Of course you can, but you'd rather soak it in boiling water than microwave it, it's very un-nutritious.

The working principle of the microwave oven is to use water molecules to heat the food at high speed, which is similar to the hot pot to heat the food (water molecules in the food + heat conduction), but the microwave oven's water molecules are quite violent enough to destroy the protein and vitamin nutrients, which is the microwave oven, although convenient, but the reason why it is not popular, the microwave oven is more than used to heat some of the nutrients of the food or protein

In addition, the microwave oven can not heat metal objects, metal is known to have electromagnetic shielding effect, electromagnetic waves in the metal outer layer will cause electromagnetic discharge arc on the electromagnetic furnace has great damage.
