The aim of the study is to develop a simulation model for the fractionation of fatty acid methyl esters (FAME).by urea complexation. The fatty acids (FAs) were obtained from squid liver and scallop mid-gut, which contain rich in eicosapentaenoic and docosahexaenoic acids well known as health-promoting FAs. FAs can be divided into saturated fatty acid (SFA), monounsaturated fatty acid (MFA), and polyunsaturated fatty acid (PFA) based on the number of double bond in their structure. A fractionation model is proposed and derived from the assumption of the urea-FAMEs complexation reactions, which included equilibrium constants (K) concerned with FAMEs-urea and urea-urea binding. The experiments were conducted at 5 and 28 °C. Different complexation behaviors were observed for SFAME, MFAME, and PFAME. The amount of SFAME captured in the urea inclusion body was larger than MFAME and PFAME. The urea-SFAME and urea-MFAME formation behavior agreed very well with the proposed model, but the urea-PFAME formation behavior showed a large error with the calculation results. The validation experiments showed that the relative error between the experimental data and the model prediction was within 15% for SFAME and MFAME.
