Supercritical Carbon Dioxide Extraction of Spirulina platensis Component and Removing the Stench
Abstract
The chemical component of spirulina was determined by supercritical CO(2) extraction. The protein and essential amino acid contents of spirulina powder were not significantly decreased through supercritical CO(2) extraction, but the contents of total amino acid and lipids were reduced. The spirulina powder had a stench smell before, but not after, supercritical CO(2) extractions. The highest yield rate of lipids was obtained at an extraction pressure of 35 MPa and an extraction time of 4 h. The lipids could be used as additives of health foods containing gamma-linolenic acid.

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%).”

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.
