Regular coffee can prevent halitosis, which is also well studied in the science of halitosis.

The science of bad breath is also well studied, with the advent of mouthwash, breath fresheners and chewing gum. Now there is a new study, that is, we now often drink coffee, coffee contains substances to inhibit bad breath.

Coffee contains substances that inhibit bad breath and may be used in mouthwash, breath fresheners or gum to keep your breath fresh, according to a new study by Israeli scientists. Tone expert Mel, Tel Aviv University, Israel. Professor Rosenberg stumbled upon this magical effect of coffee in his experiment. Previously, it was generally believed that drinking coffee would make you have a bad breath. In fact, when coffee is mixed with milk, it dehydrates inside the mouth and ferments to produce odorous substances.

Rosenberg's team selected two Israeli-made coffee and a Nestle instant coffee and put them in a glass tube filled with saliva. They initially hoped the experiment would prove that coffee mixed with saliva produces foul-smelling gases.

Scientists believe that bad breath is inevitable, and even the healthiest bodies wake up in the morning with bad breath. The tongue and alveoli inside the mouth are the "paradise" of dental plaque. This kind of bacteria can produce volatile sulfur compounds that make the mouth stink. If you eat strong foods such as onions and garlic, bad breath will last for a long time. Because the blood will absorb these food ingredients, then enter the lungs, and then exhale.

Rosenberg plans to isolate the magic substance in coffee that suppresses bad breath, believing it can inhibit the formation of dental plaque and block the occurrence of bad breath at the source. It may replace mint, which can only cover breath, and become the basic ingredient of a new generation of mouthwash, breath freshener and chewing gum.

Traditional mouthwash and gum can only be temporarily covered but can not completely eliminate bad breath.
