Abstract
A process for releasing and extracting phosphatides from a phosphatide-containing matrix. The process includes (i) contacting the phosphatide-containing matrix with a solvent and a metal salt to release phosphatides from the matrix and form a phosphatide enriched solvent portion and a phosphatide depleted matrix portion, (ii) separating the phosphatide enriched solvent portion from the phosphatide depleted matrix portion, and (iii) recovering the phosphatides from the phosphatide enriched solvent portion.

A process for releasing and extracting phosphatides from a phosphatide-containing matrix comprising:
- (a) contacting the phosphatide-containing matrix with a solvent and a metal salt to release phosphatides from the matrix and form a phosphatide enriched solvent portion and a phosphatide depleted matrix portion,
- (b) separating the phosphatide enriched solvent portion from the phosphatide depleted matrix portion, and
- (c) recovering the phosphatides from the phosphatide enriched solvent portion.
A process for releasing and extracting phosphatides from a phosphatide-containing matrix which has not been contacted with hexane comprising:
- (a) contacting the phosphatide-containing matrix with a solvent and a metal salt to release phosphatides from the matrix and form a phosphatide enriched solvent portion and a phosphatide depleted matrix portion, wherein the solvent is selected from a C1-3 alcohol or a combination of a C1-3 alcohol and water,
- (b) separating the phosphatide enriched solvent portion from the phosphatide depleted matrix portion, and
- (c) recovering the phosphatides from the phosphatide enriched solvent portion, thereby producing a hexane-free phosphatide product.
