The smell of earth+the smell of blood. ...
How did the earthy smell of the soil come from?
The natural smell in the air after rain is due to a trace of ozone.
There are also sayings that actinomycetes and volatile oils from flowers and trees (only heard of air fresheners).
Post specific materials:
Most people have noticed that there is a special smell in the air after rain. This often reminds people of spring, just as the smell of just mowing grass reminds people of summer. You will find that many poems and enlightenment works talk about it. How did this smell come from?
This smell is usually associated with storms, but it may actually be caused by many things. One of the more pleasant smells we often smell in the Woods after rain is actually produced by bacteria! Actinomycetes is a typical filamentous bacteria, which grows in warm and humid soil. When soil is dry, actinomycetes produce spores. The impact of rain and moisture lifted these tiny spores into the air and attached them to the gas solvent (like fresh air spray) formed by moisture in the air after rain. Humid air can easily carry these spores and be inhaled by us. These spores have a special earthy smell, which often reminds us of rainfall. Actinomyces are very common. They exist in every corner of the world, which is why this pleasant smell is so common after rain. This kind of bacteria grows easily in wet soil and produces spores in dry soil, so the smell is strongest after the first rain at the end of the dry season. Of course, after most storms, you will smell rain to some extent.
The acidity of rain produces another smell. Due to the chemical substances in the atmosphere (especially in urban environment), rainwater often shows certain acidity. When such rain comes into contact with organic debris or chemicals on the ground, some chemical reactions that can produce odor will occur. Acid rain will wash away the soil, release minerals embedded in it, and react with chemicals (such as gasoline) to make their smell stronger. The smell produced by these reactions is usually a little worse than that of spores, which is why the smell after rain is not always pleasant. Like the odor produced by bacterial spores, the odor produced by chemical reactions is strongest after the first rain after the dry season. This is because after a heavy rain, the chemicals on the ground will be diluted, so they will no longer react with the rain.
Another smell after rain comes from the volatile oil released by flowers and trees. Then the oil collects on the surface of rocks and other objects. Rain reacts with oil on rocks, bringing oil into the air in gaseous form. Similar to the smell produced by bacterial spores, most people find this smell fresh and pleasant. Because of its fragrance, it is even sold in bottles!
These are just a few common smells after rain, and there will be other smells after rain. The impact of rain and moisture will emit a lot of aromatic substances, especially the humid air after downpour is very beneficial to the diffusion of these particles in the air. Therefore, when you talk about the smell after rain with your friends, you may not be talking about the same smell. However, both of you will feel that the air will be much fresher after a good rain.
What are the spices to remove the earthy smell?
Among spices, shellac, cinnamon, star anise and cumin can remove fishy smell. The deodorizing components are as follows:
1, lemon
When steaming fish or making shrimp, you can learn from western food and squeeze some lemon juice to neutralize the smell of seafood.
Step 2 cook wine
Alcohol has unique solubility and volatility to fishy substances, so cooking wine is an excellent seasoning to remove fishy smell and relieve boredom, which can be used in various ingredients, such as eggs and fish. When cooking, you can marinate the meat with cooking wine first, which can not only remove the fishy smell, but also make the meat fresh and delicious.
3. vinegar
The fishy smell produced in meat is an alkaline compound, which can be neutralized by adding proper amount of vinegar when cooking. However, because the taste of acetic acid is * * *, it is necessary to control the amount when adding it, so as not to affect the taste of the dish. Black vinegar should not be cooked for a long time, just add it before cooking, so as not to lose fragrance. Slightly boiled white vinegar can dilute the sour taste.
4. energy
Ginger is a hot food, which can not only neutralize the coldness of ingredients, but also deodorize. Ginger is simply a sharp weapon to remove flavor. Ginger is the best choice whether it is fragrant or fish deodorizing.
5. Dry flour
Using dry flour to remove fishy smell may not be tried by many mothers. Dry flour can remove the fishy smell. After descaling, it is a good method to rub the fish with dry flour for a while and then rinse it for a while. The fishy smell will be greatly reduced, and flour will not bring other flavors to the fish.
6, spices
Spices are essential condiments when cooking pot-stewed vegetables. Gum, cinnamon, star anise, cumin and other spices are not only unique in flavor, but also natural experts in deodorization. However, it is not recommended to put too much, so as not to mask the taste of the meat itself. This spice is generally used to deodorize pork, mutton and other meats.
What should I do if the house smells earthy?
