  • High pressure extraction and formulation processes [Elektronski vir]
    Knez Marevci, Maša ...
    Extraction of substances from plant materials, chromatographic separation of components and their formulation in products with specific properties is at the moment one of the very promising ... applications of supercritical fluids. One of the most important advantages of use of supercritical fluids is selective extraction of components or fractionation of total extracts. This is possible by use of different gases for isolation/fractionation of components and/or changing process parameters. The limitation of further application of extracts obtained by high pressure technology is in the price of the product, which is in comparison with conventionally obtained products relatively high. The legal limitations of solvent residues and solvents (for products for use in human applications) and isolation/fractionation of special components from total extracts in combination with different formulation and sterilization processes will increase the use of dense gases for extraction applications. Applying supercritical fluids for formulation of products, e.g. for formation of solids with unique properties and composites with special characteristics for the use in different applications are studied intensively. In our presentation fundamentals (phase equilibrium data for some systems solid/SCF), design and applications of processes for extraction of components from solid mixtures and formulation of products using supercritical fluids is presented. For above mentioned processes recent advances and trends of developments are presented.
