[交流] 【转载】科学家发现喝牛奶可消除大蒜味已有9人参与

美国一项研究发现，吃完大蒜或食用过程中喝牛奶有助于消除口气中令人不悦的蒜味。

大蒜富含镁、硒、维生素B6和维生素C等成分，具有降低血压和胆固醇等功效，有益健康。但吃完大蒜后，那种挥之不去的“蒜香”往往招人厌恶。

来自俄亥俄州立大学食品科学与技术系“维特罗实验室”一份研究报告显示，“蒜香”的主要成分是烯丙硫醇、二烯丙基二硫、甲硫醇等，不少水果、蔬菜和饮料都能消除这些物质的气味，而牛奶去除二烯丙基二硫气味功效最明显。

报告中说，一些富含水分、脂肪的饮料或食品，例如牛奶，可以减轻“蒜香”，且当这些食品和大蒜混在一起吃的时候“除味”效果最佳。

这份发表于美国《食品科学期刊》（Journal of Food Science）的研究报告还提到，水、脱脂牛奶、全脂牛奶和10%的酪蛋白酸钠均有去除蒜味的效果，不过，比起脱脂牛奶，全脂牛奶效果更胜一筹。（来源：新华网）
The effect of milk and milk components on the deodorization of diallyl disulfide (DADS), allyl methyl disulfide (AMDS), allyl mercaptan (AM), allyl methyl sulfide (AMS), and methyl mercaptan (MM) in the headspace of garlic as well as in the mouth- and nose-space after garlic ingestion was investigated using selected ion flow tube-mass spectrometry (SIFT-MS). Fat-free and whole milk significantly reduced the head-, mouth-, and nose-space concentrations of all volatiles. Water was the major component in milk responsible 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.
