마늘장아찌의 휘발성 함황화합물

Solvent extract of homogenates of fresh garlic or pickled garlic was subjected to GC-MS analysis, which showed 30 volatile sulfur compounds for fresh garlic and 20 compounds for processed one. Maior sulfur compounds from fresh garlic extract were identified to be 3-vinyl-[4H]-1,2-dithiin, diallyl disulfide,3,4-dimethylthiophene and methyl allyl sulfide. Meanwhile, the number of volatile compounds from pickled garlic decreased gradually during storage. Diallyl disulfide, methyl allyl trisulfide and diallyl trisulfide were major volatile sulfur compounds from pickled garlic stored for 50 days. It is appeared that the amount of trisulfides in pickled garlic increased gradually during storage, in contrast to the amount of dithiins and monosulfides in pickled garlic decreased.
