Microwave cooking is time-saving and labor-saving, and it has become a necessary kitchen item for office workers. However, when cooking food with microwave oven, it will lead to the loss of nutrients, and the minerals, vitamins and nutrients in food will be greatly reduced or converted into carcinogens.
It is strictly forbidden to heat sealed food in microwave oven, such as bagged, bottled and canned food, and food with shell and skin. It is necessary to use staged heating to help the food be heated evenly, which can preserve the nutrition of the food and avoid the concentration of heat and produce toxic substances during the heating process.
