I firmly believe that many people who work can't do without the microwave oven, which is a kind of household appliance. In the morning, they can heat toast and sandwiches, and in the afternoon, they can heat their lunch. But, do you really use the microwave oven correctly? Today, everyone will talk about some basic application knowledge of microwave ovens.

Advantages of microwave oven.

Microwave cooking can preserve a lot of vitamins. Because microwave cooking has higher efficiency, shorter time and less water output, the damage of various vitamins is less than that of fried cooking and much less than that of stir-fried cooking under the condition that sterilization regulations are perfect or reached.

Microwave cooking can keep vegetables and fruits fresh. A scientific study on green asparagus can reveal this problem. In order to make canned asparagus better, several sterilization devices were designed, one is microwave cooling circulating water heating system software, the other is high-pressure water heating system software, and there is also general steam heating system software.

2. Defects of microwave oven

Microwave food is a chemical substance that causes carcinogens. Previous studies have shown that microwave-treated meat products will produce carcinogens; Carbohydrates in milk, fresh fruit and fruit cereal will also be converted into carcinogens after microwave; Green plant flavonoids in vegetables and fruits can also be converted into carcinogens after microwave, which is harmful to everyone's physical and mental health. The loss of food nutrition is serious.

The food cooked in microwave oven will greatly reduce the minerals, vitamins and nutrients in vegetables and fruits, or make them become carcinogens. The human body will secretly cause certain changes. Such as hormone imbalance, lymph node and digestive tract disorder, abnormal blood and immune ability, depression, memory loss, permanent brain damage, and even continue to cause heart disease.

Foods such as eggs and canned fruits should not be put into the microwave oven.

The basic principle of microwave heating is heating from outside to inside. When raw eggs are heated in the microwave oven, a lot of heat will be generated inside. This unreleased heat is easy to explode after reaching a certain working pressure. The most terrible thing is that the explosion of raw eggs is uncertain, which may be in the microwave oven or in your hand, as well as canned fruit, so people don't use the microwave oven to heat this food in daily application.

Do not heat metal utensils in the microwave oven.

The principle of microwave oven is to use the kinetic energy transmitted by radio waves to heat food, and radio waves will react with metal materials and cannot be digested, absorbed or transmitted at all, so food cannot be heated in metal utensils. In addition, metal materials will react when heated, which will destroy the microwave oven.

Food in a fresh-keeping bag

Fresh-keeping bag is a plastic product. Exposing the fresh-keeping bag to the high temperature natural environment of microwave oven will produce chemical reaction, which will cause safety hazard to the safety factor of food. Whether it is dissolved immediately or stuck to food, it is very inconvenient, especially after dissolution, it will continue to evaporate and choke the nose. In this case, the food is inedible.

Don't heat it for too long.

The microwave oven uses high frequency heating, and the heating speed is fast. If the time is too long, the food will become dry and hard, and even cause endotoxin. Therefore, in the specific application, it should be adjusted according to the development mode of food types. If the heating time is too long, it is likely to smoke at the bottom, leading to safety hazards.

Closed utensils are not allowed to enter the microwave oven.

The high temperature caused by microwave heating partly causes steam, which is high pressure. Once closed appliances are used, it is very likely to cause engineering blasting, so appliances with air holes must be used. This is why many lunch boxes have special air holes on them. It is recommended that you open the lid of the lunch box when heating.

The plastic box is heated in the microwave oven, and the PP5 logo is selected.

Not all plastic boxes can be heated in the microwave oven. Before heating, everyone must pay attention to whether there is a triangle sign on the bottom or side of the plastic bowl. The bottom data is 5 or the word PP, which means that polypropylene (PP) material can be heated in the microwave oven. It is suggested that you choose the PP5 logo when buying heated fast food boxes.
