| Abstract: | The effects of ultrasonic treatment,extrusion,repeated freeze-thaw and high-pressure homogenization on the extraction rate of microalgae oil and fatty acids inextracted oil were studied to explore the best method of breaking the wall.The results showed:Microalgae oil was extracted with mixed solvents-hexane:ethanol=10∶3,and the oil yield was 26.19%±0.25%,22.46%±0.17%,25.56%±0.12%and 24.89%±0.35%after ultrasonic assisted wall breaking,high pressure homogenization wall breaking,extrusion wall breaking and repeated freeze-thaw wall breaking,respectively.The effects of extrusion and ultrasonic assisted wall breaking were better.The microalgae oil were detected and analyzed by gas chromatography Palmitoleic acid is rich in essential fatty acids,linoleic acid and linolenic acid content is about 10%,which contains 50%saturated fatty acids,more than 40%monounsaturated fatty acids and 10%polyunsaturated fatty acids,even carbon fatty acids accounted for more than 80%. |
| Keywords: | microalgae wall breaking oil fatty acid |
