Eating is a great enjoyment in life. Most people in modern times think about what they want to eat every day, and what to eat can be healthy and more nutritious. However, they ignore the importance of cutlery. Today, the editor will tell you that tableware also has a lifespan, and different materials have different usage times.
1. Wooden tableware Most of the tableware made of wood are chopsticks and bowls, which are more common in the market mahogany and holly. Good wood needs to choose wood with a higher density, so it will feel heavy when you put it in your hand, and bacteria are not easy to breed. Longevity: Dense wood will last longer relative to the actual type of wood.
2. Bamboo tableware Bamboo tableware is also very common, but due to the bamboo material itself, the gap between the tiny fibers is not very dense, so it is easy to store oil and bacteria. Therefore, you need to be careful when cleaning, and dry it quickly after washing, otherwise it is easy to mold and produce bacteria. Lifespan: 3-6 months. If cracking or mildew appears prematurely, it should be replaced immediately.
3. Plastic tableware
The appearance of plastic is more beautiful, and it also avoids the disadvantage that bamboo and wood materials are easy to mold. But plastic also has some potential problems, such as easy aging. The plastic that is more commonly used in tableware is polystyrene, although polystyrene does not release toxic substances, but if used for a long time, coupled with the action of light, or degrades, it slowly softens.
Longevity: When plastic cracks, it’s time to replace it.
4. Stainless Steel Cutlery
There is a protective film on the stainless steel surface, which can effectively prevent oil and bacteria from remaining. However, with the increase of use time, the surface of stainless steel chopsticks will be damaged by the acid, alkali and salt in the food.
Longevity: If there are obvious scratches on the stainless steel surface, you can buy new cutlery.
5. Ceramics and Glass
Porcelain and glass are mostly silicates and can be used as long as they don’t break into pieces. It should be noted that due to glazing, the surface of porcelain often contains some heavy metals, while glass will add some metal minerals to increase the refractive index
(such as adding lead to crystal glass), so be sure to choose products with guaranteed quality when purchasing.
6. Imitation porcelain tableware
Some imitation porcelain tableware (ceramic tableware at first glance, but can be judged to be plastic from details such as hand feel and weight) will decompose into melamine and formaldehyde under the action of acid (vinegar). If you are often jealous, do not Suitable for this type of cutlery.
Lifespan: Generally 2-3 years, depending on how it is used, and imitation porcelain tableware is not resistant to high temperature.
In addition to the above, there will be some chopsticks, spoons or other knives used for frying in life that will have a shorter service life and should be replaced more timely.
