Summary: The high percentage of polyunsaturated fatty acids of camelina oil (over 50%), which is rich in linolenic acid (37–40%) limits its commercial value and large-scale production. To improve the oil quality and its oxidative stability the methyl esters have been selectively hydrogenated using a non-toxic and non-pyrophoric heterogeneous copper catalyst. Our results showed that both catalysts are able to reduce the linolenic acid content below 1% while selectively increasing the monounsaturated one. Link:
