Supercritical fluid extraction of oil from microalga Spirulina (arthrospira) platensis

Andrich, G., Zinnai, A., Nesti, U., Venturi, F.·2006·Acta Alimentaria

Abstract

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.

  • Previous studies on operational variables left GLA extraction efficiency relatively low (25-78%).

    “Previous studies addressed the effect of operational variables (e.g., temperature, pressure, CO2, and co-solvent consumption) on extraction efficiency of GLA [27,28,29,30,32,33,34], but the extraction efficiency remained relatively low (25–78%).”

    The Oil extraction methods (p. 2) tested different temperatures and pressures, and the Conclusions (p. 8) say the extracts had lower GLA content than expected. The paper does not report GLA extraction efficiency of 25–78%, nor does it test co-solvent consumption; its GLA percentages describe fatty-acid composition, not extraction efficiency.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
