The invention discloses a novel method for extracting and separating euphausia superba oil. The krill meal contains substances such as krill phospholipid, krill oil, fatty acid, astaxanthin, small molecule polypeptide, organic arsenic, basic nitrogen with heavy fishy smell and the like. The process of the substances or impurities from the shrimp powder to the solvent belongs to diffusion control, namely the lower the content in the solvent is, the faster the diffusion is, and the minimum amount of the needed solvent is, the higher the extraction yield is. Therefore, a percolation method is most suitable for extracting the shrimp oil, the shrimp powder is always in contact with a fresh solvent, and the maximum concentration difference, namely the maximum diffusion power, is kept. The percolation process is similar to the chromatography process, different substances are different in sequence when eluted due to different molecular structures, and the krill phospholipid and the oil are enriched respectively.

And the yield is 1-2% higher than that of a stirring method. If a product containing 56% of phospholipid needs to be produced, extraction can be completed only by absolute ethyl alcohol with the volume 2-3 times that of the mass of the shrimp meal. In the percolation process, time difference exists between extraction (or elution) of the krill phospholipid and extraction (or elution) of the krill oil, and krill oil products with different phospholipid contents can be conveniently obtained by utilizing the characteristic.
