Claim Text:
1. A method for producing a composition containing 2-acyl-lysophosphatidylserine, the method consisting of: (a) obtaining a composition containing phosphatidylserine by allowing phospholipase D to act on a raw material containing phosphatidylcholine in the presence of serine to produce phosphatidylserine; and (b) treating the composition containing phosphatidylserine obtained in (a) with phospholipase A1 in the presence of at least one selected from each of (I), (II), and (III): (I) one or more salts selected from the group consisting of sulfate salts, phosphate salts, nitrate salts, citrate salts, and tartarate salts of monovalent cations, (II) a gum selected from the group consisting of gum arabic present in a concentration of 1 to 10%, xanthum gum present in a concentration of 0.1%, tamarind gum present in a concentration of 1 to 3%, tara gum present in a concentration of 0.5% and locust bean gum present in a concentration of 1%, and (III) an emulsifier to obtain a composition containing 2-acyl lysophosphatidylserine containing 26% to 51% by mass of a lysophospholipid per solid content.
