Abstract
During the last 20 years there has been a clear shift from standard “18/12” fish oils—where “18” stands for 18% eicosapentaenoic acid (EPA) and “12” stands for 12% docosahexaenoic acid (DHA)—to concentrated “omega-3 oils.” It was a gradual process over most of the years, but lately the demand for high concentrated omega-3 oils has increased dramatically. A first step was achieved by eliminating most saturated and mono-unsaturated fatty acids and in this way reaching EPA + DHA concentrations of 50–55%. This concentrate became very popular in the past couple of years and is often referred to as the “33/22.” Then, due to the commercial success of Lovaza (Omacor), the demand for EPA + DHA concentrates reaching 85% increased significantly and lately a clear trend to highly concentrated EPA (EPA 96%) is observed, most likely based on the soon-to-be-commercialized Amarin drug AMR101. Today there are only a handful of companies worldwide that are able to produce EPA and/or DHA products with more than 95% purity, but this will change in the near future owing to the growing demand for such products.
