Question

What is the principle used in a pressure cooker?

Answer 1

• Pressure cooking is the process of cooking food under high-pressure steam, employing water or a water-based cooking liquid, in a sealed vessel known as a pressure cooker.
• The principle used in the pressure cooker is that the boiling point of water increases with the increase in pressure.
• The steam builds up inside a sealed cooked pot, which increases the ‘boiling point’ of the water trapped inside.
• The increase in pressure in turn raises the boiling point of water, which normally limits the cooking temperature of wet foods to 100°C.
• High pressure creates higher cooking temperatures and helps cook food faster and quickly.
