Abstract:With the rapid development of food industry in recent years，the demand for edible oil is increasing，so it is particularly important to use efficient extraction methods. Compared with traditional solvent extraction，ultrasound-assisted extraction has high efficiency and consumes short time. This technology uses cavitation effect，mechanical effect，etc.to destroy cell walls，thereby promoting the solvent extraction of lipids. The raw materials for ultrasound-assisted extraction and the corresponding extraction mechanisms were introduced.Further，the performance of ultrasound-assisted extraction of oil and the factors affecting the extraction yield were reviewed. The coupling technology of ultrasound technology in oil extraction was summarized，which provided theoretical support for the application of ultrasound-assisted extraction technology in the production of food lipids.
