What Should I Do If There Is A Strange Smell In The Refrigerator? Learn Why And How To Remove Odors With Baking Soda, Peels And More
When I opened the refrigerator door, there was an indescribable and indistinguishable smell rushing towards my face. I think many of my friends have had this annoying experience. They were obviously fresh ingredients that had just been bought. Within two days of being put in the refrigerator, the weird smell of leftovers, fruits and even raw meat began to "sneak around" everywhere. The reminder given by the Municipal Center for Disease Control and Prevention is very timely. The peculiar smell in the refrigerator not only ruins the mood, but may also indicate that bacteria are secretly growing. Many people think that the refrigerator is a "safety box" and that low temperatures will make everything go smoothly, but this is not the case. Today we will talk about the source of odor in the refrigerator, and there are several proven and effective ways to solve the problem, so that the refrigerator at home becomes fresh and comfortable again.
Source of odor: sealing and deterioration are the two main causes
If you want to completely get rid of the odor in your refrigerator, you must first figure out where it comes from. Information held by the Municipal Center for Disease Control and Prevention points to two main reasons. The first reason is that things with a strong smell are not stored properly. For example, if foods with strong odors such as leeks and durian are not stored in a sealed container, the odorous molecules they emit will wander around in the small closed space of the refrigerator and attach to other ingredients, forming a strange mixture of flavors. The second reason is more critical, that is, the food ingredients have become spoiled. The refrigerator compartment is generally kept at around 4°C. Yes, this is this temperature. It can indeed slow down the reproduction of bacteria, but it definitely does not stop it from multiplying. As long as time lasts a little longer, microorganisms such as bacteria and molds will still become active to decompose proteins and fats in food, thereby producing pungent smelly gases such as hydrogen sulfide and ammonia. Therefore, from the fundamental source, the odor is the result of the combination of storage habits and the freshness of the ingredients.
Baking Soda: The deodorizing master of chemical reactions
Among the many home deodorization methods, Xiao Su can be regarded as a "chemistry master". Its scientific name is sodium bicarbonate, which is quite active and can react with both acidic and alkaline substances. Many of the odor molecules in the refrigerator have acidic or alkaline groups. Baking soda can neutralize them and thus effectively remove odors. Easy to use: Take an appropriate amount of baking soda powder, place it in a wide-mouthed open container such as a small plate or glass, and put it directly into the refrigerator or freezer without a lid. Baking soda acts like a "smell sponge", slowly absorbing and reacting to surrounding odor molecules. I would like to remind everyone that baking soda itself is a food-grade material and is very safe. It needs to be replaced regularly, usually about once a month, otherwise it may become a source of pollution after the adsorption is saturated.
Peel and tea leaves: physical adsorption plus natural fragrance
If you don’t want to use chemicals, orange peels, grapefruit peels, or lemon peels that are readily available in your daily life are also very good choices. There is a rich pore structure on the surface of these peels, which itself has quite good physical adsorption capacity and can absorb odor molecules like activated carbon. What's even more lovable is that they have a fresh fruity aroma, which can add a natural fragrance to the refrigerator while absorbing odors. When operating, you only need to clean and dry the fresh peels and place them in the corner of the refrigerator. In addition, dry tea leaves have a very good adsorption effect and are especially suitable for absorbing odors in humid environments. However, it should be noted that if you plan to continue making tea, the tea must be properly packed in a sealed bag before putting it in the refrigerator. Otherwise, the tea will absorb all the flavors in the refrigerator and turn into "miscellaneous tea", which is not cost-effective. Regardless of whether it is peel or tea leaves, it is also recommended to replace it about once a week to maintain the effect.
Activated carbon and activated oxygen: deodorizing weapons upgraded with technology
If the first two are traditional household methods, then activated carbon and activated oxygen are "deodorizing weapons" powered by technology. Activated carbon is widely recognized as a high-quality adsorbent. It is made from charcoal, fruit shells and other materials that have been activated at high temperatures. Its interior is filled with tiny pores that cannot be seen by the naked eye, and its total surface area is amazingly huge. These pores are like countless small traps, which can firmly capture odor molecules and some bacteria in the air, achieving the dual effects of physical adsorption and chemical adsorption. Common activated carbon bags on the market can be opened directly and placed in the refrigerator, which is extremely convenient. The newer "weapon" is reactive oxygen. Its principle is more active. It uses its strong oxidizing properties to directly destroy the cell membranes of bacteria and mold, preventing the generation of odors from the source. Generally speaking, the higher the ambient humidity, the better the effect of active oxygen will be, especially suitable for humid environments such as refrigerators. No matter which one you choose, be sure to remember that they have a "shelf life". Activated carbon should usually be replaced after one or two months. Active oxygen generators also need to be maintained regularly according to the instructions given by the product, otherwise new problems may arise after failure.
Many methods for removing odor are described. In fact, the most basic solution is to pay more attention during daily use. First, buy according to your needs and try to buy as much as you can to reduce the time that ingredients remain in the refrigerator. Second, before food enters the refrigerator, store it in categories, separate raw and cooked food, and use crisper boxes or sealed bags to seal them. Especially foods that are prone to odor transfer, such as leeks and onions, must be sealed tightly. Third, to develop a good habit of regular cleaning, it is recommended to empty the refrigerator every other month or quarter, use a mild detergent to scrub the inside, and at the same time, check and discard expired or spoiled food. Only by controlling from the source in this way can the refrigerator truly become a "freshness guard" for food instead of a "fermentation tank" for odors.
