After eating mints for so many years, why is there a hole in the middle

Candy should be every child's favorite snack. Every supermarket has candy more or less. I still remember watching a movie "Charlie and the Chocolate Factory" when I was a child. The film mainly talks about a kind of hard candy that can never be eaten. At that time, I thought it was a human fantasy. I didn't expect that this endless candy was produced in recent years and can be eaten for a long time. But today we are not talking about this super hard candy, but that we are very common.

Snacks are now served in many public places, and this mint is the most common one. For example, a small fruit bowl will be set up in the lobby of the hotel for people to take it for free. This kind of mint is not only delicious, but also can remove the peculiar smell in the mouth, and the cool feeling is quite good. Eating this mint in summer will make me feel chilly. However, there is a question that has been bothering me for a long time, that is, why use mint.

I don't know if my friends after 90 have any impression. When we were young, this kind of candy was not hollow, but solid candy pieces. But later, the candy of a candy company was eaten by children, stuck in the throat, and it was difficult to breathe. In order to prevent this from happening again, the candy factory decided to dig a hole in the middle of the candy, so that even if it was stuck, it could still breathe and avoid serious accidents when eating candy.

Maybe you haven't found that mints with holes are cooler than mints without holes. The sweetness of candy itself is actually proportional to the dissolution rate. The faster the dissolution, the sweeter the candy will be. So according to scientific research, mints with holes are better than mints without holes, especially mints themselves have a cool feeling. Peppermint with holes will increase the contact area with air, giving people a cooler feeling.

Although mints are good, don't be greedy. Although we usually feel refreshed when eating mints, it can also remove the odor in our mouth. Eating mints for a long time will stimulate our oral mucosa and cause other diseases in our mouth. Moreover, mints are also sugar, which is easy to cause hyperglycemia and is not good for our health.
