| Supercritical Fluid Extraction (SFE) has been gaining acceptance in a wide range of industrial applications such as fat analysis in the quality control/quality assurance laboratory to larger scale natural product extraction processing. Using the SFT-100 SFE, undergraduate students can investigate and gain experience through use of the technology in numerous industrial related applications. SFE is a replacement technology for the traditional “organic solvent intensive” extraction methods. Traditional QC/QA methods for fat analysis of milk, chocolate, dough and corn chips are both time and labor intensive, and require large amounts of hazardous organic solvents. SFE using CO2 as a solvent is an alternative method for the extraction and isolation of fat content from these products. SFE is an attractive option for the extraction of naturally occurring materials. It is possible to obtain extracts of standardized concentration of active ingredients, products of much higher concentration (higher yields and purity), and quality (with less creation of artifacts), than possible with conventional chemical engineering unit operations such as liquid/liquid extraction, distillation, and mechanical micronization. The flexibility of the SFT-100 SFE unit for the undergraduate teaching laboratory will be demonstrated for fat analysis and process development applications.
