructose contents of citrus seed samples varied between 3.75 g/kg and 5.75 g/kg, and 4.09 g/kg and 6.03 g/kg. Palmitic, oleic and linoleic acids were established as dominant fatty acids. Palmitic, oleic and linoleic acid contents of citrus seed oils varied between 19.6% (Kütdiken lemon) and 26.2% (pineapple orange), 21.3% (kinnow mandarin) and 31.4% (Kütdiken lemon) and 32.3% (Kütdiken lemon) and 43.7% (kinnow mandarin), respectively. The total amount of tocopherols of Turkish citrus oil varied between 0.5 mg/100 g (Fremont mandarin) and 18.8 mg/100 g (bitter orange).
