For the extraction of oil from microalgae, which was recognised as an important renewable source of bioactive lipids, supercritical CO2 is regarded with interest being safer than hexane and offering a negligible environmental impact, short extraction time and petroleum-free final product. A mathematical model, able to describe the kinetics of a supercritical fluid extraction (SFE) process, was applied to recovery of oil from cyanobacterium Spirulina (Arthrospira) Platensis, characterised by a particularly high content in -linolenic acid (C18:3-6). In this paper, we examine the kinetics of the SFE and the effect of operating conditions on extraction yield and fatty acid composition of liquid extracts.
