Example text

Generally, when the operational pressure is increased, more hydrophilic compounds can also be extracted. If the goal is the extraction of more hydrophilic compounds, then the solvent polarity can be increased by the addition of a polar solvent. The added solvents are named the cosolvents or modifiers [4]. The cosolvent is generally a solvent of high polarity, such as water or ethanol. These two solvents are conveniently selected because both are classified as GRAS (generally recognized as safe).

3 (see Sect. 2). The addition of ca. 6 % of ethanol to ’-pinene allows reducing the distance to the solute and is expected to enhance the solubilising capacities. This effect was observed by Tanzi et al. [35] during the recovery of triglycerides from Chlorella vulgaris for which the addition of a small amount of methanol to chloroform proved to increase the extraction yield. 20 L. Moity et al.
