Preparation of oil-free egg lecithin with a reduced cholesterol content

Preparation of oil-free egg lecithin with a reduced cholesterol content using liquified carbohydrate, whereby the lecithin containing egg oil is extracted using a separating column and propane or a mixture of propane and up to 25 weight % butane, as well as 5-40 weight % dimethyl ether (DME), and wh...

Beschreibung
Zusammenfassung:	Preparation of oil-free egg lecithin with a reduced cholesterol content using liquified carbohydrate, whereby the lecithin containing egg oil is extracted using a separating column and propane or a mixture of propane and up to 25 weight % butane, as well as 5-40 weight % dimethyl ether (DME), and where the gas pressure is 20-100 bar and the temperature 30-100 deg C. A light, low-viscosity melt is obtained at the head of the column which contains oil and cholesterol, and high-viscosity, lecithin containing phase, which is low in cholesterol and has the oil component removed, is obtained at the sump.
