Pressure cooker is made of stainless steel, because it is durable, has longer service life and is not easy to be decomposed.
When we buy pressure cooker, we often hesitate between stainless steel pressure cooker and aluminum alloy pressure cooker. Which one is better?
In contrast, stainless steel pressure cooker is better. First of all, in terms of service life, the service life of stainless steel under high pressure is longer.
Secondly, from the perspective of health, aluminum is easy to increase the aluminum content of food materials during cooking, although there is an oxide layer outside the current aluminum alloy pressure cooker to prevent this from happening.
However, the oxide layer may be damaged, while the stainless steel pressure cooker will not have such trouble.
