The invention relates to a phospholipid and a preparation method therefor. The preparation method for the plastic phospholipid, disclosed by the invention, is characterized by comprising the following steps: (1) dissolving a raw material phospholipid in an organic solvent, of which a hydrophobic constant log P is 3 or more; (2) adding water in the organic solvent; (3) mixing the organic solvent and the water, carrying out layering, and collecting an organic phase; and (4) drying the organic phase obtained in the step (3). The plastic phospholipid prepared by the method is low in acetone insoluble content and can be used for obviously improving the texture and chewiness of products when the plastic phospholipid is applied to chew food.
