Pressure cookers are a few hundred years old, but they have become a popular means of cooking in households. The first ever pressure cooker was invented about four centuries back. Although at that time people preferred the traditional methods of cooking. However, with time, especially in the 20th century, pressure cookers gained much popularity. Today, there isn’t a kitchen without a pressure cooker. This appliance proved to be very helpful in cooking the food fast as compared to regular cooking. It stores the steam inside that prevents it from vaporizing into the atmosphere, thus causing the food to boil in less time.
With the advent of this smart kitchen appliance, there was a big argument that whether or not pressure cooking is healthy for the human body. Anyhow, with time, science finally proved that pressure cookers preserve nutrients by using less water, thus, they provide you with more healthy food that is rich in nutrients and other vitamins. Well, that being said; here are eight interesting facts about pressure cookers you didn’t know so far. I’m quite sure these facts will amaze you!
The first ever pressure cooker was invented in May 1689 by Denis Papin. Denis was a French physicist. He demonstrated his invention “STEAM DIGESTOR” at the Royal Society in London for cooking bones. Initially, the appliance was termed as a steam DIGESTOR, and if we ever had a chance of seeing that object now, we may not recognize it. Of course, people at that time lagged technological advancement. Today, we even have some latest pressure cookers with a digital control panel and many other functions.
Researchers have proved that pressure cooking retains more nutrients and vitamins from vegetables and meat as compared to boiling or steaming. When the pressure cooker is running, much of the steam generated remains inside the container. This steam converts into liquid containing the nutrients and vitamins. In this ways, it is retained back into the food.
When you cook starchy foods like potatoes at temperature above 120 Degree Celsius, it produces carcinogenic compounds. Cooking in pressure cooker can easily go beyond this temperature, however; it doesn’t produce any acrylamides due to the pressure cooker’s moist environment. So, you always get safe, healthy and delicious food.
The pressure cooker is so manufactured that it possess the ability to sterilize. But this requires time! To achieve the clinical sterilization, you have to run a pressure cooker to 15 PSI for about 30 minutes. In case you have an electric pressure cooker, that does not reach 15PSI, will require more time to get sterilized.
Well, if you didn’t know about this, then let me tell you that there are a lot of pressure cookers that can be used as a canner. Such pressure cookers have the ability to process up to 5 quarts jars at a time. These are the multi-purpose pressure cookers, and handy as well.
6: You Can Cook Anything
Pressure cookers are such an appliance in which you can cook nearly any type of food. Whether it be a vegetable, piece of meat or even pork. You can also boil rice, beans, corn, etc. However, when cooking any food, you have to be careful about the quantity of water required. If you pour in too much water, it may spoil the taste. On the contrary, if the amount of water is less, you may end up with a burnt piece of meat.
7: Old Pressure Cookers Are At A Risk Of Exploding
It has been found that pressure cookers that are over five years old are at a high risk to explode. The metal that is interlocking the lid and deals with the pressure inside the chamber becomes weak over the time. The three four main parts of a pressure cooker, rubber ring, pressure indicator and rubber overpressure plug are responsible for maintaining a safe level of pressure inside the chamber. Of course, as any other appliance would malfunction after several years, these parts of the pressure cooker also become weak. So, you should consider changing your pressure cooker as soon as it’s four years old.
8: The Plastic Handle Of Pressure Cooker Doesn’t Melt! Why?
The plastic that is used in the handle of the pressure cooker is made from thermoset material. This material has a very high melting point. Even if you run the pressure cooker for more than 2 hours, this plastic handle would still not melt. Another plastic known as thermoplast was used several years before, but due to its low melting point, it easy melts. This was then replaced with the thermoset plastic.
