“…A previous study revealed that extraction of oil from oleaginous fungus, Mortierella alpine, using hexane had a higher percentage of oil extracted than the SC-CO 2 method 15 . Hexane also differs from CO 2 because it is non-selective for triglycerides, causing it to extract almost all available fatty acids, pigments, phospholipids and unsaponifiable substances along with triglycerides 16 .…”

Supercritical CO 2 (SC-CO 2) was used to extract dabai oil. Total phenolic content, total flavonoid content, DPPH radical scavenging assay, and gas chromatography analysis were performed to determine the antioxidant properties of SC-CO 2-extracted dabai oil and to compare with hexane-extracted dabai oil. The total phenolic content of SC-CO 2-extracted oil was slightly higher than hexane-extracted oil, whereas the total flavonoid content of SC-CO 2extracted dabai oil was four times lower than the hexane-extracted oil. The percentage of radical scavenging activity for SC-CO 2-extracted oil was 0.71%, but the hexane-extracted oil had a higher radical scavenging activity of 3%. Analysed using gas chromatography, SC-CO 2-extracted oil had lower total saturated fatty acids than the hexane-extracted oil.

“…The percentage of oil (51%) obtained by hexane extraction was almost twice as high as the SC-CO 2 extraction (23%). Unlike the SC-CO 2 extraction method, the lipid soluble substances together with triacylglycerols are basically more soluble in hexane 15 .…”

The extraction of lipids from freeze-dried Mortierella species using supercritical fluids (Sako et al, 1989;Sakaki et al, 1990) and using CO 2 (Dalai et al, 2011;Nisha et al, 2012) and organic solvents has been previously reported. The batch extraction of water from a bed of MA with DME takes place under almost steady state conditions, as shown in Fig.…”

Supercritical fluids are increasingly being used and promoted at a laboratory and pilot scale to produce high value, natural bioactives from biologically based raw materials. Supercritical CO₂ is overwhelmingly the solvent of choice for these operations, but is largely limited to the processing of dry raw materials and the extraction of low polarity, low molecular weight compounds. The use of co-solvents and the use of alternative ânear-criticalâ extraction fluids such as dimethyl ether show potential to mitigate these limitations. Commercialisation of new supercritical extraction processes has arguably been limited because the supercritical extraction process has been developed in isolation of other processing steps necessary to achieve a successful product. This study reviews recent developments in integrated processing that incorporate the use of supercritical fluids for bioseparations and in particular process schemes that produce high value natural bioactives. Integrated processes include prior operation (fermentation, extraction, enzyme pre-treatment, physical fractionation or size reduction) followed by supercritical extraction or fractionation and processes in which operations are carried out in situ in supercritical fluids (supercritical chromatography, enzymatic conversion, precipitation and coating of solutes). The use of co-solvents and alternative extraction solvents in these processes is discussed. Prospects for future developments are also discussed

“…These methods were developed to extract lipids from fishes or vegetables. Since then, they have been modified and adapted for microbial lipids extraction [39,40,41,42]. The final processing of oils (microbial or natural) involves purification or refining and modification (Table 3) [7] in order to stabilize the crude oil [43].…”
