{9 99}

Since the principle of microwave furnace is to pass through microwave electric waves, the water molecules in the food will vibrate and rub and generate heat. After heating, the water in the food will become water vapor, and the internal pressure and body volume will gradually increase. The existence of the shell membrane will make the water vapor unable to dissipate, which may make the ingredients unable to withstand bursts and open. Therefore, none of them can be microwaved, such as crabs, eggs, chestnuts, etc. Can't microwave the egg and a whole whole cooked egg

The cushion used for adding a cushion must also be of microwaveable material.

2. The insulated film

will dissolve the plasticizer, and the insulated film must be removed before microwave.

3. The layered soft bag containing aluminum foil metal

microwaves will cause sparks and dangers. Be sure to pay attention to whether there is a word "microwaveable" before heating.

4. Paper box and paper bowl

need to depend on the material. If edible batter is heated and heated, it will easily dissolve. Plastic coatings with numbers 2, 4 and 7 are also not suitable for microwave heating.
