The food in a thermos flask generally does not cause cancer. When using it, attention should be paid to the hygiene of the flask, and it should be cleaned in time. Food can only be consumed after it is fully cooked. It is not advisable to use a thermos flask to prepare complementary food for babies, because the food made in a thermos flask is not easy to digest and may easily lead to indigestion for babies.
1. First of all, there is no harm in a thermos flask, and people's claim that eating from a thermos flask can cause cancer is unfounded. Don't worry about it. Secondly, if there are other cooking tools available in daily life, it is best not to use a thermos flask, because the pressure of a thermos flask is limited and it is difficult to cook food thoroughly, which may easily affect physical health.
2. A thermos flask is a cooking utensil that integrates multiple functions such as stewing, braising, simmering, cooking, heat preservation, cold preservation, and portability. It has the characteristics of safety, energy conservation, and environmental protection. After putting food in, as long as the process of simmering does not emit steam or evaporate, the nutritional value of the food can be preserved, and the food can be stored for more than 6 hours with good results.
3. The working principle of a thermos flask lies in its material: its high-vacuum heat insulation technology can maximize the blocking of heat radiation, convection, and conduction in an environment similar to a vacuum, allowing food to slowly cook in a state of nearly zero heat loss. In simpler terms, it is like a large thermos flask that cooks food through stored heat.
