The tradition of blowing out the candles on the birthday cake is still busy today. Who knows who did it first, which is clearly a celebration is considered less fun if not a tradition of inflatable candles.
But a surprising fact was revealed from research conducted by scientists at Clemson University, South Carolina, USA. According to the results of the study, when candles in the wind, let alone by many people, then the movement of thousands of bacteria from the mouth to the surface of the cake.
Evil bacteria attached to the surface of the birthday cake can reach the amount of 1,400 percent. Reported by Dailymail page, the condition will be more severe if the candle is difficult to go out and you have to blow it many times.
Dr Paul Dawson, the professor in the study, conducted the study for standardized food quality testing. According to Dawson himself found the idea of research topic when his son’s birthday.
“I found the idea of this research from my daughter when we had dinner together,” Dawson told the Daily Mail on Sunday (30/7).
The research method was done by using a frosting medium in a piece of foil, on which was placed a candle.
The media is then blown by people who previously had been eating food and doing other normal things. Thus the salivary glands have worked and the bacteria in the mouth begin to active.
After blowing the candle, the researchers calculate the amount of bacteria by diluting the frosting with sterile water. Water then placed in the container, then see the development of bacteria in it.
It is a classic method for counting the number of bacteria in a place. According to the researchers, the method was valid to conduct research and publish the results.
Examples of cases of candlelight on the birthday cake can also occur on any object, so it’s good you are alert to the spread of bacteria in public places.
But according to Dawson it should not make you paranoid excessive because bacteria do exist in the environment around humans. You simply maintain health by strengthening the immune system only.
