Abstract
Accelerated solvent extraction (ASE) was used for a rapid and simple extraction of propylenchlorohydrin (PCH) residue in hydroxylpropyl modified starch. The effects of temperature, pressure and extraction solvent on the extraction efficiency were investigated to find the optimal condition of ASE. The optimal conditions for PCH extraction in hydroxylpropyl modified starch were static time of 50 min, purge time of 300 sec, heating time of 5min, temperature of 12$0^{\circ}C$, pressure of 2500 psi, flush (%) with 100 volumes, and ethylacetate as an extraction solvent. The recovery (96.1%) of this method was higher than that (76.4%) of Code of Food Additive. Therefore, the ASE was a good method in both aspects of efficiency and effectiveness.
