1、The source of odor

(1) food spoilage is the main cause

Fruit: when apples are left to rot for too long, they give off a sour smell, which is like the sour smell of over-fermentation mixed with the smell of rotting flesh. When bananas are ripe, the skin turns black and the flesh softens and rots, there will be a pungent smell similar to alcohol fermentation, very unpleasant.

Vegetables: the leaves of green vegetables turn yellow and soft after being left for a long time, producing a putrid swampy smell, as if the rotten leaves had been soaked in water for a long time. When the white hairs appear on the surface of cucumbers and the insides become soft, will give off a pungent sour smell, nauseating.

Meat: improper preservation of fresh meat, a large number of bacteria will be decomposed into ammonia, hydrogen sulfide and other substances, producing a pungent ammonia smell, like the bad smell of toilets; seafood spoilage, fishy smell becomes very strong, also mingled with the stench of decay, as if in the seafood dump.

(2) risk of food residue

Sometimes, juices or debris from food will drip on refrigerator shelves, bottom drawers, etc. . These residues in the refrigerator's low-temperature humid environment, will gradually breed bacteria, produce odor. For example, if a box of fruit is not cleaned in time, the remaining juice can become a“Hotbed” of bacteria.

2、The spread of odor

The air in a refrigerator is not static, but constantly moving. When a certain part of the food released odor, with the help of air flow force, spread around in the refrigerator. Neither the top shelf nor the bottom drawer is immune to odors.

The vents quickly carry odors to every corner of the refrigerator; the fans force the air to distribute odorous molecules more evenly throughout the refrigerator, making the whole refrigerator full of bad odors.

3、The source of peculiar smell

(1) activity of cold-resistant bacteria

Many people think that the low temperature of the refrigerator will inhibit the growth of bacteria, but it is not the case. Bacteria such as Listeria monocytogene, Pseudomonas, etc. , feed on the nutrients in food and produce various metabolites in the process of food decomposition, many of which are the source of odors.

(2) hiding place of bacteria

These bacteria are also particularly cunning, preferring to hide in nooks and crannies, as well as hidden areas such as drains. The dirt and bacteria in the drains continue to multiply and release odors. What's more, these bacteria are so resilient that even after a regular cleaning, they can quickly re-emerge as a recurring odor problem.

Don't Cram too much: leave room in the refrigerator for air to circulate. If it's too full, the air won't circulate and odors can build up. Generally speaking, the filling capacity of the refrigerator should not exceed 80% of the volume.

(3) natural adsorption

Activated carbon package: activated carbon has a strong adsorption capacity, can effectively absorb refrigerator odor. You can put some activated carbon bags in every corner of the refrigerator and change them every 1-2 months.
