Supercritical fluid extraction of 5-hydroxymethyl-2-furaldehyde from raisins.

An extraction method based on supercritical CO(2) has been developed for the analysis of 5-hydroxymethyl-2-furaldehyde in raisins. To optimize extraction variables, a fractional factorial experimental design was applied. Six extraction variables were optimized. The organic modifier used for increasing the extraction fluid solvating power was the most… CONTINUE READING
