Extraction of Oil from Papaya Seed by Supercritical CO_2 Analysis and Its Composition

Lin Hai

Abstract

To efficient extraction of oil from papaya seed.Supercritical CO2 technology was used to extraction of oil from papaya seed and the composition of papaya seed oil were analyzed by GC-MS.The results showed that the best extraction conditions were:extraction pressure 35 MPa,extraction temperature 35℃,extraction time 130 min and CO2 flow rate 15 kg/h.The yield of oil was 21.8%.Total 5 kinds fatty acid were found in oil.Among of it,the content of oleic acid was 65.2%.
