If your summer
includes plans to can your home grown vegetables, I hope you also find time to
test your pressure canner dial gauge.
The pressure
canner is used to process foods under pressure at temperatures higher than
boiling. A pressure canner is the only safe method for processing low acid
foods such as vegetables, meat, poultry and fish. The pressure canner can
supply enough heat to destroy spores of bacteria that causes botulism as well
as other types of spoilage.
To have your
pressure canner tested, bring the canner lid to the Extension office located at
206 S. State Street in Decatur. The test
will help you determine the accuracy of your pressure canner and therefore be
confident in your ability to properly can food.
Pressure canners
with a dial gauge, should be checked once a year before the canning season.
Also check it during the season if you use the canner frequently. If you do not
have an instruction book for your canner, write for one.
The weighted
pressure control on canners does not need to be checked. Keep it clean and rust
free. In most canners there is a gasket. These gaskets are made of rubber or
rubber-like compounds to keep steam from leaking out around the cover. You can
remove and replace most gaskets as needed. Some only need to be turned to
ensure a tight seal. Replace a worn, stretched or hardened gasket with a new
one. Refer to the canner instructions for directions.
