Abstract

Soybean oil and olive oil were investigated as continuous co-solvents for supercritical carbon dioxide (SC-CO(2)) extraction of astaxanthin from Haematococcus pluvialis. Without co-solvents, only 25.40+/-0.79% efficiency was achieved with SC-CO(2) extraction at 70 degrees C and 40 MPa at a continuous flow rate of 3 mL min(-1) for 5h. In the presence of soybean oil or olive oil as a co-solvent, the extraction efficiency was enhanced, with the most appropriate level of soybean oil in the solvent mixture being 10% by volume. At this concentration and the above extraction conditions, the highest extraction efficiency of 36.36+/-0.79% was obtained for soybean oil, a 30% increase in extraction efficiency compared with SC-CO(2) extraction without soybean oil, whereas the 10% olive oil increased the extraction efficiency further to 51.03+/-1.08%, which was comparable to that obtained using ethanol as co-solvent.

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.
