Lipid extraction from plant and muscle tissues using superceitical CO_2

摘要

Different celland tissue structures of various biological materials as well as their moisture content play an important role in the extraction fo lipids with supercritical carbon dioxide (SC-CO_2). All biological matter is made up of water, proteins, lipids, carbohydrates and inorganic salts. Hundreds of components are organized within the cell structure where they interact with each other in various ways. When such a complicated system is placed in a high-pressure environment with the objective of extracting specific components using a supercritical solvent, the complexity of the system increases dramatically. Our understanding of the ocmponent interactions during supercritical fluid extraction is quite limited. Thus, structure of the starting materials and location of the components of interest need to be examined to have a better understanding of the component interactions and how they affect extractionkinetics.
