What is the principle of air fryer? Is it good for health? In daily life, people will use all kinds of household appliances to help cook all kinds of delicious food. In recent two years, air fryers have been selling well in the market. The following is the principle of air fryer. What is good for your health?

What is the principle of air fryer? Is it good for health? 1 The working principle of the air fryer is that the internal air in the enclosed space is heated rapidly by baking, and then the hot air in the food basket is circulated rapidly by a high-power fan. On the inner side of the food basket, there are special lines, which can make the hot air form a vortex hot air flow, thus heating the food surface in an all-round way and quickly taking away the water vapor generated by heating. The three functions work together to make food dehydrated, golden and crisp.

Using this working principle, the air fryer does not need much oil to fry food. For some heavy oil foods, you can not fry them, which is healthier than traditional fried foods. It can reduce people's oil intake, but because the food fried by the air fryer is also treated at high temperature for a long time, it will reduce many vitamins in the food, thus reducing many nutritional values. Eating food fried in an air fryer for a long time is not good for your health.

It is suggested that people who love fried food should eat less even if they use air fryer, occasionally, but not often for a long time, otherwise it may affect their health.

Food that can be made with an air fryer.

1, can make all kinds of delicious food, such as French fries, potatoes, snacks, meat and poultry. You can also use it as a pre-dinner snack and bake hard chocolate in it.

2. Vegetables that can be barbecued, such as pumpkin, corncob or pepper, can be made in a frying pan. Vegetables usually used for cooking, such as carrots, broccoli and beans, cannot be made.

3. Frozen raw materials and fresh raw materials can be made. When frying frozen food with air, there is no need to thaw it. The most suitable setting can be selected by the temperature knob.

4. Two different raw materials can be made in the air wok at the same time. Just put the partition board in the frying column, and then put different ingredients on each side, such as chicken legs on one side and potato chips on the other. Ensure that the production temperatures of different raw materials match.

What is the principle of air fryer? Air fryer uses heat energy to make food rotate at high speed in a closed system and expand it. It is essentially an oven, which blows heat to food through a fan, separates the fat of food through circulating hot air, and makes the food close to the taste of frying.

Does the food fried by the air fryer contain carcinogens? As a qualified health expert, you must do your homework before you start. It turns out!

Air fryer means that although I am a pot, I don't carry "this pot".

First of all, fried and grilled foods are due to cooking methods, so there is a high probability that some carcinogens will be produced.

According to the Korea Consumer Research Institute, even if cooking oil is not added, starch foods are easy to produce acrylamide when cooked at high temperature for a long time. However, the World Health Organization said that it is difficult to count the concentration of acrylamide causing cancer. So I suggest that you try to reduce the cooking methods of carcinogens.

Secondly, the air fryer that meets the national food safety standards is in contact with food under the recommended use conditions (key points), and the level of substances migrated into food will not endanger human health. At the same time, frying food with air fryer uses less oil and is healthier than traditional frying.

Is there a health risk if the coating of the ordinary non-stick pan liner directly touches food?

The most common non-stick coating material is PTFE. Non-stick coating usually has the characteristics of high temperature resistance, corrosion resistance, water resistance and oil resistance. Its advantages, as the name implies, are: first, food is not easy to adhere and easy to clean; Secondly, the cooking process produces relatively little oil smoke, which reduces the harm to health.

On the other hand, some perfluorinated compounds, such as perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), are often used as waterproof and oil-repellent additives in the production of non-stick coatings. Some of these substances are considered endocrine disruptors, suspected carcinogens and harmful to the immune system.

But, to the point! Compliance products that have passed the standard test of GB4806, 10 Coatings for Food Contact can be used with confidence.

If the coating falls off, will the heavy metals in the metal liner run into the food and cause harm to the body?

Considering the excellent price, light weight and good thermal conductivity, most manufacturers will choose aluminum as the liner substrate, and some will use stainless steel or other metal materials. From the point of view of health and safety, there are safety risks in the process of contact between the liner substrate and food. According to GB 4806 "Metal Materials and Products in Contact with Food", production enterprises should ensure that the content of harmful substances in metal substrates will not exceed the standard limit under normal use conditions.

It should be noted that the coated products often fall off, which may be caused by long-term use or high-temperature dry firing, or by incorrect cleaning methods. When the coating falls off, the substrate will be exposed. At this time, the aluminum substrate is not suitable for contact with acidic food, and the risk of harmful metals migrating to food is easy to occur during use.

What is the principle of air fryer? In recent two years, air fryers have been selling well in the market. Its working principle is very simple. There is a heating device inside to "bake" the food in the pot through hot air circulation. Because its propaganda language often contains "health" and "low oil", it conveys the idea that food and health can have both. In fact, it is unhealthy to eat food cooked by air fryer often.

The air fryer is known as "oil-free" or even "low in oil", but it is not necessary to put oil except pork belly, chicken wings, mutton and squid, which have high oil content. Take French fries as an example, French fries should be brushed with scallion oil and salt and pepper before entering the oven, and then baked for 15~20 minutes. French fries are very oily. Cooking without oil or with less oil will not taste and taste good.

Compared with ordinary frying, the fat content of food cooked in air fryer is indeed lower, but its heating temperature exceeds 120℃, mostly at 180℃~200℃, which will produce acrylamide, a suspected carcinogen. Eating this food for a long time is harmful to human body.

It should be reminded that no matter what cooking method, eating fried food in large quantities for a long time is not healthy, and it is best to stay away from this kind of food.

Cleaning suggestion

1, please make sure the power is turned off before cleaning.

2. Wipe the surface of the exposed part of the fryer with a rag dipped in detergent to remove oil stains and food residues.

3. The inside of the fryer can be cleaned with a soft rag, and must not be cleaned with a cleaning ball and a sharp brush to avoid damaging the non-stick coating on the surface.

If oil spills on the electric heating line, wait until the electric heating line is completely cooled, and then wipe it with a kitchen paper towel or a dry rag. If it sticks to food, first sweep it off with a soft brush and then wipe it clean with a rag. The iron brush may scrape off the paint on the heating wire, thus damaging the product. Please avoid using it. If there is still residual water on the heating line, it can be sucked up with kitchen paper towels.
