Abstract
The invention relates to oil-free glycerophospholipid formulations which contain a homogeneous mixture of glycerophospholipids and an anhydrous, liquid polyol compound such as glycerol in a molar ratio of 1:0.1 to 1. These formulations are produced, eg, by extracting a starting material consisting of an oil-containing glycerophospholipid (mixture) and the polyol component with a compressed hydrocarbon (mixture) in a rectifying column. The oil-free formulation can be obtained from the melt at the bottom of the column in the form of free-flowing powder, which is ideally suited for stabilising oil-in-water emulsions.
