Inhibitory effect of ethanol diffusion assuming breath after drinking by acetic acid bacterial enzymes

One of the problems from drinking alcohol is that it can cause bad breath, and the present methods to reduce the unpleasant odor do not have a direct effect on the components that cause it. Therefore, a novel more effective method for reducing bad breath is required. We investigated the effect of acetic acid bacterial enzymes on bad breath, as they are known to convert alcohols and aldehydes into carboxylic acids. Therefore, we determined that the odor concentration of expiration depended on ethanol by examining the influence of the ratio of ethanol and other odor components on the odor concentration. Furthermore, it was suggested that the diffusion of bad breath could be suppressed by reducing the ethanol concentration in expiration. These results indicate that acetic acid bacterial enzymes can reduce both the strength and diffusion of bad breath. Therefore, acetic acid bacterial enzymes could potentially be developed into new products that can effectively reduce unpleasant bad breath after drinking alcohol.
