Subcritical fluid extraction is performed at lower temperatures and pressures than those employed in supercritical fluid extraction.It is an excellent extraction that has some advantages such as lower operating temperature and pressures,shorter extraction time,environmental compatibility,good selectivity,one step from the extraction to the separation and avoidance of residual solvents.Subcritical fluid extraction based processes are applied to a wide variety of areas,including forestry products,essential oil,special plants and Chinese herbal medicine oil,natural spices,removal of pesticide residues.The subcritical extraction equipment has been very mature and the extraction capability ranged from 1 to 100 T/D.In this paper,the objective was to review the subcritical fluid extraction process and the application of subcritical fluid extraction on forestry products.
