What Should I Do If There Is A Strange Smell In The Refrigerator? Master These Methods To Keep Your Refrigerator Fresh And Odor-free

Where does the odor in the refrigerator come from?

Learn these 5 tricks and say goodbye to bad odors

I went to open the refrigerator door, and immediately there was a vague and strange smell that was difficult to express clearly in words, and it rushed towards me. It is estimated that many people have encountered this experience.

Obviously, the temperature of the refrigerator was set low enough, and the food was not obviously rotten, but the strange smell of various ingredients could not be dissipated.

Some people think it is caused by a malfunction of the refrigerator, and some people suspect it is caused by mixed food flavors. However, the actual cause may be more complicated than you think.

To solve the problem of refrigerator odor, you must first find out its source.

Many people mistakenly believe that the low temperature of the refrigerator can "kill" bacteria, but this is not the case.

Normally, the refrigeration temperature of the refrigerator is within the range of 0°C to 10°C. Such a temperature can only slow down the growth of bacteria, but there is no way to completely eliminate them.

Even if food has been stored in the refrigerator for an incalculable amount of time, it will still survive. Bacteria that are cold-tolerant, such as Listeria and Pseudomonas, will continue to reproduce and grow in an extremely slow but continuous manner. This reproduction and growth will cause food to spoil.

During the metabolic process of these bacteria, they will produce a variety of different gases with pungent odors, such as methylamine gas and hydrogen sulfide gas. When they are mixed together, they become the odor we smell in refrigerators.

In other words, it is not the odor "emanating" from the refrigerator, but the direct result of food deterioration and bacterial activity.

Store food in an airtight seal to prevent bacteria from getting in

The most critical step in preventing odor is to block the spread of bacteria between various different foods.

Many people are accustomed to stuffing leftover meals into the refrigerator with plates and bowls, or throwing purchased vegetables and fruits in with plastic bags indiscriminately. Doing so can easily lead to cross-contamination of bacteria on the food surface.

The correct way is to use crisper box or Fresh-keeping bag Seal food into portions.

The benefit of sealing is not only to prevent the exchange of flavors, but more importantly, to reduce the contact between food and air, thereby delaying the oxidation process and at the same time avoiding contamination caused by the interaction of juices between foods.

In particular, raw meat and seafood, which are easy to breed bacteria, must be sealed separately before being placed in the refrigerator.

Before putting fruits and vegetables in the refrigerator, clean them first

Many people buy vegetables from the wet market and put them directly in the refrigerator with soil, thinking that this can keep them fresh longer.

In fact, the soil attached to the surface of vegetables, rotten leaves, and even soft parts may become breeding grounds for bacteria.

For vegetables intended to be put in the refrigerator, first remove the old and bad leaves, rinse the soiled parts with clean water until they are clean, and then drain them slightly before placing them in a fresh-keeping bag or crisper.

There is a small detail here. Vegetables such as lettuce and spinach that are leafy vegetables are more likely to rot if they are placed in a wet state after cleaning. The most appropriate way is to use kitchen paper to slightly absorb the excess water.

The same is true for fruits. Fruits such as strawberries and blueberries, which are prone to mildew, should be washed before eating and kept in a dry state during storage. This can significantly reduce the chance of mold reproduction.

Blood stains on meat are a major culprit of odor

If there is always a fishy smell in the refrigerator at home, or an indescribable sour smell, then you might as well check the meat in the freezer or refrigerator.

There are blood stains remaining on the surface of the meat. The blood stains are rich in protein and iron. This blood stain is a "nutrient source" that bacteria particularly like.

Even if the temperature is very low, bacteria can still multiply slowly on blood stains and produce odor.

Therefore, whether it is pork, beef, or chicken, after buying it, it is best to rinse the blood stains on the surface with clean water, then use kitchen paper to absorb the water, then wrap it tightly with a plastic wrap or plastic wrap, and then refrigerate or freeze it.

If the meat is to be frozen, it is recommended that it be packaged based on the amount of food each time, and then frozen. This can avoid bacterial growth caused by repeated thawing on the one hand, and can also reduce the generation of odor on the other hand.

Zoning management, separation of raw and cooked food is the bottom line

There are actually "levels" of space in the refrigerator, and the temperatures in different areas are slightly different.

A simple and practical principle is: Cooked food on top, raw food on the bottom .

The temperature of the upper layer of the refrigerator is generally relatively stable, and is suitable for placing food such as leftovers, cooked food, yogurt, and cheese that can be directly eaten. The temperature of the lower layer is slightly lower, and is suitable for storing raw meat, raw fish, and seafood. The drawer layer has high humidity and is specially used for placing vegetables and fruits.

In the case of temperature fluctuations, the door rack is the largest. Items that are not very sensitive to temperature, such as eggs, drinks, and condiments, are more suitable to be placed on the door rack.

Separating raw and cooked food is effective in preventing cross-contamination of bacteria and allows the air inside the refrigerator to circulate more smoothly, thereby reducing the accumulation of odors.

Clean regularly and don’t wait until there’s a smell.

Many people remember to wipe the refrigerator after smelling a strange smell. In fact, the bacteria in the refrigerator have been multiplying for a while.

Cleaning your refrigerator regularly is the most effective way to prevent odors.

It is recommended to clean thoroughly once a month.

First, turn off the power of the refrigerator. When cleaning, take out all the food. Then use a warm soft towel dipped in special refrigerator cleaner or diluted white vinegar. Then carefully wipe every corner of the inner wall of the refrigerator, as well as every corner of the partitions and drawers.

The sealing strips should also be cleaned as this is the favorite place for mold to hide.

After wiping it clean, let the refrigerator dry naturally before turning it back on.

There is a not very complicated trick. After completing the cleaning operation, you can place a small box of baking soda in the refrigerator. Baking soda has the ability to adsorb odor molecules in the air, thereby keeping the air inside the refrigerator in a fresh state.

Baking soda usually only needs to be replaced once every two months. The cost is very low, but the effect is very real.

After all, the food placed in the refrigerator cannot "keep fresh forever." Even with the best sealing operation and partition management method, it cannot resist the continuous advancement of time.

Whether it is refrigerated or frozen food, remember to eat it as soon as possible.

Especially for food such as leftovers, it is best to eat them within two days. Meat and seafood should not be left in the freezer for more than three months!

Cultivate the habit of regularly cleaning the refrigerator, and check which items in the refrigerator have been left for a long time and need to be disposed of every time you buy groceries. This way, the odor will naturally have no place to hide.
