Why are bamboo chopsticks deformed after being sterilized at high temperatures?

And there is also the reason that the bamboo products due to the density of the reason, put into the sterilizer high temperature disinfection, very easy to deformation, deformation of the chopsticks is basically "waste" chopsticks. Before dining should be carefully observed if the chopsticks surface spots, most likely breeding "aflatoxin" carcinogens, it is best to hurry to replace. The chopsticks smelled sour, under the rinse, rubbed loudly, and then inserted into the chopsticks tube even if it is washed. Experts pointed out that this method of washing, chopsticks may not be thoroughly washed, bacteria will soon grow. I have done an experiment, in order to be safe, I bought bamboo chopsticks and bamboo toothpicks back in the use of bamboo chopsticks before the bamboo chopsticks (because the bamboo chopsticks to often change, so buy more) and bamboo toothpicks, put into a pot of water boiled all over the traditional use of thousands of years of our ancestors, compared to the more economic, affordable, safe; and stainless steel chopsticks, although said to be durable, but the cost is too expensive, a pair of stainless steel chopsticks can cost as much as the cost of a pair of bamboo chopsticks, the cost of a pair of stainless steel chopsticks is more than the price of a pair of chopsticks, the cost of a pair of chopsticks can be more than the cost of a pair of stainless steel chopsticks. The cost of chopsticks can be worth the cost of bamboo chopsticks plastic chopsticks plastic chopsticks lightweight, smooth, good cleanup, but plastic chopsticks brittle texture, easy to deform when heated, resulting in substances harmful to the body.

Eating food also requires chopsticks; as something so close to everyone's life, its safety is more worthy of everyone's "attention". Chopsticks on the market are made of a variety of materials, which are more reliable and safer to use? Chopsticks with moldy spots are also a place for aflatoxins. Bamboo and wood chopsticks are cheap, but they need to be replaced on a regular basis.

Bamboo grows into a wide range of applications, bamboo chairs, bamboo benches, bamboo curtains, bamboo baskets, bamboo baskets, bamboo bowls, bamboo chopsticks, bamboo flooring, and so on, indicating that it is green, safe and reliable. So using bamboo chopsticks is quite common. There is no need to mention other material chopsticks. There are a few pairs of old bamboo chopsticks at home that have been made for more than ten years and are not moldy. Stainless steel chopsticks material do not know how, we have used the dowel imported very acid and alkali resistant, domestic dowel is not acid and alkali resistant, long will have deformation of the situation. In addition, these two materials should be carefully cleaned and sterilized after the purchase of the product, because now the product is a mass production, raw materials before in order to prevent moisture.
