Abstract: Disclosed are stable PS preparations, in powder, liquid and dispersion forms, as well as methods of producing thereof. Most importantly, the stable PS preparations are particularly devoid of residual phospholipase D activity, and the methods of eliminating such activity are also described herein. Lastly, uses of these PS preparations in nutraceuticals or as active agents of pharmaceutical compositions are also provided herein.

Abstract: A new enzymatic process for preparing 1,2-diacylated phospholipids using an enzyme preparation possessing phospholipase activity towards acylation at the sn-1 and sn-2 sites in a microaqueous reaction system. More particularly, the 1,2-diacyl-phospholipids produced according to the esterification/transesterification process are obtainable in high yield and purity and carry identical desired carboxylic acid, preferably fatty acid, acyl groups at the sn-1 and sn-2 positions. The process involves esterification/transesterification (acylation) of a glycerophospholipid, preferably glycerophosphoryl choline (GPC) with a desired carboxylic acid, preferably fatty acid, or their derivatives in the presence of the above mentioned appropriate enzyme preparation.
