| contents | Urea Complexation for Docosahexaenoic Acid Enrichment from Crypthecodinium cohnii Oil: Using Water as the Urea Solvent. Sun, Zhaomin Gong, Feifei Liu, Meng Li, Ying Dai, Yaxuan Xiao, Mengying Wang, Junheng Yan, Guangyu Long, Lijun Huang, Haihua Ni, Hui Yu, Lei Urea Docosahexaenoic Acids Water Solvents Temperature Esters Fish Oils Based on the observation that urea, water, and ethyl esters (EE) can form gypsum-like mixtures, this study explored the feasibility of employing water as a solvent for urea in the urea complexation method to enrich n-3 polyunsaturated fatty acids with docosahexaenoic acid (DHA)-containing ethyl esters (DHA- EE) from Crypthecodinium cohnii as the material. Under the conditions of a urea/DHA-EE ratio of 3, a water/DHA-EE ratio of 0.75, a mixing temperature of 65℃, and a cooling temperature of 20℃, a concentrate containing over 90% DHA was achieved. This demonstrated that using water as a solvent for urea, instead of polar organic solvents, is feasible and efficient for enriching DHA in urea complexation process. |
