Chinese people are used to using chopsticks for meals. Chopsticks are made of bamboo, wood, silver, and different chopsticks have different service life. How long can chopsticks be used? Will chopsticks cause cancer after long use? Let's introduce it together!
How often can chopsticks be replaced half a year!
Irregular replacement will lead to dirty chopsticks. To the naked eye, you may not see the difference between a pair of wooden chopsticks that have been used for half a year, one year and three years. But if you put them in a close-up lens of 500 times, you will see that the chopsticks that have been used for half a year have peeling off their skin, some places have been cracked, there are obvious small gaps, and there are yellow residues in the gaps. If you use chopsticks that have been used for one year, the wood surface has changed color and the grooves are vertical There are a lot of oil stains in the horizontal and concave parts. Chopsticks that have been used for 3 years are totally different. They can't be seen as wooden. The surface looks like a mushroom. The longer they are used, the higher the total number of colonies detected. Except for metal chopsticks, wooden and bamboo chopsticks will form small grooves on the surface, which are easy to retain bacteria and detergent, so it's recommended to change them once every six months

Because of the high frequency of use of household chopsticks, and long-term washing with water, it is easy to become a hotbed for bacterial growth, such as Staphylococcus aureus, Escherichia coli, etc. long term place chopsticks in the cabinet, may increase the probability of deterioration of chopsticks by more than five times

When using chopsticks, we should observe every day whether there are spots on the surface of chopsticks, especially mould spots. Bamboo products and wood products are the favorite living environment for mould spots, and as long as the environment is not dry and the humidity content of the substance itself reaches a certain level, it only takes one day to generate
The color of chopsticks needs to be changed immediately. It is found that when the chopsticks are used for 3-6 months, their color will become darker or lighter with time and frequency. The edible paint on the surface of chopsticks will be worn due to the frequency of use. As long as the chopsticks change compared with the time of purchase, especially the color, they need to be changed immediately
The color change of chopsticks indicates that the nature of the material itself must change. The factors that cause the color change are usually the adhesion of food, detergent, air and residues in the dining cabinet during use. The long-term accumulation of bacteria is also the main factor that causes the color change. If there are spots on chopsticks that are not bamboo or wood, it means that the chopsticks are likely to have mildew If the chopsticks are wet or bent or deformed, it means they have been damped or have been used for a long time, which is likely to have passed the shelf life; if there is obvious sour smell, they are all signs of pollution or expiration, so they can not be used again
Put the chopsticks in boiling water for half an hour every week, and then dry them in the air for reuse, which can achieve the effect of disinfection, and effectively and conveniently remove the mould in chopsticks
