Omega 3, 6, and 9 fatty acids were separated and enriched successfully from the by-products of Vietnamese Basa fish processing by the deep eutectic solvent. The total amounts of omega fatty acids were about 57% in the raw material, and they were amounted to 91% after the first separation by DES. The optimal mass ratio is 20 g methyl ester with 200 g methanol and 15–20 g DES. Moreover, the ionic liquid-DES was successfully synthesized with the molar ratio of choline chloride/urea of 1 : 1 and 2
