Can potassium permanganate be used for melon and fruit disinfection?

Potassium permanganate has a bactericidal effect, which uses its strong oxidation to kill bacteria, which can kill most of the intestinal bacteria. However, there is no need to use high concentrations, because potassium permanganate has strong oxidizing properties, which can cause the metal to be strongly oxidized and rust.

The method of disinfection of fish is as follows: 10 to 15 minutes of medicated baths, during which time to ensure that there is sufficient oxygen, preferably with an air pump; If the fish is found to have only adverse reactions during the medicated bath, the water should be changed immediately or moved to other containers, and oxygen should be fully supplied; For well water fish farmers, potassium permanganate should not be used to disinfect the fish.

Potassium permanganate is a strong oxidant, which can effectively kill bacterial propagules, fungi, bacterial spores and some viruses. Mainly used for ** mucosal disinfection, 100 200 mg liters; surface disinfection, 1000 2000 mg liters; Feed drinking water disinfection, 50 100 mg liters; Soaked eggs and disinfected at a concentration of 5000 mg.

Potassium permanganate, commonly known as gray manganese oxygen, has strong oxidizing properties and is a purple-black solid with crystalline luster. Potassium permanganate is easily soluble in water, and the solution is bright purplish-red. Potassium permanganate aqueous solution can destroy bacterial and microbial tissues due to oxidation, so it has a sterilization and disinfection effect.

Potassium permanganate solution can be used to wash wounds; It can also be used to disinfect tableware, tea utensils and fruits such as chopsticks and teacups. When using potassium permanganate to disinfect fruits, tableware and other items, first soak the items to be disinfected in potassium permanganate solution for a few minutes, and then rinse them with water. When using potassium permanganate solution for disinfection, pay attention to the solution to be used and prepared, placed for a long time, the disinfection effect will be reduced, and when the solution becomes brownish-yellow, it will be completely invalid.

It can oxidize and decompose the cell membrane of bacteria, so potassium permanganate can be disinfected.

Because of his strong oxidizing properties, the cell membrane of the bacteria is oxidized and decomposed, and the bacteria are finished.

Potassium permanganate oxidizes the active groups of the bacterium and presents a bactericidal effect.

Potassium permanganate can effectively kill various bacteria, fungi and tuberculosis bacteria. It also kills spores, but takes a long time to lift. Heating organics can accelerate oxidation reactions under acidic or alkaline conditions.

Under different pH conditions, the oxidation reaction is different. In an acidic solution, it is reduced to a colorless manganese compound. In a neutral or alkaline solution, it is reduced to a precipitate of brown manganese dioxide and protein complexes. Low concentrations of potassium permanganate have antibacterial, astringent, deodorizing and other effects.

Potassium permanganate can disinfect food, generally speaking, potassium permanganate solution with a concentration can be used to disinfect fruits, vegetables, tea sets and other items, and rinse with water after disinfection will not affect the human body. However, it should be noted that the use of potassium permanganate for disinfection should be prepared and used immediately, otherwise the solution will lose its disinfection effect if it is placed for too long.

Potassium permanganate can disinfect food, potassium permanganate liquid is called gray manganese oxygen, this substance has strong oxidation, it is a purple-black solid with crystalline luster. Generally speaking, potassium permanganate solution with a concentration can be used to disinfect fruits, vegetables, tea sets and other items, and rinse with water after disinfection will not affect the human body.

Potassium permanganate is easily soluble in water, its solution is bright purple red, and its disinfection and sterilization principle is to oxidize the bacterial microbial tissue, resulting in the destruction of the internal tissue of the rental letter burning bacteria, so as to achieve the effect of sterilization and disinfection. In addition to disinfecting vegetables, tea sets and other items, it can also be used to wash wounds and prevent wound infection.

It should be noted that when using potassium permanganate solution for disinfection, it should be prepared and used immediately, because if the prepared solution is placed for too long, its disinfection effect will be reduced. When the prepared potassium permanganate solution turns brownish-yellow, it also loses its sterilization and disinfection effect.

Potassium permanganate is a strong oxidizing agent, which is very oxidizing and is not suitable for washing fruits and vegetables.

Note: Potassium permanganate is black-purple, elongated prismatic crystals or granules with a blue metallic luster; Odorless; In contact with some organic matter or easily oxide, it is easy to cause light searching, soluble in water, lye, slightly soluble in methanol, acetone, and sulfuric acid, with a melting point of 240 degrees Celsius, stable, but contact with flammable materials may cause disasters. Substances to avoid include oak compound agents, strong acids, organic materials, flammable materials, peroxides, alcohols, and chemically active metals.