1. Fill the container with cold water, then put some vinegar in a ventilated room and open the furniture door. This can not only protect the coating surface on the top of the wall by properly evaporating water, but also absorb and eliminate the fishy smell of the soil;
2. Buy some pineapples, put a few in each room and more in the big room. Because pineapple is a kind of crude fiber fruit, it can not only absorb the smell of paint, but also give off the fragrance of pineapple, and also accelerate the removal of soil odor, so as to achieve the best of both worlds.
3. To quickly remove the earthy smell, you can soak cotton balls with citric acid and hang them indoors and in wooden furniture;
4. Newly renovated houses often have the pungent smell of various chemical raw materials such as Tianna water. Put a broken jackfruit (a tropical fruit that looks like durian, but it is by no means durian! ! It is not good to put durian! ) indoors, because jackfruit is big (generally as big as watermelon) and has a particularly strong fragrance, it can absorb the odor in a few days;
You can go to the market and choose some high-tech deodorant cleaners, which can remove the harmful gases emitted by newly renovated houses and new furniture. According to relevant sources, these deodorizing cleaners are generally imported products, which use ammonia compounds to react with harmful substances to deodorize and clean. In the newly renovated room, you can pour this deodorizing cleaner into a plate, put the plate in each room separately, and combine with the method of scrubbing and deodorizing to effectively remove the unpleasant smell in a few days;
6. It is also very effective to put items such as orange peel and lemon peel in the room, but their effect will not be quick.

You've cooked it, how can you get rid of the fishy smell? The fishy smell has already entered the fish. Generally, you can't stew fish with seasoning.
How can you remove the earthy smell in water?
Water containing minerals such as calcium and magnesium salts is called "hard water". Rivers, lakes, wells and springs are all hard water. Tap water is obtained from rivers, lakes or well water after precipitation, sediment removal and disinfection. Hard water, too. Fresh rain and snow, the water does not contain minerals, is "soft water." After the water is boiled, some of it evaporates and precipitates insoluble calcium sulfate (gypsum is calcium sulfate containing crystal water). The original dissolved calcium bicarbonate and magnesium bicarbonate decompose in boiling water, releasing carbon dioxide into insoluble calcium carbonate and magnesium carbonate (the main components of limestone and dolomite). This is the origin of scale. When washing clothes with hard water, calcium and magnesium ions in the water combine with soap to form flocculent precipitation of calcium fatty acid and magnesium fatty acid, which is the origin of "bean curd residue". Washing clothes in hard water wastes soap. Scale grows in the kettle, which is not easy to transfer heat and wastes fuel. For a family, these wastes are not serious. For the factory, the problem is big. Some large boilers used for heating and steam supply in factories emit several tons of steam per hour, which is equivalent to burning several tons of water. According to the test, one ton of river water contains about 1.6 kg of minerals; The minerals in a ton of well water are as high as 30 kilograms. How amazing the amount of scale deposited on the inner wall of boiler by hard water when transporting dozens of tons of steam a day! Scale has been formed in large boilers, which is like building a thermal insulation stone wall between the steel plate and water on the boiler wall. The steel plate of the boiler can't touch the water, and the fire in the furnace keeps burning the steel plate red. At this time, if the scale cracks, water will immediately leak to the high-temperature steel plate and evaporate quickly, resulting in the pressure in the boiler soaring and explosion. The power of boiler explosion is no less than a blockbuster! It can be seen that the harm of scale must not be taken lightly! Therefore, in factories, proper amount of sodium carbonate is often added to water, so that calcium and magnesium salts in water are precipitated and removed, and water becomes soft water. Passing hard water through ion exchange resin can also remove minerals and get soft water. The kettle and thermos bottle at home have grown scales. How to remove it? Carefully boil the kettle until it is just dry, and then soak it in cold water immediately. When it is hot, it is hot, and when it is dirty, it is cold. Because of the different degrees of expansion and contraction of aluminum and scale, the scale will break off from the boiler wall. The main components of scale are calcium carbonate and magnesium carbonate, which can change chemically with acid. According to this principle, pour some vinegar into the kettle and heat it on the fire, only to see the small bubbles released from the weighing pan, and the weighing pan was shattered. Dilute hydrochloric acid can also remove scale. Dilute hydrochloric acid is easier to digest calcium carbonate than vinegar. But when operating, be very careful not to let the hydrochloric acid handle corrode. You know, hydrochloric acid and aluminum react easily. If it's an enamel kettle, the enamel hasn't fallen off yet, so it's good to use dilute hydrochloric acid to remove the scale. It is no problem to remove the scale from the thermos bottle like this.
