Supercritical fluid

A supercritical fluid (SCF) is any substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not exist.It can effuse through solids like a gas, and dissolve materials like a liquid. In addition, close to the critical point, small changes in pressure or temperature result in large changes in density, allowing many properties of a supercritical

Recent advances in extraction of nutraceuticals from

Various novel techniques including ultrasound-assisted extraction, microwave-assisted extraction, supercritical fluid extraction, and accelerated solvent extraction have been developed for the extraction of nutraceuticals from plants in order to shorten the extraction time, decrease the solvent consumption, increase the extraction yield, and enhance the quality of extracts.

Produzione. I vinaccioli contengono olio in ragione del 10-20%, percentuale che varia con la cultivar.I vinaccioli sono normalmente ricavati dalle vinacce come sottoprodotto della produzione vitivinicola. È necessaria una accurata e veloce fase di essiccamento per produrre un olio con buone caratteristiche organolettiche e un buon contenuto di polifenoli, se così non avviene i microrganismi
