2013-9-11A full evaporation headspace gas chromatographic (HSGC) method is described for rapid determination of ethanol in soy sauce. The results demonstrated that a near-complete mass transfer of ethanol in the soy sauce sample to the vapor phase (headspace) was achieved within 2 min at 105 &C when a very small (≤40 μL) sample was added to a 20-mL headspace sample vial.
