1. Ceramic tableware
This is the choice of most families, this kind of ceramic bowl is beautiful on the outside and easy to clean, so it becomes the first choice. But ceramic tableware is best to choose no pattern and smooth surface. In addition to the physical sense of the glaze color class of patterns or patterns are easy to be scraped off, but also because some of the coloring can be dissolved in water, easy to be accidentally eaten by the human body. Or in the purchase of ceramic tableware with patterns, choose "underglaze".
2. Enameled tableware
Enamel tableware can resist acid and alkali corrosion, chemical stability. But enamel tableware are made of iron products burned enamel, enamel contains lead silicate and other compounds harmful to the human body. In addition, enamel tableware service life is not long, easy to lose porcelain.
3. Plastic tableware
Mostly found in roadside stalls, micro source Jun asked colleagues, which no family use plastic tableware, this type of tableware not only can not withstand high temperatures, but also easy to precipitate toxic substances, and very difficult to clean. Check the literature and information WeiYuanJun also found that this type of tableware in the process will also add some plasticizers and coloring agents. So this kind of tableware try not to use them to hold the high temperature food or direct heating.
4. Stainless steel tableware
Stainless steel tableware containing manganese, titanium, nickel and other trace elements, fast heat conduction is also environmentally friendly, and its ability to resist corrosion, so do not store soy sauce, vinegar, salt and so on for a long time, so that its stainless steel bowl with the occurrence of slow electrochemical reactions, resulting in the dissolution of hazardous substances out of the short-term storage of the impact will be negligible. Purchase time to recognize the regular manufacturers, recognize the bottom written 304 and 316 goods.
5. Aluminum tableware
Aluminum products are lightweight, durable and inexpensive. Although the relationship between aluminum tableware and human health has not been proved by a complete scientific research data, but most experts think that too much aluminum accumulation in the body will accelerate human aging. Therefore, in the use of aluminum tableware, do not shovel scraping, if scraping down the aluminum shavings best not to eat.
6. Titanium tableware
Titanium is a pure metal, made of tableware has the advantage of light quality. Because of the "pure" titanium metal, it will not react with some high-temperature strong acid and alkaline food. Therefore, titanium's corrosion resistance is very high, and it is both an ideal medical material and an ideal tableware material. However, there is a business publicity and the physical does not match the situation, the laboratory received a sample, is currently being tested, interested in micro-source jun can pay attention to.
7. Glass tableware
Glass tableware clean and hygienic, does not contain toxic substances, but the shortcomings are fragile, easy to cause cracking; and sometimes "moldy", if you see the surface generates white carbonate crystals, usually sodium silicate in the glass and carbon dioxide reaction in the air, it is detrimental to human health found that after the discovery of alkaline detergent can be used to remove.
8. Bamboo and wood tableware
Bamboo type of natural tableware itself does not contain toxicity, but when buying, pay attention to, some merchants in order to aesthetically pleasing will be brushed on the surface of a layer of lacquer, lacquer layer needs to be analyzed for composition. If you choose not to paint bamboo tableware, compared to plastic and metal chopsticks, the classification is more prone to microbial growth, mold and mildew, etc., if the surface grooves or cracks, it is also easy to hide dirt, so this type of tableware need to be replaced regularly and keep ventilated and dry.
9. Diamine tableware
Diamine tableware may be in the process, the use of antibacterial plastic part of the characteristics of its contact with microorganisms can be inhibited and killed, antibacterial plastic products of antibacterial properties are long-term retention of the characteristics. From the point of view of the development of antibacterial plastics at home and abroad in recent years, to polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC) and acrylonitrile-butadiene-propylene-ethylene copolymer (ABS) as the base of antibacterial functional plastics with the widest range of applications. The melamine-formaldehyde resin, which is the material of diamine tableware, can withstand temperatures from -30 to 120 ℃, and will decompose melamine and formaldehyde at high temperatures.
