[Review] Microwave heating food is simple and convenient, but improper use can also cause food safety problems. First of all, different food heating times are different, and secondly, not all foods are suitable for heating.
Heating food in a microwave oven is already a method almost used by every family in urban life. This method of heating food is quick and easy, but there are many things to notice. Today, let us introduce what foods cannot be heated in a microwave oven. Don't miss it.
Microwave oven heating time
Poultry: Add a little vinegar, white wine, or beer when heated to keep the food fresh and delicious. At the same time keep its own fresh and delicious. The heating time should not exceed 8 minutes. Otherwise, the nutritional value of the food itself is lost and the original color and flavor of the food can still be maintained. The best leftovers are up to one day, otherwise they contain nitrites that have a carcinogenic effect on the human body!
Seafood: Add seasoning when heating, such as onion, wine, ginger, etc., not only to mention fresh, but also a certain degree of disinfection and sterilization. Do not heat more than 6 minutes. Fish, heated for 5 minutes, heating for a long time, the protein contained in fish, fish fat and vitamins and other nutrients will lose their nutritional value. And the fresh taste of fish can also be destroyed.
Ordinary meals: Generally, they must be heated to 100 degrees or more for at least 5 minutes to kill ordinary bacteria in the meals. If they still need to be stored, they can be kept for a long time, but it is best not to leave the leftovers. Leftovers heat many times and lose many nutrients.
Next, come to understand what is wrong with microwave heating food.
Misunderstanding of Microwave Heating Food
Cooking containers: Maybe you are accustomed to throwing packaged foods together with plastic lunch boxes into microwave ovens. This is absolutely negligible. Because plastic containers can be deformed during heating and emit toxic substances to contaminate food, cancer will continue to develop in the long run.
Heating time: People often put food in microwave ovens to thaw or heat, and sometimes forget to take it out, for a few hours. If you forget to remove it for more than 3 hours, it is best to throw it away so as not to cause food poisoning. In addition, foods that have been heated for a long time tend to dry out due to rapid water loss. In addition to poor taste, the nutritional value will be greatly reduced.
When freezing or heating: The half-cooked meat is heated in the microwave until it is fully cooked. Although the cooking time can be shortened, the bacteria will still grow when the food is half-cooked. When the microwave is used again for the second time, the time is too short to be possible. All bacteria kill. When this happens, the frozen meat products can be thawed in a microwave oven and then cooked to a cooked food so that they can be safely consumed.
The heated food is contraindicated: It is best not to use fried foods in microwave ovens because high temperatures can cause splashes of oil and lead to fire. If the fire in the furnace does not open the door of the microwave oven, it should be cut off before the fire goes out. Open the door again. In addition, when cooking shelled food, shells should be punctured to avoid explosion.
Misplacement of placement: Since the microwave oven has radiation, do not put it in the bedroom. It should be placed in a ventilated place. And also to leave the TV and radio a certain distance, otherwise it will affect the audio-visual effects. After opening the micro furnace, it is best to maintain a distance of 1 meter from it, and do not look directly at the eyes. Otherwise it will cause dizziness, dizziness, fatigue, weight loss, hair loss and other symptoms.
In the end, we also counted the foods that could not be heated by microwave ovens and continued to learn more about them.
Which foods cannot be heated in the microwave
asparagus. Fresh asparagus is rich in many antioxidant nutrients including vitamin C. A new study published in the Scandinavian Journal of Agriculture in Norway found that microwave heating causes loss of vitamins in asparagus. Because vitamin C and B vitamins are water-soluble vitamins, their stability is even worse, and they are vulnerable to water, heat and light.
Breast milk. Many mothers squeeze breastmilk into a bottle, store it in a refrigerator, and heat it in a microwave oven when used. This can easily lead to a reduction in important nutrients. A study published in the American Journal of Pediatrics found that the risk of E. coli in breastmilk-heated breast milk is 18 times higher than in other methods.
broccoli. Broccoli is the most common microwave food. However, a study published in the United States "Science Journal of Food and Agriculture" found that cooking broccoli in microwave ovens resulted in a reduction of 97% in antioxidants. Cooking broccoli with a gas stove only results in a reduction of 11% in antioxidants.
Dry chili peppers. Capsaicin in dried peppers is volatile and unstable, and microwave heating can easily catch fire. During microwave heating, chemicals emitted from dry peppers can irritate eyes and lice.
Frozen fruit. A study published in the American Journal of Biomagnetism found that thawing frozen fruits in microwave ovens can easily lead to the conversion of healthy glucosides and galactosides into carcinogens. The best method for thawing frozen fruits is natural thaw at room temperature.
garlic. A study published in the American Journal of Nutrition found that heating a microwave oven for 1 minute will destroy the active thioallyl compounds in garlic and cause it to lose its anticancer effect. Most of the vegetables, especially green leafy vegetables, may be subject to excessive nutrient loss if they are heated in a microwave oven, because nutrients such as vitamin C in vegetables are sensitive to light and heat. However, microwave heating of meat, eggs, and staple foods results in less nutrient loss.
The method of using microwaves to heat food must be correct.
