SEPARATION OF CONSTITUENTS OF FISH-OIL USING SUPERCRITICAL FLUIDS - AREVIEW OF EXPERIMENTAL SOLUBILITY, EXTRACTION, AND CHROMATOGRAPHIC DATA

The use of supercritical fluids, especially carbon dioxide, in separat ion of fish oil and derived compounds has increased the last decade du e to the expected advantages of supercritical separation processes. In pursuit of the design of supercritical fluid separation processes, ph ase equilibria and pilot plant data are essential. In this paper we pr esent a survey of literature references of experimental phase equilibr ia and solubility data on binary and multicomponent systems of supercr itical fluids and fish oil or derived compounds, as well as experiment al data on supercritical fluid extraction (SFE) and supercritical flui d chromatography (SFC). The fish oil related compounds include triglyc erides, free fatty acids, fatty acid methyl and ethyl esters, choleste rol, alpha-tocopherol, phospholipids, squalene etc. The list of refere nces include the experimental pressure and temperature ranges, the num ber of data points/experiments, and some remarks to the kind of measur ements performed and components involved. The literature retrieval inc ludes references to the end of 1992 and a few from 1993.
