微波炉既快捷又方便,既经济又实惠,是现代快节奏生活的理想烹饪工具。但研究表明,微波食品对健康颇有危害。微波炉怎样烹饪食物微波是很短的电磁波,属于大自然能量光谱的一部分。太阳产生微波,但是,太阳产生的微波与微波炉产生的微波有重大区别。这个区别在于微波炉是用交流电来产生微波的。所有的电磁波每经过一次电波周期,就会从正极变为负极。交流电可以增快电波的周期。水分子有正极和负极,因此当水接受正负交替的微波能量时,水分子会迅速转动。这有点类似用磁石把平面上的大头针吸得团团转的情形。微波炉用交流电产生的微波使食物中的水分子以每秒钟几十亿次的速度旋转,造成分子之间巨大的摩擦力,使食物迅速加热。人们通常只关心微波炉是否存在微波泄漏的情况,以为微波食品本身是安全的。
Microwave oven is fast and convenient, economical and affordable, ideal for modern fast-paced cooking. However, research shows that microwave food is quite hazardous to health. How Microwave Cooks Food Microwaves are short electromagnetic waves that are part of the spectrum of nature’s energy. The sun produces microwaves, however, the microwaves produced by the sun and the microwaves produced by the microwaves are significantly different. The difference is that microwave ovens use alternating current to generate microwaves. All the electromagnetic waves change from positive to negative after every radio wave cycle. AC can speed up the cycle of the wave. Water molecules have a positive and a negative, so when the water accepts alternating positive and negative microwave energy, the water molecules will rotate rapidly. This is a bit similar to using a magnet to lift a pin on a flat surface. Microwave microwaves produced by alternating current microwaves in the food molecules in the billions of times per second speed of rotation, causing huge friction between molecules, so that the rapid heating of food. People are usually only concerned about the existence of microwave leakage of microwave ovens that microwave food itself is safe.
