After eating garlic, the residual smell in the mouth mainly comes from chopped garlic, which is an organic sulfide component in garlic-a capsaicin called "propylene sulfide". "Propylene sulfide" can penetrate the surface of oral cell membrane and make its taste stay in the oral cavity for a long time. It was found that after eating a spoonful of garlic juice (about equivalent to a clove of garlic), the garlic smell would stay in the human body for 16 hours. Therefore, usually after eating garlic, even after two or three days, our mouths and bodies will still smell of garlic. Some people will try chewing gum or drinking tea to relieve their breath, but they still can't completely get rid of the garlic smell. Here, I would like to introduce a good method to you: after eating garlic, drink a glass of milk, and the protein in the milk will react with garlic, which can effectively remove the garlic flavor. However, when drinking milk, you should pay attention to chewing slowly, let the milk stay in your mouth for a while, and it is better to drink warm milk, which will be better. In addition, there are some simple and easy ways to reduce the smell of garlic. For example, after eating garlic, chew some foods with high protein content, such as peanuts, walnuts or almonds, and combine the irritating element "propylene sulfide" in garlic with protein to remove the garlic smell in the mouth; Gargling with vinegar or wine will also reduce the taste of garlic.
