Why do purple potatoes explode when taken out of the oven, and what other foods are easy to "fry"?
Purple potato is a common food, and everyone likes it. It is not only nutritious, but also delicious. But many people put purple potatoes in the oven to roast and eat, or put them in the microwave oven to roast and eat, and suddenly they fry! After the case spread on the Internet, it also caused great shock and dissent! The reason for this is the following：
1, oven operation error.
Nowadays, it is very common for people to use ovens, but if they are not used properly, they may cause explosions. In the video, the explosion was caused by the wrong operation of the oven. When using the oven, the purple potato does not touch the air, but heats the gas through the contact between the heating tube and the food. Therefore, the purple potato will be exposed to air for too long, and air oxidation, cracking and deformation will occur.
2. The temperature of roasted purple potato is too high.
As we all know, the oven is a heating device, and purple potato is a kind of sweet potato, which must be cooked in a fixed place. If you put it in the oven and cook it before taking it out, it will take too long and the temperature will be too high. When sweet potato meat is deformed by heat, the internal structural pressure is too high and it is easy to explode. Someone bakes purple potatoes and cakes in the microwave oven. But sometimes people bake purple potatoes in the oven. Purple potato is too spicy. It is very likely that the potato meat tissue inside was not deformed by heat, and the steam inside exposed the working pressure, which led to the explosion accident.
3. Purple sweet potato is not completely cooked.
Uncooked purple potato In addition, we all know that food can't be completely cooked after cooking, or the temperature can't reach, which will also increase the risk of explosion. If at this time, someone puts the purple potato in the microwave oven for a while, but the temperature is not as strong as expected. At this time, purple potato may produce some harmful substances, and even pose a life threat to people. The above three points are all caused by the explosion of purple potatoes. Therefore, it is not possible to judge whether purple potato is suitable for baking only by continuous high temperature.
? 4. The baking time is too long.
The purple potatoes that are not fully cooked are taken out directly in the oven. If the purple sweet potato is baked in the oven for too long, the surface cells of the purple sweet potato are prone to chemical reaction and produce a lot of gas. This steam will continue to spread and cause an explosion! The above is about the cause of purple potato explosion. After watching this video, you should know that when this thing is baked in the oven, it is not convenient to heat it in the microwave oven! In that case, the somatic cells of purple sweet potato will be destroyed, and the gas inside will evaporate very easily!
