Researchers at the Virginia Tech (Blacksburg, Virginia) Department of Chemistry have used supercritical fluid extraction with methanol-modified carbon dioxide to separate polar lipid fractions from crude soybean lecithin.
Researchers at the Virginia Tech (Blacksburg, Virginia) Department of Chemistry have used supercritical fluid extraction with methanol-modified carbon dioxide to separate polar lipid fractions from crude soybean lecithin. Pure carbon dioxide was used to remove the neutral lipids. The phosphatidyl choline-enriched fraction of the soybean lecithin was the target of this extraction. They isolated and identified six components in the crude soybean lecithin extract.
Dispersive Liquid-Liquid Microextraction: A Review and Roundup of Green Sample Prep Advancements
May 15th 2024The still relatively new technique has distinct advantages, but a few of those benefits make it incompatible with some of the currently accepted principles of green sample preparation.
