1: Invention

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.

2: Pressure Cooker Retain More Vitamins and Nutrients

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.

3: Pressure Cooking Doesn’t Produce Acrylamide

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.

4: Bringing Pressure Cooker to Pressure Doesn’t Sterilize its contents

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.

5: Pressure Cookers Can Be Canners Too

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.
