Zhang, Mengna published the artcileEffect of purification methods on functional properties of sardine oil ethyl esters, Safety of Ethyl octanoate, the main research area is sardine oil ethyl ester purification method functional property.
In this study, four methods including urea complexation (UC), mol. distillation (MD), low-temperature crystallization (LTC), and Ag+ bonded to mercaptopropyl silica gel column chromatog. (AgMSG-CC) were adopted to purify eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) from sardine oil Et esters (SOEEs). These methods were systematically compared in terms of physicochem. properties, fatty acid (FA) compositions, and volatile flavor compounds to evaluate the performance and find the superior among them. The AgMSG-CC method was superior in enhancing iodine value (IV) and reducing peroxide value (PV), enriching EPA and DHA from 31.63% to 92.19% and removing undesirable volatiles. Its mild exptl. conditions could avoid the degradation and geometrical isomerization of lipids, and the packed AgMSG column could be reused. Multivariate data anal. was applied to provide an integrated and holistic view of correlation coefficients between the samples and FA species. The results supported the critical role of AgMSG-CC method in purifying EPA and DHA. Finally, this method was validated to be accurate and sensitive in the purification of EPA and DHA from SOEEs. Practical applications : High quality of fish oil is related to its high content of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) and friendly aroma. However, enrichment methods about purifying fish oil affect the percentages of EPA and DHA, physicochem. indexes and the volatile flavor. In this study, the results demonstrated that Ag+ bonded to mercaptopropyl silica gel column chromatog. was the most effective to purify EPA and DHA as well as remove the undesirable odor volatiles.
