Question

Why are oil and fat containing food items flushed with nitrogen? Q19: What is electrical power? Write its unit.

Answer 1

Oil and fat containing food materials get oxidised when kept open for a long time. They become rancid and their smell and taste change. Nitrogen is an inert gas. So, oil and fat containing food materials are flushed with Nitrogen to prevent them from getting oxidized.


Electrical power is the rate, per unit time at which electrical energy is transferred by an electric circuit.
Its SI unit is watt.
