Because of the todays pursuit for health products the production of vegetable extracts by supercritical fluid extraction is an area of industrial interest.Nonetheless,the relatively high investment costs associated with high-pressure processes are responsible for the elimination of this technology at the very early stages of process design,that is,during the selection of the extraction process.In order to avoid this,a preliminary analysis of the cost of manufacturing must be done with a minimum of experimental information.Thus,a simple method to estimate the cost of manufacturing of extracts by supercritical fluid technology is needed.In this talk,we will present a rapid method to estimate the cost of manufacturing of extracts using supercritical fluid extraction that may accelerate the adoption of SFE as an alternative among the various extraction techniques.
