Supercritical fluid extractions in biotechnology.
Over the past decade, supercritical fluid (SCF) extraction has been shown to deserve consideration as an alternative to liquid-liquid extraction or distillation. Most current commercial applications of SCF extraction involve biologically produced materials; the technique may be particularly relevant to extraction of biological compounds in cases where there is a requirement for low-temperature processing, high mass-transfer rates and negligible carry over of solvent into the final product. New advances, in which extraction is combined with reaction or crystallization steps, may further increase the attractiveness of SCFs in the bioprocessing industries.
