Abstract:
      Using refined sardine oil ethyl ester(EPA content(15.41±0.13)%, DHA content(8.00±003)%)as raw material, the effects of urea-ester ratio, inclusion temperature, ethanol-urea ratio and inclusion time on the EPA and DHA enrichment process were studied by single factor experiment, and the response surface methodology was used to optimize the urea inclusion enrichment process. The results showed that the optimal process conditions were obtained as follows: urea-ester ratio 3.5∶?1, inclusion temperature 0?℃, ethanol- urea ratio 2.6∶?1, and inclusion time 1.2 h. Under these conditions, the total content of EPA and DHA was(78.12±0.12)%(EPA content(53.35±0.10)%, DHA content(24.77±0.02)%), which was consistent with the theoretical value of 78.17%.
