Microwave ovens emit microwaves through magnetrons. Microwave is a kind of high-frequency electromagnetic wave with a frequency of 2450MHZ and strong penetration. It can penetrate plastic, glass, ceramics and food, and make the water molecules inside the food vibrate violently to generate heat, and both inside and outside the food generate heat at the same time, so the heating speed is very fast and the efficiency of converting electric energy into heat energy is very high.
Light wave is an electromagnetic wave with lower frequency than microwave. Optical wave oven is a kind of current that emits visible light, ultraviolet light and infrared light through electric heating elements (such as infrared bulbs and timely heating tubes) to irradiate the surface of food and heat it. Heat is gradually conducted from the outside to the inside of the irradiated food, so the heating speed is slow.
The efficiency of converting current into light waves is very low. Therefore, it takes longer to roast meat with the same power light wave than to heat it with microwave.
The correct way to barbecue in microwave oven is to use both microwave and light wave.
Barbecue secret recipe;
Secret recipe 1
Make good use of aluminum foil paper. Spreading a layer of aluminum foil paper on the baking net can prevent carcinogens from contacting food directly, and can also wrap food with aluminum foil paper before baking.
Secret recipe 2
Choose fresh ingredients. Nitrate and nitrite preservatives are often added to sausage, ham and other meat products. When this substance is combined with protein, it is easy to form nitroamine carcinogens. So, buy less of this processed or reprocessed food.
Secret recipe 3
Eat more antioxidant foods. Carcinogenic substances are easy to be produced in the barbecue process, which can be matched with foods containing antioxidant nutrients, such as vegetables rich in vitamin C and vitamin A, green peppers, carrots and onions can be used as mutton kebabs, and onions, garlic and ginger can be used in the pickling process for seasoning, and mushrooms such as mushrooms and shiitake mushrooms can also be used.
Secret recipe 4
Dilute the salt in barbecue sauce. If barbecue sauce is diluted or seasoned with water, such as adding lemon juice, minced garlic and mint leaves to soy sauce, it will not absorb too much salt.
