Abstract
|
|
|
|
The volatile organic compounds(VOCs) emitted from raw garlic and Kimchee were analyzed with thermal desorption or purge ＆ trap/gas chromatography/mass selective detection method. Very offensive compounds such as methyl allyl sulfide, dimethyl sulfide, dimethyl disulfide, diallyl sulfide, methyl allyl disulfide, diallyl disulfide and dimethyl trisulfide were detected, and among them, dimethyl disulfide and dimethyl trisulfide were confirmed to be generated during the precocity of Kimchee or emitted from the stuff of Kimchee other than the garlic. Malodorous compounds emitted from the garlic or Kimchee were detected in the breath of a Korean and the refregirator keeping Kimchee. It was confirmed that the disufides emitted from the garlic or Kimchee were major components of offensive odor in the alveolar air and the refregirator. It was clarfied that heat process is very effective to reduce odorous VOCs in garlic or Kimchee.
