Baking food in a household oven, the temperature is too high to roast carcinogens
The household items in the citizen's kitchen are becoming more and more "foreign". Many people have added ovens to roast meat and bake snacks. The exotic tastes are really different from traditional Chinese food. But when oven food is popular, how many people are concerned about the health problems related to it? The reporter asked the experts: The food baked in the oven can be very healthy, or it may contain a lot of carcinogens. The key is whether you can use it.
Oven cooking destroys vitamins and has no effect on meat nutrition
Ovens, microwave ovens, most families have these two kinds of imported cooking utensils, which one can better preserve the nutrition of food? After the evaluation of nutrition experts, the oven is slightly inferior.
"From the perspective of the degree of nutrient retention of food, the microwave oven is definitely better. This is related to its heating principle." said Han Lei, director of the nutrition department of the Youth Medical Affiliated Hospital. The microwave oven generates heat by rapidly moving food molecules inside. , So nutrition is not easy to lose. The oven is different. It heats the food from the outside to the inside, which will destroy part of the nutrition.
Although the oven was defeated in the PK with the microwave oven, Director Han said that as long as the oven is used correctly to prepare food, it is still much better than charcoal grilled food! Although the oven will destroy part of the water-soluble vitamins when roasting vegetables, if it is roasted, it will not have much effect.
This is good news for people who like to eat barbecue.
Baked food over 200℃ is easy to produce a lot of carcinogens
Roasting meat in the oven is healthier than charcoal barbecue. This makes people who can't live without beer barbecue in summer a little excited. However, it is also conditional to roast the roasted meat in the oven to be healthy-when setting the temperature, it is best not to exceed 200 ℃!
Director Han Lei told reporters that when the oven temperature is set below 200°C, as long as it does not bake, the baked food may be destroyed except for vitamins, and other nutrients are still well preserved, and it will not. What toxins are produced. Once the oven temperature exceeds 200°C, heterocyclic amines, benzopyrene and other carcinogens are easily produced in the food, especially the food that is baked to the burnt aroma!
The reason why oven roasts can be healthier than charcoal roasts is because the temperature of the oven can be accurately controlled, but the charcoal roasting temperature is not so easy to master.
Many western-style oven foods require a high temperature of 200℃
Is it difficult to bake food in the oven at a temperature not exceeding 200°C? Are there many foods that need to be set above 200°C during baking? The reporter looked through several highly sought-after food blogs, and found that there are a lot of foods that need to be baked at a temperature of more than 200℃——
Puffs, bacon and shrimp rolls: baked at 200°C for 12-15 minutes; pizza: baked at 200°C for 20-25 minutes; grilled cuttlefish: baked at 200°C for 10 minutes, brushed with sauce and baked for 5 minutes; barbecued pork: 200°C first Bake for 25-30 minutes; brush the sauce and continue to bake for 30 minutes; lamb chops: roast at 200°C for about 40 minutes; cheese chicken spaghetti, dried meat, saury: roast at 220°C for about 15 minutes...
Look, desserts, meat, seafood, etc., may all need to be baked at a high temperature of 200 ℃ or more, and some of them are baked at a long time!
Weapon: The meat can be roasted at low temperature for a while and try to refuse high-temperature desserts
There are so many foods that need to be baked at a high temperature above 200°C, but it is easy to produce carcinogens. What should I do? Can it be baked at a temperature of less than 200℃?
On this issue, the reporter interviewed Li Weiguo, head chef of the dim sum at Shangri-La Hotel, Qingdao. He said that if it is meat, turn down the baking temperature, and by extending the baking time, you can still bake delicious food, although the texture and taste may be a little bit compared to the original high-temperature baking. Is different, but the impact is not significant. But this method does not work for baked desserts-desserts require more precise baking temperature, with a little deviation, the taste and color of desserts can be greatly changed, so everyone should try to choose desserts with a baking temperature below 200 ℃.
