Author Andy Brunning explains the chemistry behind garlic breath in his new book, Why Does Asparagus Make Your Wee Smell? And it turns out it’s all down to how garlic breaks down.
When you eat garlic, it releases an enzyme called allyl methyl sulfide. This enzyme not only has a very strong scent thanks to its sulphuric compounds, but it can also stick around for up to 24 hours.
Part of the reason allyl methyl sulfide lasts for so long is because of how it’s absorbed into the body. Studies have found that the gas absorbs into the blood and gets transferred to the lungs, where it gets exhaled. It can also be excreted through the pores of the skin – explaining the lingering garlic scent.
This is why chewing gum or rinsing your mouth with water often doesn’t work to get rid of the smell – the garlic scent is sitting in your lungs.
Brunning explains that the best option is lemon juice, which neutralises the enzymes and puts a stop to garlic breath.
