To use the smell of books, you may have seen people around you who fainted, and even more so, you may be one of them. Just like the effect of diesel in some people, the smell of books often makes people smell it again and again. So what’s the reason for this? Let’s explain it simply from the window of science.
Even though it doesn’t come to our mind immediately when we think about it, at certain times we involuntarily we are looking for or what we inhale again and again when we find it scents has. As an example, we can think of the smell of soil that spreads after the rain. Or the smell of freshly mown grass can be given as an example. But undoubtedly the most common of these is the smell of diesel. There are countless scents like these around.
In this content, one of them is to the smells of books and why these odors cause some people very attractive We’ll tell you it’s coming. Although we will benefit from scientific explanations, this subject, which we avoid to explain in a technical way, is simpler than it is thought. Now, let’s take a look at why book fragrances are so popular.
The different chemicals in the content of the books are basically the cause of these odors. But there are certain differences between new and old book fragrances:
Let’s start with the new books first. There are 3 factors in total that we should keep in mind when evaluating the smell of these. Ink, paper and used for binding glue. When these three are blended together, we do not see the same chemical interaction every time. This is different books with different demands due to printing.
Due to this difference, the scents of new books also vary. In the beginning, these three materials that we have mentioned are actually a very prominent one. does not emit odor. But when they interact with each other VOC abbreviated as (Volatile Organic Compounds) volatile organic compounds they reveal. These also begin to emit a sweet odor over time.
New books also come with pleasant scents, but more intense scents are found in old books rather than them. What is the reason for this?
When you look at your old books, it is often due to the oxidation of both the pages. turn yellow as well as in the new books busier You see a scent emanating. This is due to the deterioration of cellulose and lignin in the structure of the paper in the intervening time.
As a result of this deterioration, many new organic compound emerges and over time; These compounds can be listed as benzaldehyde, vanillin, ethyl hexanol, toluene and ethyl benzene. a sweet scent emits.
So what do these scents look like?
Toluene and ethyl benzene a sweet scent benzaldehyde and furfural compounds when emitting almond It emits a reminiscent odor. If ethyl hexanol flower responsible for an odor reminiscent of its smell. When all of them come together over time, the scent we get from old books and which we describe as sweet emerges.
Here, the factor that determines the intensity of the smell is after the chemical mixture. age of the book we can say. Because old books are more lignin It contains the compound that gives the smell of vanillin.
Another issue is that the smell reminds a memory or a feeling:
with your ex you always listen stop listening to a song and leave after the years If you open it again, it is possible to go back to the old days and relive the feelings of that time. Sadness, regret, etc. What thoughts come next is up to you. a situation similar to this smell is also on the side.
When we smell a new scent, our olfactory system also works with memory. connected Because our brains can smell that smell with events, people or emotions at that time. reconciles. Just like our brain associates a song with a certain person in our ex-girlfriend example. The scent we smell is specially designed within the framework of our content. book scentIf we are in harmony with the feelings or events of that time, we can start to look for this smell to go back to those days.
In a 2017 study, a group of 79 people tried to guess what they didn’t know from their scent:
From books, especially old ones vanilla It is stated by most people that it has a reminiscent odor. In this study, the group trying to guess different objects from each other’s smell found the smell they got from the book the most. ‘to the chocolate’ likened it. The most received answer after chocolate is coffee it happened.
