If the refrigerator is not cleaned for a long time, it will produce many pungent smells, making people feel sick. So what is the source of these odors? Let's have a look with Xiao Bian.

Some people may think that the low-temperature environment in the refrigerator can inhibit the survival and reproduction of bacteria. How can there be a strange smell?

In fact, although the low-temperature environment in the refrigerator can inhibit the survival and reproduction of bacteria, it cannot completely kill them. When our food is stored for a long time, bacteria will decompose the food, and then hydrogen sulfide, mercaptan and other products will be produced, leading to the so-called odor in the refrigerator.

At this time, we can place some refrigerator deodorant, which can be used to absorb and remove the odor.

Type of refrigerator deodorant

Masking deodorant

The main component of this refrigerator deodorant is aromatic agent. During the use, the aromatic agent will slowly volatilize, which can cover up the odor of the refrigerator. However, this simple method of using flavor to suppress flavor is gradually eliminated, because the consumption of aromatics is very fast. When it is almost used up, there is no way to cover up the strange smell of the refrigerator. The effective time is relatively short, and it needs to be replaced constantly, which is very inconvenient.

Chemical deodorant

The odorous substances are converted into odorless substances through chemical reaction, which is usually composed of carrier and deodorizing chemical active substances, and can not be regenerated after reaction.

Physical deodorant

The refrigerator deodorant that uses physical action to eliminate odor mainly uses the principle of gas diffusion and adsorption.

Porous deodorants mainly include Activated carbon As a material, activated carbon is a very good adsorbent with a high specific surface area (the surface area of a unit mass of material) and a strong "physical adsorption" effect. Some organic compounds can be adsorbed to achieve the purpose of deodorization.
