MANTTRA SMART PRESSURE COOKER is brought to you by MANTTRA INC.
PRINCIPLE OF PRESSURE COOKING:
Under normal circumstances, most foods cook at 212
0
F ( 100
0
C). This is because the water boils at this temperature
in normal atmospheric pressure.
If the temperature of cooking is raised, foods cook much faster. For example, an increase of 32
0
F (18
0
C)
temperature allows food to be cooked four times faster, retaining freshness and nutritional values of the food.
By increasing the steam pressure inside a pressure cooker to 12 lbs per square inch above the atmospheric
pressure, the temperature inside the pressure cooker increases by 32
0
F (18
0
C) roughly. Thus, at these higher
temperatures food cooks much faster.
This is the principle of pressure cooking.
