Super Critical Fluid Extraction of an Essential Oil
Dr. Joyce Easter|
Essential oils are an area of great interest due to the many different uses that have been found for them through different extraction methods. They are used for flavoring food and drinks, as fragrances or perfumes, and some have antibiotic activity. Due to their importance there are new methods of extraction becoming popular as alternatives for steam distillation followed by a liquid-liquid extraction and for solid-liquid extractions. The method that is gaining the most strength is supercritical fluid extraction. This method if utilized properly will allow for the production of less solvent waste with the same efficiency. The goal of this research is to utilize this new method in order to extract clove oil in comparable or better amounts as compared to the traditional methods. The clove oil extracted from steam distillation followed by a liquid-liquid ether extraction gave a pure substance with only one component. This will be compared with a solid-liquid extraction as well as supercritical CO2 extraction in order to see which procedure provides the best yield along with being the most green process.
