Food Processing Using Supercritical Fluids

摘要

The chapter contains a limited overview of SCF based technologies which offer important advantages over organic solvent technology, such as ecological friendliness and ease of product fractionation. Extraction of hop components, decaffeination of tea and coffee are the largest scale extraction processes using sub- or supercritical solvents, which are realized on industrial scale. Several industrial plants are in operation also for extraction of spices for food industry and natural substances for use in cosmetics. There are less industrial units for separation of components from liquid mixtures using sub- or supercritical fluids.
