Can salt water be sterilized, can salt be disinfected

Salt water with high concentration can indeed kill bacteria but cannot kill viruses, and cannot replace disinfectant because it cannot kill viruses. Disinfectant refers to the preparation used to kill pathogenic microorganisms on the vector and make them harmless. Therefore, strictly speaking, salt water cannot play a role in disinfection.

Most organophosphorus insecticides can be quickly decomposed in an alkaline environment, therefore, if you are worried that the vegetable residue pesticide you buy back can not be cleaned, you can add 5 10 grams of edible alkali to 500 ml of water to prepare alkaline water, put the vegetables after preliminary rinsing into alkaline water, according to the amount of vegetables with enough alkaline water, soak for 5 15 minutes, and then rinse with water, and the effect of repeated washing 3 times is better. Some pesticides slowly decompose into harmless substances over time during storage. If conditions permit, it is better to store certain vegetables suitable for storage for a period of time (10-15 days) and wash them before eating, which can better remove pesticides.

Celery, cabbage, green peppers, beans, etc. generally use carbamate insecticides, these pesticides will speed up the decomposition rate with the increase in temperature, therefore, you can blanch the cleaned vegetables in boiling water for 2 5 minutes and then take them out immediately, and then wash them with water 1 or 2 times, and then put them in a pot to cook into dishes. For green leafy vegetables, such as spinach, lettuce, bok choy, etc., first rinse off the dirt on the surface with water, and then use water to spread about 5 cm over the vegetable part, and soak it in running water for no less than 10 minutes, which can increase the dissolution of pesticides. Washing and soaking 2 or 3 times in this way can basically remove most of the residual pesticide components on vegetables.

It should be noted that when the holidays are approaching, some people often increase the spraying dose of pesticides in order to harvest vegetables, so do not buy in large quantities, you can buy vegetables that contain less pesticides or have strong resistance to pests and diseases, such as onions and garlic with special odors; When you find that there are drug spots on the surface of vegetables, or there is an abnormal pungent smell of chemicals, do not buy them; Crops that are continuously harvested (can be harvested for a long time and many times in a row), such as beans, peas, leek flowers, cucumbers, kale, etc., need to be sprayed with pesticides for a long time and continuously, and more attention should be paid to cleaning to reduce the amount of pesticide residues. Satisfied.

No, it can only play a role in rinsing dirt, not killing bacteria and microorganisms, and not playing a role in disinfection. Moreover, the irrigation can only be done with medical saline, otherwise the bacteria present in the water will be brought into the wound and cause infection.

Yes, it can be used as a substitute for alcohol!

1. The main chemical component of edible salt is sodium chloride, which can be disinfected. It is the most commonly used seasoning in cooking and one of the most important substances for human survival.

2. In addition to water, there are other minerals in the composition of animal cells, one of which is the main component is sodium ions, which cannot be generated by themselves and can only be ingested through daily food, and the body ingests sodium ions and replenishes them to various cell tissues.

3. However, this sodium ion can not be supplemented too much, that is, the concentration of sodium ions in the body cells can not be too high, can not exceed a certain concentration, if the excess exceeds this concentration, it will break the balance of the body's sodium ion concentration, then you must drink water to dilute it back to that concentration, which is why people can not eat salt and eat more salt to feel thirsty.
