Microwave oven is the principle of magnetic **** vibration, so that the water molecules inside the heated object collide with each other to generate heat, but the temperature is high water molecules will evaporate, so the steamed bread bread can only be heated once, the second time, it will be hard as a rock.

Food to maintain the fluffy material, must maintain two elements. Moisture and structure. As microwave treatment is good, the structure is certainly not a big change, but because there is no locking moisture, so it is easy to become hard. Therefore, the patented core of the steamed bread machine also lies in the locking of moisture.

How to make the steamed buns, cakes in the microwave heating will not become hard? Put the buns in a container with a lid before putting them in the microwave, so that you can reduce the loss of water in the buns; or add a small amount of water to the container, so that the buns will be more fluffy after heating, but be careful that you still need to cover the lid.
