Chopping board, also known as chopping board, is an essential item in the kitchen. It needs to be used every day to cut vegetables. If it is worn out, you have to buy a new one. The cutting boards sold in supermarkets are often processed in factories, and the boards may be contaminated with some harmful industrial substances. You need to clean a new one before you can use it. Now let's learn about the new chopping board cleaning and disinfection tips!
Cleaning method of new cutting board:
1. Wash the bamboo cutting board first after you buy it home. Use boiling water to clean it. Because the surface of the cutting board is covered with wax when leaving the factory, the wax on both sides should be washed off. After washing, soak in concentrated salt water for 1 hour. The salt is hygroscopic, which can prevent the cutting board from drying and cracking.
2. After the washed bamboo cutting board is dried, the problem of heat expansion and cold contraction is dealt with. The method is to drill a hole in the middle of the cutting board, about 5 mm to 10 mm in diameter. Plug the hole with a small wooden bar (you don't need to do it if you don't have drilling conditions at home).
3. The bamboo cutting board should be coated with a layer of protective layer after moisture-proof and heat expansion and cold shrinkage treatment are completed. Bring the cooking oil to a boil and sprinkle it evenly with hot oil, so that the cutting board is in full contact with the oil. Then cool dry, let the oil be absorbed by the chopping board, and finally wash with water.
The disinfection method of the new cutting board was as follows
1. Washing, scalding and disinfection
First, clean the surface and gap of the board with a hard brush and clean water, and then rinse it again with 100 ℃ boiling water.
2. Sun disinfection
Ultraviolet rays in the sun can kill bacteria. When the board is not in use, it should be exposed to the sun. In this way, it can not only kill bacteria, but also dry the board and reduce the reproduction of bacteria.
3. Vinegar disinfection
Cut the fish plate, as long as sprinkle some vinegar, dry in the sun, and then wash with water, there will be no fishy smell.
4. Disinfection with salt
Every time you use the chopper, scrape the residue on the board with a knife, and sprinkle a layer of salt on the board every 6-7 days, which can not only kill bacteria, but also prevent the board from drying and cracking.
5. Sterilization with scallion and ginger
A long time's use of the cutting board will produce a strange smell. Use green onion or ginger to wipe the chopping board all over, and then wash it with hot water and brush at the same time. The strange smell will disappear.
6. Ultraviolet disinfection
Put the board in the sun for more than 30 minutes, which can not only kill bacteria, but also dry the board and reduce the reproduction of bacteria.
The newly bought cutting board should be handled with care
First, wash the surface wax with boiling water; then soak it in concentrated brine for one day (boil water, add salt to heat, add no longer dissolve); remove foam, heat a can of oil and wait for cooling. When the temperature is about 70 ° C, coat the surface of the cutting board with hot oil, let it stand for a period of time, then apply and then apply. How many times? When the oil is almost absorbed, wipe the oil with paper and use a cutting board. In addition, if the cutting board is not used for a long time, it should be placed on the oil and stored.
How to prevent the new cutting board from cracking
1. First, wash the outer wax with hot water. After washing, be sure to soak in concentrated brine for a day. Concentrated brine is boiling water, heating salt, adding no longer dissolved. The purpose of soaking in salt water for a day is to make the wood surface salty. The salt is hygroscopic and can prevent wood from drying and cracking. After taking out the foam, heat a pan of oil and wait until it is cooled to about 70 degrees. Smear it on the surface of the chopping block and let it stand for a period of time. Then apply it and apply it several times. When the oil is almost absorbed, dry the oil with paper and use a cutting board. In addition, if the cutting board is not used for a long time, it should be painted and stored in a safe place.
2. After purchasing the new cutting board, put the cutting board on the bracket. Apply vegetable oil on both sides, dry and repeat until the vegetable oil is saturated in the wood for three minutes. In a few days, fuel consumption depends on the size of the cutting board, and usually only costs more than 250 grams. After vegetable oil treatment, no matter how long, the cutting board will not break.
