Matters needing attention in microwave oven heating rice
Not all utensils that can hold rice can be heated in the microwave oven. For example, plastic disposable tableware is not suitable for microwave heating, and neither is tin foil paper. You need to choose heat-resistant glass products, polypropylene plastics and ceramic utensils for heating. In addition, some foods with skin, such as potatoes and sausages, should be heated with toothpicks to avoid explosion caused by excessive pressure.
When heating things in a microwave oven, the utensils for holding food need to be non-metallic materials, such as glass, ceramics, high-temperature resistant plastics, etc. If you use metal utensils to store food, the metal utensils will reflect microwaves after being electrified, which will interfere with the normal C work in the microwave oven, produce high-frequency short waves and damage the microwave oven. Secondly, frozen food should not be directly heated by microwave oven.
Frozen food should be thawed first, then heated and cooked to avoid differences between cooked food and cooked food. Heat the food in the microwave oven. If you forget to take it out for more than 2 hours, you should discard it to avoid food poisoning.
