Excuse me, the heating principle and its harm to people.
Self-heating rice has a heating bag, and the temperature rises immediately within 3-5 seconds after encountering water. The temperature is as high as 150℃, the steam temperature is 200℃, and the heat preservation time can be up to 3 hours, so it is easy to make raw rice into cooked rice. The heating process has no pollution, low cost and no potential safety hazard.

Self-heating rice analysis chart

It is understood that traditional convenience foods need to be soaked in boiling water before they can be eaten. Some special people, such as field exploration, tourism, troops and police officers performing tasks, cannot eat without boiling water. Instant rice can be eaten by adding a part of water into the packaging box, tearing the outer packaging, pulling the drawstring, automatically mixing and heating the water with the heating bag, and heating or cooking the rice. Self-heated rice is actually very expensive, which has no price advantage compared with mainstream convenience foods, and there is no unified quality standard for this product in China now! The products on the market can be said to be mixed. It is hoped that relevant departments will introduce corresponding measures as soon as possible to inspect and approve the manufacturers of such products one by one, so as to protect consumers' rights and interests as soon as possible! Nowadays, many small factories attract investors' attention with low prices under the signboard of self-heating rice. Those quotations don't match the cost at all, and the purpose is to defraud investors of regional agency fees! Please keep your eyes open and beware of being cheated!
