Abstract
The present invention relates to an apparatus and method for separating glycoglycerolipids and also glycoglycerolipids and glycosphingolipids from a lipid phase that contains glycoglycerolipids and acyl glycerides or glycoglycerolipids and glycosphingolipids and acyl glycerides, in mild conditions with no hydrolysis and while at the same time effectively depleting the lipid phase of said glycoglycerolipids, glycoglycerolipids and glycosphingolipids and their accompanying substances using an aqueous extraction process.
Claims15
A method for the hydrolysis-poor separation of glycoglycerolipids from a lipoid phase which contains glycoglycerolipids and acylglycerides, comprising the steps:
- A1) providing a lipoid phase containing glycoglycerolipids and acylglycerides,
- B1) adding to the lipoid phase an aqueous phase containing anions of at least one salt which has a solubility of at least 30 g/l in water at 20° C. and which, upon dissociation in water, forms carbonate (CO32−), bicarbonate (HCO3−), metasilicate (SiO32−), orthosilicate (SiO44−), disilicate (Si2O52−), trisilicate (Si3O72−), acetate (CH3COO−), borate (BO33−), and/or tartrate (C4H4O62−);
- C1) mixing the lipoid phase and the aqueous phase;
- D1) separating the glycoglycerolipid-rich aqueous phase and obtaining a glycoglycerolipid-poor lipoid phase;
- and
- D2) recovering the glycoglycerolipids from the separated glycoglycerolipid-rich aqueous phase.
