News from our newspaper (Reporter Liu Bo) "Self-heating food" such as self-heating hot pot and self-heating rice has been favored by many people after becoming Internet celebrity food.

Wang Xin, a public nutritionist in this city, reminded that self-heating food is instant food, which is convenient to eat, but has a certain loss of nutrients. Improper use of self-heating packs for heating also has certain safety hazards.

It is recommended not to eat "self-heating food" for a long time, and pay attention to nutritional matching when eating, and use heating packs correctly.

  At present, self-heating foods on the market mainly refer to prepackaged foods that are heated by heating packs without relying on electricity or fire.

Before eating, put the self-heating pack at the bottom of the food box, add cold water, and wait for ten minutes to make steaming food.

Self-heating food is very convenient, and it has become the choice of many people when they travel on business, play outdoors, work overtime and have a late night snack, and are unwilling to cook.

When purchasing, choose products from regular manufacturers, observe whether the outer packaging is complete and undamaged, and whether various labels are clear and clear, and do not buy products with incomplete label information.

At the same time, pay attention to the shelf life of such products and should not be stored for too long.

  From a nutritional point of view, most self-heating foods are heavy in taste, high in sodium content, high in calories, and uneven in nutrition. Moreover, various ingredients will lose nutrients to varying degrees during processing, and there are many food additives.

The reason why the rice in self-heating rice can be cooked quickly is because the rice has been processed in advance, it belongs to remodeled rice, and it is not the rice that is often eaten in daily life, so its taste is different from ordinary rice. Nutrients are also lost.

Therefore, self-heating food can be eaten as short-term emergency food, and long-term consumption is not recommended.

When eating, you can match some fresh vegetables and fruits to ensure a balanced nutrition.

  The heating pack in self-heating food is mainly composed of iron powder, aluminum powder, coke, activated carbon, quicklime and other materials.

After a chemical reaction, it can heat up quickly, and it is easy to heat and cook the ingredients in the package.

Before using the heating pack, you should read the usage and precautions on the package, standardize the operation, and be careful not to add hot water or block the air outlet on the top of the box.

Special attention should be paid to the fact that the heating pack cannot be eaten. Do not let children tear or even eat the ingredients in the heating pack by mistake, so as not to stimulate or even burn the mouth and digestive tract.

If you find that there is powder leakage from the heating pack, do not continue to use it.

It is best to heat the packaging of self-heating food on a heat insulating pad, not on glass, plastic and other countertops.

During the heating process, the temperature of the heating package can reach over 150°C, and the temperature of the steam can reach 200°C, so do not touch the box body with your hands and do not get close to the steam, otherwise accidental injuries such as burns will easily occur.

The used heating pack will harden and can be disposed of as hazardous waste.

Discard the remaining water after heating, do not reuse it, let alone drink it.
