1. Do not overheat. The food is thawed or heated in a microwave oven. If you forget to remove it, if it takes more than 2 hours, you should discard it so as not to cause food poisoning. Microwave oven heating time depends on the material and the amount, but also with the freshness of food, water content. Since various foods are heated for different times, it is advisable to use a shorter time when the heating time required for the food is not certain. After the heating, the heating time can be determined based on the raw and cooked food. Otherwise, if the time is too long, the food will become hard, lose its flavor, color, taste, and even produce toxins. According to the type of food and cooking requirements, adjust the timing and power (temperature) knob, you can read the instructions carefully to understand.
2. Do not use ordinary plastic containers. First, hot foods can deform plastic containers. Second, ordinary plastics release toxic substances, contaminate food, and endanger human health.
3. Do not use metalware. Because of the iron, aluminum, stainless steel, enamel and other utensils placed in the oven, microwave ovens generate electric sparks and reflect microwaves when heated, which not only damages the furnace but also does not heat the food. Do not use closed containers: Wide-mouth containers should be used when heating liquids, because the heat generated by the heating of food in closed containers is not easily dissipated, and the pressure in the container is too high, which can easily cause blasting accidents.
