NOVELTY - Silkworm pupa waste is dried, crushed, and obtained powder is subjected to ultrasonic-assisted organic solvent extraction to obtain crude silkworm pupa oil. Modified graphene oxide is added, adsorption treatment is carried out at 10-60 degrees C for 0.25-5 hours, and filtered to obtain odorless white purified pupa oil. Modified graphene oxide is prepared by heat-treating graphite at 880-920 degrees C by Hummers method. The crude silkworm pupa oil has solid-liquid ratio of 0.1-0.6 g:10 ml. USE - Extraction of odorless white silkworm pupa oil from silkworm pupa waste (claimed). ADVANTAGE - The method enables rapid extraction of odorless white silkworm pupa oil having excellent decolorizing effect, with high purity without damaging active ingredients, by a simple process.
