If the pressure cooker is working properly, can I continue to use it?
Housewives usually don’t stop using the pressure cooker until it wears out completely. Some high-end pressure cookers have a long lifespan so you can expect to use them for many years. But the answer is no if it is really safe. Even though a pressure cooker may still work for years, small changes that are invisible to your eyes may actually have taken place inside the cooker. This can cause danger at unexpected times.
What to know about pressure cooker?
Pressure cookers are made of ordinary aluminum alloy metal. Nowadays, there are many varieties of stainless steel pressure cookers.
When cooking in a cooker the water inside is heated and eventually boils into steam. Steam cannot escape and collects above the food. These water molecules increase the pressure inside the cooker. Chemical reactions can then take place, breaking down the tissues in the food or softening the starches in vegetables. This performance may decrease with years of use.
In one study, a long-term test of 3000 pressure cookers showed that using a pressure cooker for 1 hour a day is good and its service should not exceed 8 years.
