Tableware material classification:

1. Ceramic tableware

In the past, ceramics were recognized as non-toxic tableware, and there were reports of poisoning caused by the use of porcelain tableware. It turns out that the beautiful coat (glaze) of some porcelain tableware contains lead. If the temperature is not enough when firing porcelain or the glaze ingredients are not up to standard, it may make the tableware contain more lead. When food comes into contact with tableware, lead may overflow the surface of glaze and mix into food.

2, glass tableware

clean and sanitary, generally does not contain toxic substances. But glass tableware is fragile and sometimes "moldy". This is because the glass will be eroded by water for a long time, which will produce substances harmful to human health and should be washed away with alkaline detergent frequently.

3, enamel tableware

Enamel products have good mechanical strength, strong, not easy to break, and have good heat resistance, which can withstand a wide range of temperature changes. Smooth texture, compact and not easy to be contaminated with dust, clean and durable. The disadvantage of enamel products is that they are often cracked and broken after being hit by external forces.

4. Wooden tableware

The biggest advantage of bamboo and wood tableware is that it is convenient to obtain materials and has no toxic effect of chemicals. But their weakness is that they are more prone to pollution and mildew than other tableware. If you don't pay attention to disinfection, it is easy to cause intestinal infectious diseases.

5, copper tableware

Many people use copper tableware, copper pots, copper spoons, copper hot pots and so on. On the surface of copper tableware, you can often see some blue-green powder, which is called copper rust. It is an oxide of copper, which is non-toxic. But for the sake of cleaning, it is best to polish the surface of copper tableware with sandpaper before loading food.

6. Iron tableware

Generally speaking, iron tableware is non-toxic. But iron is easy to rust, and rust can cause nausea, vomiting, diarrhea, upset, poor appetite and other diseases. In addition, it is not advisable to use iron containers to hold cooking oil, because oils are easy to oxidize and deteriorate when stored in iron for too long. At the same time, it is best not to cook foods and drinks rich in tannins in iron containers, such as juice, brown sugar products, tea and coffee.

7, aluminum tableware

non-toxic, light and durable, good quality and low price, but aluminum accumulates too much in the human body, which can accelerate aging and have a certain adverse effect on people's memory. Aluminum tableware is not suitable for cooking acidic and alkaline foods, and it is not suitable for long-term storage of meals and long-term storage of salty foods.

8. Plastic tableware

Commonly used plastic tableware is basically made of polyethylene and polypropylene. This is a non-toxic plastic recognized by most countries' health departments. Sugar boxes, tea trays, rice bowls, cold water bottles and baby bottles on the market are all of this kind of plastic. However, polyvinyl chloride (PVC) with similar molecular structure to polyethylene is a dangerous molecule. A rare hepatic hemangioma has been found, which is almost related to people who often contact PVC.
