摘要: For investigating the effects of degumming, neutralization, winterization and deodorization operations on composition sunflowerseed oil, samples were collected from each respective stage a commercial oil refining factory in Tekirdaǧ, Turkey. Based laboratory analyses, it was concluded that there no significant changes specific gravities, refractive indices, saponification numbers. Iodine values fatty acid compositions altered slightly during winterization. There gradual decrease throughout consecutive refining, free acids, phospholipids, unsaponifiables, tocopherols, sterols iron contents. Also, slight observed relative distribution pattern individual tocopherol sterol components. The overall quality, points oxidative stability nutritional status, not lower than original crude sunflower seed oil. Einflus von Raffination auf die chemische Zusammensetzung des turkischen Sonnenblumenols Um den Einflus (Entschleimung, Entsauerung, Entfarbung, Desodorisierung, Entstearinisierung) Sonnenblumenol zu studieren, wurden aus der Olraffinationsanlage Turkei, entsprechende Muster wahrend genannten Stadien entnommen. Nach Analysenergebnissen keine beachtenswerten Anderungen im spezifischen Gewicht, Brechungsindex und Verseifungszahl festgestellt. Entstearinisierung hatten geringe Jodzahl Fettsauren stattgefunden. In jedem aufeinanderfolgenden wurde eine allmahliche Abnahme an freien Fettsauren, Phospholipiden, Unverseifbarem, Tocopherolen, Sterinen auch Eisengehalt Auch relativen Verteilung individuellen Tocopherolen ermittelt. Im ganzen gesehen war Qualitat raffinierten Oles hinsichtlich Oxidationsstabilitat Nahrwert nicht geringer als Rohsonnenblumenoles.
