  • Patent number: 7695944
    Abstract: A method for producing a phospholipid using transphosphatidylation, which comprises homogenizing a mixture of a raw material phospholipid, a hydroxyl-containing acceptor, phospholipase D, and water in the absence of an organic solvent to obtain a homogenized mixture; and subjecting the homogenized mixture to a transphosphatidylation reaction at 15° C. to 65° C. The homogenized mixture has a lamellar lyotropic liquid crystal structure. An objective phospholipid can be obtained from the homogenized mixture through transphosphatidylation without using an organic solvent or calcium.
    Type: Grant
