All things are fried in one pot. Have you ever used an air fryer? Recently, the air fryer for small household appliances has been hot searched. Some media reported that experts do not recommend multiple use, because high temperature will produce carcinogens, which may not be healthy. However, some experts pointed out that as long as the temperature is high enough, even if the air fryer is not used, harmful substances may be produced. Dinggangqiang, director of the Institute of nutrition and health of the Chinese Center for Disease Control and prevention, said that the air fryer uses flowing air to heat food, so the temperature is very critical to whether food produces harmful substances. He suggested that consumers should choose the right temperature to cook food, so as not to produce substances harmful to health due to excessive temperature. It can be seen that the key to the problem lies not in the air fryer itself, but in the way the food is cooked. From the perspective of healthy diet, it should be advocated to eat less fried and barbecued food, but this is not necessarily related to using more or less air fryers. In fact, in recent years, the sales of air fryers have continued to rise. Statistics show that in the past three years, the sales volume of air fryers jumped from one million units to ten million units. On social media platforms, air fryer recipes can also be seen everywhere. How to choose and use air fryers to make them safer and healthier? When Xinhuanet interviewed relevant engineers of China Household Appliance Research Institute, it learned that the common air fryers in the market have a capacity of 2l-5l, and the control methods are basically divided into computer control and mechanical control, and their cooking effects are almost the same; The heating methods are divided into three types: spiral 360 ° hot air circulation, 360 ° hot air circulation and upper and lower hot air circulation. The spiral 360 ° hot air circulation heats the food relatively evenly and sells at a relatively high price; The inner tank of the fryer also has a variety of designs, including the design with air guide groove or the design with screw thread on the chassis, which can make the hot air circulation efficiency higher, so as to make the food heated more evenly and taste better. The engineer said that the safety performance should be put in the first place in the purchase of air fryers, and the products with 3C certification and ISO9002 international quality certification should be purchased. Secondly, we should pay attention to the thermal insulation performance and cooking performance of the product. Consumers should consider the capacity, control mode, cleaning difficulty and appearance of the fryer to select the appropriate product according to their own conditions. Compared with traditional cooking methods, air fryer has the advantages of high cooking efficiency and low oil consumption, which helps to reduce oil intake. However, it should be noted that high-temperature cooking may produce harmful substances. The dietary guidelines for Chinese residents 2022 suggests that steaming, boiling and frying should be used more than frying and frying, which is more conducive to human health. (Xinhua News Agency)
