Theoretical screening methods are based on a thermodynamic
description of the investigated system. Here, the
selection of solvents is based upon the solubility parameters
of solvent–solute systems. The useful prediction
method proposed by Yamamoto was applied to calculate
HSPs of alternatives solvents and terpenes in blackcurrant
extracts (Table 1). Two dimensional (2D) graph of dp versus
dh parameters (Fig. 3) shows the different aromas in
blackcurrant and the different alternative solvents according
to Hansen’s parameters. The influence of the structure
of the molecule on polarity is presented. In fact, terpenes
and n-hexane display similar HSP values, whereas
oxygenated compounds have different HSPs due to their
hydroxyl group or carboxyl group, which resulted in a
higher dh value. The calculated HSP values were close to
those of some alternative solvents, which demonstrated
