1. All kinds of high-temperature resistant containers can be used in the optical wave furnace, but if microwave cooking power is selected, it is best not to use metal or metal containers. Because metal can reflect microwave, it not only makes food difficult to cook, but also damages the parts of microwave oven and affects its service life.

If you cook frozen food, thaw it first. Attention should be paid to when thawing:

(1) thaw evenly with microwave low-power gear;

(2) For some foods with different thicknesses, in order to prevent a certain part from being cooked, first stop thawing, wrap the thin part with aluminum foil paper, and then continue thawing;

③ The food thawed at one time should not be too much or too thick. The thickness of meat food should not exceed 3 cm, and the thickness of other foods should not exceed 5 to 7 cm.

3. Avoid heating sealed canned food and bagged food with microwave oven, which may easily lead to explosion and rupture of sealed products, except for specially marked microwave food. If plastic wrap is added to the food container to prevent water evaporation, some small holes should be punched.

4. Avoid frying food in the microwave oven. Deep-fried food generally requires slow heating, while light wave and microwave heating speed is very fast, which is prone to danger.
