What's the garbage of chopsticks?

What kind of chopsticks are made of?

1. Bamboo chopsticks
There are two kinds of chopsticks: non-carbonized bamboo and carbonized bamboo
Non carbonized bamboo is bamboo without any treatment.

Carbonized bamboo is a kind of bamboo processed by special technology
The difference between the two is that the color of non-carbonized bamboo is lighter and that of carbonized bamboo is darker.

Advantages: bamboo chopsticks are environmentally safe, natural and non-toxic, and are the first choice for many families, especially carbonized bamboo chopsticks, which have the characteristics of high stability, are not prone to mildew and deterioration, and can be used for a long time.

Disadvantages: due to the large difference between the bamboo's material skin and interior, once the bamboo chopsticks are put into the disinfecting cupboard, they will be bent and deformed.

2. Wooden chopsticks
Advantages: chopsticks are pure natural materials, without the toxic effect of chemicals, so they are safe to use.

Disadvantages: wooden chopsticks are more likely to be polluted and moldy than other chopsticks

If you do not pay attention to cleaning and disinfection, it is easy to cause intestinal infectious diseases.

3. Metal chopsticks
Metal chopsticks are usually made of stainless steel

Advantages: stainless steel chopsticks are beautiful, easy to use, corrosion-resistant and rustless

shortcoming
1. Poor thermal conductivity
Easy to burn

2. Stainless steel is made of iron-chromium alloy mixed with nickel, molybdenum and other metals. Some of these metals are harmful to the human body. Therefore, it should be noted that salt, soy sauce, vinegar, etc. should not be placed for a long time when using, because the electrolyte in these foods will react with stainless steel in long-term contact so that harmful substances will be dissolved.

4. Melamine chopsticks
Melamine chopsticks are formed by heating and pressing melamine resin powder
Advantages: melamine chopsticks are safe and sanitary, non-toxic and tasteless, not easy to break, acid and alkali resistant, superior resistance to oil, acid, alkali and all kinds of solvents, good temperature resistance, low thermal conductivity, and easy to hold even when containing hot goods

shortcoming
1. Due to the particularity of the molecular structure of melamine plastics, cracking will occur under high-temperature baking.

2. Due to the high price of melamine powder, some illegal businesses directly use urea-formaldehyde molding powder as raw materials for production in order to pursue profits, while tableware made of urea-formaldehyde is harmful to human body.

Matters needing attention
1. Check whether there is obvious deformation, color difference, smooth surface, uneven bottom, clear Decal pattern, wrinkle and bubble, and whether there is discoloration when wiping the colored tableware back and forth with a white napkin.

2. Melamine tableware can't be washed with steel wire ball, which will wash off the glossiness of the tableware surface and leave many scratches, so it's not recommended to wash with steel wire ball. If the dirt is very difficult to wash, it's recommended to soak it in detergent water, and then wash it with a dishcloth.

V. silver chopsticks
Advantages: silver chopsticks are harmless to the human body. Silver can play a bactericidal role. Silver can form positively charged silver ions in water. These silver ions can adsorb bacteria on them, making the enzymes that bacteria rely on to breathe lose their function, and making bacteria unable to survive.

Silver is a heavy metal, which is harmful to people, but it is very stable, and the silver ion dissolved in water is extremely small, so you don't need to worry about the harm to the human body, you can use it safely!
