Extraction process to improve the quality and yield of crude vegetable oils

Soybean solids and lecithin oils essentially free from objectionable flavors and odors are obtained by initially extracting undesirable lipid components from oil containing seed materials. These undesirable lipids can be extracted with an azeotropic mixture of hexane and alcohol. A debittered, high...

Beschreibung
Zusammenfassung:	Soybean solids and lecithin oils essentially free from objectionable flavors and odors are obtained by initially extracting undesirable lipid components from oil containing seed materials. These undesirable lipids can be extracted with an azeotropic mixture of hexane and alcohol. A debittered, high lecithin-containiing oil is obtained by admixing the resultant lipid extract with aqueous alcohol and then effectuating an oil phase separation therefrom. The oil, essentially free from the undesirable lipid contaminants, is recovered from the hexane-oil phase.
