1, steamed rice with raw water causes cancer?
It is said that cooking with raw water will cause cancer because it contains chlorine. Is it true?/You don't say. /You don't say.
Raw water actually refers to unsterilized water and cold water. For people living in towns, raw water often refers to tap water that has not been boiled.
The tap water that has not been boiled does contain residual chlorine. This is because the tap water we are drinking now needs chlorine disinfection.
Natural water naturally contains all kinds of bacteria. Because it has not been disinfected, there may be dangerous molecules such as pathogenic bacteria and parasites in raw water, which may produce various toxins. If you drink it, you may get infected, which may easily lead to acute gastroenteritis, viral hepatitis, typhoid fever, dysentery and parasitic infection.
Chlorine treatment is a common method. Chlorine will form hypochlorous acid and hypochlorous acid radical when added to water, which has super oxidation ability and can kill many kinds of bacteria.
So, is chlorine in tap water really carcinogenic? Can you cook or not?
The World Health Organization (WHO) stipulates that the residual chlorine in tap water should not exceed 5 mg/L, and the minimum chlorine content in drinking water should not be lower than 0.05mg/L and the maximum limit is 4 mg/L. In fact, the residual chlorine content in tap water should be controlled below 1mg/L or even lower.
In addition, IARC, the International Center for Research on Cancer, classifies chlorine into the third category of "carcinogen classification", that is, "there is not enough information to determine whether the substance is a human carcinogen".
And even if there is a small amount of residual chlorine, it will evaporate when cooking and heating, and it is almost gone. Therefore, we don't really have to worry too much about residual chlorine.
Some people worry, what if there is too much chlorine in the water plant during disinfection?
In fact, it is easy to distinguish, because chlorine itself has a pungent smell. If you smell this, it means there is something wrong with the water quality. If you are really worried, you may not need this kind of water at all.
Cold water is raw water. Have diarrhea after drinking?
Many people think that cold water is raw water, and drinking it will cause diarrhea.
In fact, raw water refers to water that has not been sterilized. It mainly means that there is no sterilization treatment, which has nothing to do with its temperature.
Because there may be dangerous molecules such as pathogenic bacteria and parasites, drinking directly is really easy to cause disease, and diarrhea is a trivial matter. You know, in human history, many infectious diseases and plagues were spread through water sources, causing countless deaths. Therefore, generally speaking, we all advise people not to drink raw water.
But whether drinking raw water will cause diarrhea depends on the specific situation. If it is raw water in the sewer, you must not drink it. But if it is a relatively clean place, it is not necessarily harmful. For example, in many places in China, we are still drinking raw water from well water directly.
As for the tap water we use now, it is all sterilized, and even if we drink it directly, it will not cause diarrhea.
However, raw water often has great risk uncertainty. After all, none of us can see whether there are harmful microorganisms in the water. The best way is not to drink any raw water.
Boiled raw water, the shelf life is only 16 hours?
If the leaves of cold rice are left for a long time, there will be bacteria. However, it is completely deceptive to say that it only has a shelf life of 16 hours.
First of all, it is totally unreliable to evaluate the safety of boiled water by shelf life.
The shelf life is a promise made by the producer to the consumer, not a period of complete non-deterioration. Moreover, boiled water does not distinguish between producers and consumers, and there is no shelf life at all.
Secondly, whether leaving water for too long will cause harm to human body mainly depends on whether there are pathogenic bacteria.
You know, there are 1-2 kilograms of bacteria living in human intestines all the year round, and the number is as high as 100 trillion. These bacteria are everywhere in life, in the mouth, face, hands and air. Not all bacteria are harmful, and the bacteria that cause human diseases are mainly "troublemakers"-pathogenic bacteria. Common are Salmonella, Staphylococcus aureus, Escherichia coli and so on. As long as there are no troublemakers, it will not affect human health.
Unless someone puts the kettle in the public toilet with the cup uncovered, they can drink it for a day or two.
2. How to make a delicious rice cooker?
1. peanut oil
When cooking canned rice, add a spoonful of salt and a few drops of peanut oil to water and mix well, then pour it into indica rice. The taste of rice is hard to compare with that of japonica rice.

3. vinegar
Add a few drops of vinegar when steaming rice, and the cooked rice will be more fragrant and have no vinegar taste at all. It is best to prevent rancidity.
4. Salt+lard
Modern people like to keep in good health and seldom store lard at home. As everyone knows, when cooking, add a little salt and lard, and the cooked rice is full of fragrance.
5. beer
I don't know what to do with the old rice that has been left for a long time. When cooking, she adds some beer in the normal proportion. Unexpectedly, the cooked rice is as refreshing as fragrant rice.
6. Rice wine, white wine or yellow wine
When frying rice, drop a few drops of wine into the rice. The fried rice is fragrant and loose, and it is absolutely delicious to eat in your mouth. If you encounter raw rice, you can shovel the rice, add 2 spoonfuls of rice wine, white wine or yellow wine, and cook for a while with slow fire.
7. Onions
What should I do if the rice is burnt? You can put an onion in the rice and cover it for a while.
8. tea
Pour the brewed tea into the rice and cook it in the normal way. The brown rice cooked in this way is rich in nutrition, bright in color, fragrant and delicious.
9.olive oil
When cooking, adding some olive oil to the rice can delay the rising speed of sugar in the rice without causing harm to the stomach.
In fact, it is not true that cooking with raw water will cause cancer, unless there is chlorine in raw water, but chlorine is a very pungent smell, which can generally be smelled. Usually, everyone should try to drink boiled water, that is, boiled water should be warmed before drinking, and it should not be left for too long. It is best to drink it within 16 hours.
