1微波炉加热的食品会致癌吗微波加热是依靠物体吸收微波将其转换成热能的加热方式,是物理加热,不发生分子结构改变,正常使用对人体无害。食物由水、脂肪、蛋白质、维生素等物质组成,食物中的水,在吸收了微波能量后,发生高速旋转振动,从而相互摩擦产生热量使水温升高,食品的温度也随之升高。微波炉发出的微波频率一般是2.45GHz,也就是说食物中分子每秒振动24.5亿次,在短时间内产生足够的热量,但其
1 Microwave heating of food will cause cancer? Microwave heating is to rely on the object to absorb microwave heating into heat, is a physical heating, molecular structure changes do not occur, the normal use of harmless to the human body. Food consists of water, fat, protein, vitamins and other substances, water in food, after absorbing the microwave energy, high-speed rotating vibration occurs, which friction heat each other so that the water temperature, the food temperature also increases. The frequency of microwaves emitted by a microwave oven is generally 2.45 GHz, meaning that molecules in food vibrate 2.45 billion times per second and generate enough heat in a short time,
