in vivo quantification of the major volatiles in the breath after garlic ingestion
since the metabolism of garlic inside the body is difference from the chemical reaction that occur outside the body , and milk shows a significant deodorizing effect against all analyzed volatiles in the in vivo test, the effect of milk on the deodorization of the garlic volatiles in breath after garlic ingestion was also investigated . the concentration of diallyl disulfide , allyl methyl disulfide were measured in the mouth- and nose-space for 60 min after garlic ingestion. in the first 30 min after ingestion , diallyl disulfide and allyl mercaptan were the 2 major volatile compound in the mouth-space whereas allyl methyl sulfide and allyl methyl disulfide were minor volatiles . methyl mercaptan was present at a lower level than the detection limit of the SIFT-MS . allyl mercaptan and diallyl disulfide have been identified as the major volatiles found in breath immediately after ingestion of raw garlic in many studies.
