Pressure Canning In Your Presto
Pressure Canner
YourPressureCannerisaspecial,largecapacitypressurepandesignedforhomecanningawidevarietyoffruits,vegetables,meats,
poultry, and seafood.
TheCannerusespressuretoachievethehightemperaturesrequiredforsafelyprocessingfoodswhilecanning.TheUnitedStatesDepart-
mentofAgriculture,Washington,D.C.,recommendsthePressureCannerastheonlysafemethodforcanninglow-acidfoods—vegetables,
meats, poultry, and seafood.
Waterboilsat212°F(exceptinmountainousregions)andthistemperatureissufcienttoarrestordestroysomespoilageorganisms—
enzymes,molds,andyeast.However,atemperatureof240°Foraboveisneededtodestroyharmfulbacteria,especiallyClostridium
botulinum.
Inpressurecanning,someofthewaterintheCannerisconvertedintosteam.Afterallairisexhaustedthroughtheventpipeandautomatic
airventinthecover,thepressureregulatorisplacedontheventpipe.Expandingsteamraisestheautomaticairventandthencreates
pressurewithintheCanner.Asthepressureincreases,thetemperatureincreases:5poundspressure–228°F;10poundspressure–240°F;
15poundspressure–250°F.
As a safeguard against using canned foods which may be affected with spoilage that is not readily detected, it is necessary to boil all
low-acidfoods(allmeats,poultry,seafood,andvegetables)todetectanyodorsorfoamingfromspoilage.Ifthefooddoesnotsmellor
look right, discard it without tasting. Many times odors that cannot be detected in the cold product will become evident while heating.
To detect spoilage at altitudes below 1,000 feet, boil foods for 10 minutes. At altitudes above 1,000 feet, add an additional minute of
boiling time for each additional 1,000 feet.
ItisnecessarytofollowafewspecialrulesinusingandcaringforyourPressureCanner.Becomefamiliarwiththevariouspartsas
showninthediagramsandreadthe“HowtoUse”sectionbeforeusingforthersttime.UseonlygenuinePresto
replacement parts.
