Abstract:
1. A process for the preparation of phosphatides, or the salts thereof, the process comprising the steps of: (a) using at least one raw material lecithin as a substrate and a water-insoluble surfactant-matrix material having a particulate size greater than about 0.01 mm; and (b) enzymatically processing said at least one raw material lecithin with said water-insoluble surfactant-matrix material, phospholipase-D, racemic or enantiomerically-pure serine, amino acid, and/or a water-soluble, surfactant-forming amine and salts in a pH-buffered aqueous solution, wherein said step of processing is performed in a single-phase reaction environment, to produce phosphatides, or the salts thereof, having a structural fatty-acid chain derived from said at least one raw material lecithin.
