Check if you can 'kiss it'

Many people often breathe into their palms to check if they are ready for a job interview, or even for a date with a 'special person'. Researchers have developed a pocket breath test device that can detect breaths that are offensive by bacteria.

You just need to lightly brush some saliva on a small window of the OkayToKiss device. The blue result appears to remind users to brush their teeth, while the results in the signal are safe to carry out 'intimate' acts by mouth.

Mel Rosenberg, a Tel Aviv University scientist in Israel, said: 'OkayToKiss will turn green if the user has oral enzymes produced by positive gram bacteria. The appearance of these enzymes means that your mouth is busy creating bacteria and may have unpleasant breaths. '

The OkayToKiss device is about the size of a chewing gum, and is easy to put in a pocket or purse. Researchers say it encourages oral cleaning such as brushing teeth or mouthwash, but it also offers more social benefits and a sense of comfort before starting to act "intimate" with people. to love.

Previous scientists believe that a type of bacteria, called a gram, is the cause of unpleasant breathing. However, Rosenberg and Dr. Nir Sterer at Tel Aviv University found that gram-positive bacteria are also responsible for this unpleasant breath.

Scientists have implanted this bacterium in biofilms and found that gram-positive bacteria produce enzymes capable of removing sugar components in proteins.

Details of this discovery, see the March issue of the Journal of Breath Research. Rosenberg is one of the two main editors of this magazine.

Biological indicators that appear in OkayToKiss also appear in many other diagnostic devices, such as pregnancy testing or controlling glucose levels in people with diabetes.

Rosenberg's previous discovery also led to two-stage mouthwash becoming popular in the United Kingdom, Israel and many other places.

Rosenberg's forthcoming book 'Protect Your Breath' summarizes 20 years of studying his breath.
