Can eating self-heating hot pot lead to carbon monoxide poisoning? Is it safe to eat self-heating hot pot?

Self-heating hot pot is a popular way to eat now. Self-heating hot pot is more convenient to eat. Just boil it in water for about ten minutes, but the thing that cooks hot pot is lime. So is there any danger of poisoning by eating self-heating hot pot?

Can eating self-heating hot pot lead to carbon monoxide poisoning?

Self-heating hot pot has a special food heating bag, which is the key to hot pot heating. It's not high-tech products, it's quicklime! We all know that quicklime heats up when it meets water. When we put the ingredients with the bottom material into the upper layer, then heat the bag and put down that layer, add cold water, and after a few seconds, the lunch box begins to heat up. With the continuous discharge of steam, the hot pot can be finished in about 10 minutes!

The self-heating packaging of self-heating food will heat up immediately within 3 to 5 seconds after encountering water. After heating, it can reach above 150℃, and the steam temperature can reach 200℃, which is very easy to cause burns. If the ventilation is not good, it will cause an explosion. However, insufficient combustion of coke powder, activated carbon and other substances in the heating package will produce carbon monoxide.

Is it safe to eat self-heating hot pot?

When the self-heating wok is heated, the highest temperature of the parts that consumers can easily touch is generally above 70 degrees, or even above 90 degrees. However, some samples not only have no heat insulation design, but also the packaging will be deformed, which has potential safety hazards. Specifically, six samples at the bottom of the wok were deformed to varying degrees, among which the nominal brands were Kakasha Moxiaoxian, Shu Girl, Laocheng Nanshijia, Spicy Hot Pot, Runcheng and Baicaowei.

Self-heating hotpot principle

Self-heating packages have different formulations, but generally include four components, the most important of which is calcium oxide, which can generate hydrated lime after contacting with water, and its scientific name is calcium hydroxide. In this process, a lot of heat will be released, which is the main heat source of the heating package.

How to eat self-heating hotpot safely

1, the water heated after the heating package reaction can not be used again, nor can it be used for washing hands or cleaning food;

2. Don't put it on ordinary glass, otherwise it may lead to broken glass;

3, be sure to open the vent to exhaust hot air, so as to avoid small explosion caused by excessive pressure in the box;

4. Try to put it on a horizontal surface to prevent hot water containing chemicals from overflowing;

5. The reactants used in the heating package are not environmentally friendly, so it is recommended to recycle them after cooling.
