What is canning and why is it important?

Canning, as we know, is a way of preserving food for longer life. In this process, the contents of the food are placed in an airtight container and then exposed to heat with the aim to destroy enzymes that can cause food spoilage. The heating process drives out the air from the jar and when it cools, it forms a vacuum seal, which prevents air with microorganisms from coming back into the jar.

Principles of canning

Raw rice need not be canned as any variety of this grain can last for more than five to six months. It is semi-boiled rice that requires canning.

Pre-preparation of Rice

  • Take two cups of rice and double the amount of water in a pan and add a pinch of salt into it.
  • Heat the pan with its ingredients without overcooking rice.
  • Remove from heat and let it cool on its own.
  • It is not recommended to pressure cook rice, as it will overcook it.
