With the continuous improvement of people's quality of life, microwave ovens have entered thousands of households. Many office workers also start to cook their own lunch after work. Eating lunch by yourself seems to have become an environmental trend for office workers. However, will microwave heating lose nutrition?
It is healthy to bring food to work without letting the microwave devour nutrition.
How big is the nutritional loss of microwave food?
It has been widely rumored that microwave food loses huge nutrition, which is harmful to health and easy to cause cancer. However, this statement was later proved to be a fallacy. Experts come to the conclusion that microwave heating food, although more or less will make the nutrition in food lose a little, is not so exaggerated and absolute. And when heating sweet potatoes and other foods, its nutrient loss components are far lower than traditional cooking methods. It seems that the nutrient loss of microwave food cannot be generalized, more or less depends on how you use the microwave oven.
Microwave heating food is very knowledgeable.
First, remember to keep moisture when heating the food.
Friends who have used microwave ovens to heat meals for a long time should have a deep understanding of this. After heating the slightly dry food in the microwave oven, it will only be drier than before. Yes, microwave ovens rely on the high-speed vibration of polar water molecules to increase the kinetic energy of molecules and raise the temperature. Therefore, when heating meals in the microwave oven, you must remember to keep moisture. The following two tricks teach you to easily prevent water loss:
1, food needs to be covered tightly before heating. If there is no bowl cover, it can be wrapped with plastic wrap and wrapped instead.
2. If your taste buds are not so picky, when heating rice, cakes or dishes, sprinkle some water on the surface and put it in the microwave oven. In this way, even if the microwave absorbs a certain amount of water, the remaining water still exists in the food.
Second, microwave heating depends on whose food is.
Some foods lose less nutrition when heated by microwave than traditional cooking methods, so food is very suitable for microwave. However, some foods are not optimistic after being heated in the microwave oven. I'll list some foods that are not suitable for microwave ovens:
1, don't cook raw eggs with shells and eggs with membranes.
Eggs with shells, or boiled eggs, are very unsuitable for microwave heating.
Let's not talk about the loss of nutrition. If eggs with shells or broken yolk are heated by microwave oven, it is easy to damage the microwave oven and even explode seriously, hurting people and themselves, and the consequences are unimaginable.
2. Fried food is not suitable for microwave heating.
Because this food has lost a lot of water in traditional cooking. If you "heat" in the microwave for a few more minutes, it will only "make matters worse" and there is no nutrition at all.
Don't heat food in a sealed bottle.
This food is too airtight. After overheating in the microwave oven, it will expand rapidly, which will lead to the failure of food flavor change and serious microwave oven explosion.
Third, microwave heating should grasp the temperature.
1, heating meat food
When heating meat, be sure to adjust the temperature to a little more than half a minute to a minute than ordinary food. This can completely heat the meat, kill the bacteria inside, and make the taste more delicate.
Step 2 heat vegetarian dishes
When heating vegetables and other materials, shorten the microwave oven time and turn down the heat, so that the heated vegetables will not be "yellow" like leftovers in a few days. It takes a little fire and a little time to keep vegetables fresh. In this way, the heated dish can be more "original |".
3. Heat liquids such as soup and porridge.
When heating this liquid, be sure not to spill the bowl surface. Almost enough. During this heating process, liquids such as soup will not overflow. If the liquid such as soup is not completely cooked after the first heating, you can gently stir it with a spoon and then put it in the microwave oven for the second time. Only in this way can it be safe and minimize nutrient loss.
In addition to the above-mentioned "microwave heating" trick, there is also a key point. When choosing lunch boxes, it is best to avoid using plastic lunch boxes, which are not environmentally friendly, difficult to clean and harmful to health. You can choose a glass lunch box for microwave ovens. In addition, I suggest eating a fresh fruit half an hour after eating microwave-heated food at noon every day, so as to keep moisture and health for a longer time!
