Description Crude soylecithin was extracted with carbon
dioxide at pressures of 120, 200, 240, 280 and 320 bar
(12, 20, 24, 28 and 32 MPa, respectively) and at a
temperature of 40 °C to obtain de-oiled lecithin. The
amount of phospholipids (acetone insoluble) increased
with increasing pressure. The carbon-dioxide-extracted lecithin (CDEL) was fractionated with alcohol into alcohol soluble and alcohol-insoluble fractions. Depending on the
pressure, the alcohol-soluble fraction of CDEL was found
to contain up to 70.0% phosphatidyl choline as against
21.1% present in crude lecithin. The alcohol-insoluble
fraction of CDEL was found to contain up to 37.1%
phosphatidyl inositol as against 12.3% in crude lecithin.
The chemical parameters of CDEL and the alcohol-soluble
and alcohol-insoluble fractions were evaluated.
