As an important edible tableware, how to choose the bowl in a variety of material ?

1. Ceramic tableware

2. This is the first choice for most families, because of  this ceramic bowl outside beautiful and easy to clean. But the best choice of ceramic tableware is without patterns and smooth surface. In addition to the physical sense of the glaze type of pattern or pattern is easy to be scratched off, but also because some of the paint can be dissolved in water, easy to be accidentally eaten by the human body. Or choose "underglaze" when buying ceramic tableware with patterns.

2. Enamel tableware

Enamel tableware can resist acid and alkali corrosion, chemically stable. But enamel tableware are made of iron products fired on enamel, enamel contains compounds such as lead silicate harmful to humans. In addition, the service life of enamel tableware is not long, easy to drop porcelain.

3. Plastic tableware

Mostly seen in the roadside stalls, which not only can not withstand high temperatures, but also easy to precipitate toxic substances, and very difficult to clean. Some plasticizers and colorants will also be added during processing. So try not to use them to hold high temperature food or direct heating.

4. Stainless steel tableware

Stainless steel tableware contains manganese, titanium, nickel and other trace elements, thermal conductivity is fast and environmentally friendly, Its corrosion resistance is stronger, so do not store soy sauce, vinegar, salt for a long time, making its slow electrochemical reaction with the stainless steel bowl, causing harmful substances to be dissolved out, but the impact of a short period of storage is minimal. Recognize the regular manufacturers when buying,  the bottom of the goods 304 and 316.

5. Aluminum tableware

Aluminum products are lightweight, durable and inexpensive.Although there is no complete scientific research data to prove the relationship between aluminum tableware and human health, most experts believe that excessive accumulation of aluminum in the human body will accelerate human aging. Therefore,  do not shovel and scrape when using aluminum tableware， it is best not to eat if you scrape off aluminum shavings.

6. Titanium tableware

Titanium is a pure metal with the advantages of light quality. Because of "pure", it will not react with some high-temperature strong acid and alkali foods, So titanium corrosion resistance is very high, it is very ideal for both medical materials and tableware materials.

7. Glass tableware

Glass tableware is clean and does not contain toxic substances, but its disadvantage is that it is fragile and easy to burst; And sometimes it will be "moldy". If white carbonate crystals are seen on the surface, it is usually the reaction between sodium silicate in the glass and carbon dioxide in the air, which is harmful to human health. After discovery, it can be removed with alkaline detergent.

8. Bamboo and wood tableware

Bamboo all-natural tableware itself does not contain toxicity, but some businesses will brush a layer of paint on the surface for aesthetic reasons, the paint layer needs to be analyzed for composition. If without painting , it is more likely to breed microorganisms, easy to mold compared to plastic and metal chopsticks. If there are grooves or cracks on the surface, it is also easy to hide dirt, so this kind of tableware needs to be replaced regularly and kept ventilated and dry in time.
