Abstract: Disclosed is a method of preparing krill oil. A method of preparing krill oil may include providing a dried krill powder; obtaining an extract after adding spirits of wine to the dried krill powder; obtaining a passing solution from which salt and cholesterol are removed by passing the extract through a column; obtaining a krill concentrate by decompression-concentrating the passing solution; and obtaining krill oil by stationarily positioning a mixture obtained by adding spirits of wine to the krill concentrate, layer-separating the stationarily positioned mixture, extracting a supernatant of the layer-separated mixture, and concentrating the extracted supernatant.
