McRibbons pans refer to cookware made of special coatings and aluminum alloys, which are not harmful for long-term use. However, buying fake products or using them improperly may cause the coating to fall off, which can be harmful to human health and lead to cell cancer in serious cases. In daily life, when a metal spatula or wire ball is used to scrape a rice cooker, the coating may fall off, or when the bottom of the pot is overheated to 350°C, the coating will decompose and release harmful substances into the food. If this situation exists for a long time, it may cause cell carcinogenesis and increase the cancer rate. Therefore, in order to avoid the above hazards, first of all, it is recommended that you buy from the regular manufacturers to avoid buying fake rice cookers. At the same time, it is recommended to use a wooden spatula, silicone spatula frying, avoid the use of shovels, steel wire balls, etc., and do not spend a long time burning the pot. After each use in time to clean, wipe dry water, keep the pot clean, and then put the pot in a dry place to store, to help extend the life of the pot. In addition, if the coating of the rice stone pot has fallen off, it is not recommended to continue using it.
