Know Your Freezer Facts

Freezing is easier than canning, but be sure you have a freezer that can hold the food safely.

  • Your refrigerator freezer is meant for short-term storage and small amounts of food.
  • Larger quantities should be kept in an upright or chest model freezer with enough space for foods to freeze quickly.
  • Check the temperature to make sure it’s below 10°F; 0°F is recommended. Frozen foods can be kept at this temperature for eight to 12 months. 

Store Canned Foods Safely

Keep them in a cool, dry place – home-canned goods are stable for up to 12 months. Jar rings can be removed because the jar is sealed; this keeps them from rusting and makes them available for reuse.


Fun Facts About Canning

Developed as a way for the French military to preserve food during the Napoleonic Wars, “canning” was initially done using glass jars. Since glass didn’t travel well, jars were replaced by metal cans.  Unfortunately, can openers weren’t invented for another 30 years, so soldiers had to open cans by cutting them with bayonets or smashing them with rocks!

Today, home canning involves heating the contents of a jar to a high enough temperature to kill any bacteria inside. It also creates a positive pressure that forces out air and creates a tight seal as the jar cools. With the removal of oxygen, vitamins and minerals in the food are preserved – ready for your enjoyment any time.
