| Abstract: |
| The Sacha inchi component was analyzed. The qualities of Sacha inchi oil prepared by ether extraction method, supercritical CO2 extraction method and pressing method were studied. The results showed that the crude fat contents of Sacha inchi and Sacha inchi kernel were 32.88% and 51.86% respectively, and the crude protein content in Sacha inchi kernel was 23.23%. There was no significant difference in iodine value, saponification value and fatty acid composition and content of Sacha inchi oils prepared by the three methods, the contents of unsaturated fatty acids were above 92%, and linoleic acid and linolenic acid were the main components. - Tocopherol and -tocopherol were the main tocopherol in Sacha inchi oil. The contents of tocopherol and sterol in Sacha inchi oils extracted by ether and supercritical CO2 were higher than those in pressed oil, in which the tocopherol content in Sacha inchi oil extracted by supercritical CO2 was higher, and the contents of free sterol and sterol ester in Sacha inchi oil extrected by ether were higher. |
