ABSTRACT

Solubilization in organic solvents under low pressures (near atmospheric) is one of the most common processes for the recovery of compounds from vegetable matrices. The process considers different operating variables and depends on multiple factors (Teixeira et al., 2014). This chapter focuses mainly on the effect of operational conditions (type of solvent, temperature, pH, and raw material/solvent volume ratio) on polyphenols extraction efciency and the activity of the obtained extracts. Special attention is given to the application of enzymes to enhance the recovery of polyphenols. Finally, examples of scaling up the process are presented, and some suppliers of commercial equipment are mentioned.
