Extraction is the initial and significant step in purifying active ingredients from plant materials. Traditional methods like heat reflux and cold extraction are widely based on an appropriate selection of solvents, agitation and rate of mass transfer to increase the chemical solubility. Thus, traditional methods require long extraction time with low extraction yield and high energy consumption. Ultra High pressure-assisted extraction (UHPE), works under very high pressure ranging from 100 to 800 MPa and has been recognized as an environment-friendly technology by the Food and Drug Administration. Application of ultra high pressure can increase the rate of mass transfer, solvent permeability and secondary metabolite diffusion in plant cells. Recent studies have confirmed that the HPE technique could significantly shorten the extraction time and obtain higher extraction yield. In addition, the antioxidant, antityrosinase and anticancer activities of UHPE are significantly higher than conventional extraction. This webinar presentation demonstrates the application of the high pressure-assisted extraction, using litchi and longan fruits as the examples.Speaker 1: K.
