Investigation of Process Variables in Supercritical Carbon Dioxide Extraction of Soybeans using a Teledyne Isco Syringe Pump and Extraction Module
12 Jul 2015Soybean oil is one of the most widely used plant oils today. Most soybean oil is extracted using hexane solvent extraction; while being fast and efficient, this has several disadvantages. Supercritical CO2 offers an attractive alternative for extraction with smaller environmental and health impacts because it is nontoxic, non-flammable, cheap, and readily removed from the extract. This application note aims to optimize process conditions to reduce the energy cost to extract soybeans, including the amount of supercritical CO2, using Teledyne Isco’s 260D syringe pump and SFX-2-10 extraction module.

Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.Supercritical Fluid ChromatographySupercritical Fluid Chromatography (SFC) is used for the rapid separation and analysis of complex mixtures. SFC systems require injectors, pumps, columns, ovens and detectors. The SFC retention method uses a supercritical fluid, usually CO2. There are a number of different SFC detector types including UV / VIs, ECD, mass spectrometry and fluorescence.Pressure ControlLaboratory SafetyLaboratory safety is essential to the effective operation of all laboratories and is required to minimize the risk of harm during experiments. Guidelines, regulations, and equipment should be available in all laboratories to ensure that the working environment is safe and secure.Solvent ReductionCarbon DioxideExtraction Module
