the effect of milk and milk component on the deodorization of diallyl disulfide, allyl methyl disulfide , allyl mercaptan , allyl methyl sulfide ,and methyl mercaptan in the headspace of garlic as well as in the mouth and nose space after garlic ingestion was investigated using select ion flow tube-mass spectrometry. fat free and whole milk significantly reduced the head-, mouth-, and nose-space concentration of all volatiles. water was the major component in milk reponsible for the deodorization of volatiles. due to its higher fat content, whole milk was more effective than fat-free milk in the deodorization of the more hydrophobic volatiles diallyl disulfide and allyl methyl disulfide. milk was more effective than water and 10 % sodium caseinate in the deodorization of allyl methyl sulfide , a persistent garlic odor , in the mouth after garlic ingestion . addition of milk to garlic before ingestion had a higher deodorizing effect on the volatiles in the mouth than drinking milk after consuming garlic.
