Nowadays, with the improvement of people's living standards, the quality of life is becoming more and more strict. For tableware materials, many of us are healthy, safe, beautiful and practical. We also need the service life of tableware. After all, different tableware have different service life and need to be replaced regularly after a period of time. So, how long does it take to change in the kitchen?
1. Ceramic tableware should be replaced immediately if there are cracks
The beautiful colored glaze on porcelain contains lead. When cracks appear, lead may overflow and mix into food. Therefore, ceramic tableware with cracks should not be reused. The service life and maintenance of tableware are inseparable. For ceramic, metal and other kitchenware, we can prolong their service life through careful maintenance. However, in case of cracks, deformation, porcelain removal and other phenomena, they should be replaced in time, and their health should not be affected for the sake of temporary "saving".
2. Bamboo and wood tableware needs to be changed once every six months
Their service life is generally six months to a year. Household chopsticks need to be disinfected once a week. Some chopsticks will carbonize and turn black when frying delicious food, which is easy to turn black and slag, hiding dirt and accepting dirt. Once the chopsticks are cracked, deformed and discolored, they will no longer be used.
3. If the coating of metal tableware is damaged, it shall be replaced
Many people think that metal tableware is safe and can be used for life, but it is not. Take the common iron pot as an example. Once the "edible oil layer" on the surface of the iron pot that protects it from rust falls off, the rust in the pot is easy to cause nausea, vomiting, diarrhea, loss of appetite and other symptoms. Enamel tableware is easy to crack, and substances such as aluminum silicate coated on the outside of enamel tableware will be accidentally transferred to food. Stainless steel is made of iron chromium alloy mixed with nickel, molybdenum and other metals, which also contains components harmful to human body. Therefore, when it is found that the tableware made of metal is scratched or the surface paint or coating falls off, it should be replaced in time.
