Experts consider the smell of vanilla, the most pleasant smell in the world.
According to Current Biology, experts consider the smell of vanilla the most pleasant smell in the world, followed in second place by the smell of ethyl butyrate (a chemical compound) that resembles the smell of peach. And that the smell of azovaleric acid, which is found in some foods such as cheese, soy milk, apple juice, and in the sweat of the feet, is the bad smell.
According to the magazine, experts reached these results from a study of 235 people representing different ethnic groups.
It became clear to the scientists also that the cultural level has no influence in the choice of scents. Because this issue is related to the structure of molecules and personal preference, which may be related to genetics and level of education.
According to the researchers, one possible reason that Homo sapiens considers some smells more pleasant than others may be that it increases the chances of survival during evolution.
