  • Patent number: 10561674
    Abstract: The present invention discloses processes for the preparation of phospholipid-enriched dairy products as nutraceuticals for the formulation of functional foods, the processes include the steps of: combining a non-dairy-based PL-containing material, having phosphatidylserine (PS) and/or phosphatidic acid (PA) in the PL-containing material, wherein the PS and/or PA is derived in part from an enzymatically-processed lecithin as a PS-calcium and/or -magnesium salt and/or a PA-calcium and/or-magnesium salt via transphosphatidylation with phospholipase D in the presence of L-serine and a calcium and/or magnesium salt, with water and an oil component to form a paste; removing an excess amount of the water from the paste to form a PL-oil solution; and mixing the PL-oil solution with a dairy component, thereby obtaining a PL-enriched dairy product. Alternatively, the PL-oil solution has a weight-to-weight (w-w) concentration of at least about 0.01% of a residual amount of the water to the PL-containing material.
