Many Options for Preserving Tomatoes:
• Water Bath Canning• Pressure Canning• Freezing• Drying
Tomato Acidity Varies
• Type of tomato• Conditions during the
growing season• Soil in which the
plants are grown
Tomatoes
Other Factors that Affect Tomato
Acidity• Tomato juices are less acidic
than tomato solids• Over-ripe tomatoes will
decrease overall acidity• Adding low-acid ingredients
will decrease acidity• Canning itself can decrease
acidity
All Tomatoes are not Created Equal..
• Don’t can over-ripe, damaged or decayed tomatoes
• Don’t can tomatoes exposed to frost or harvested from frost-killed vines
• Don’t can late season tomatoes ripened indoors
Add acid to all canned tomatoes!
How much acid do I add?
Citric Acid Little change in flavor
½ teaspoon per quart
Bottled Lemon Juice
Easy to use 2 Tablespoons per quart
Vinegar (5% acidity) - only if called for in recipe
Noticeable change in flavor
4 Tablespoons per quart
Hints for a Safe, High Quality Tomato Product
• Process using the hot-pack method
• Consider processing tomatoes separately from low-acid ingredients
• Add meat only where directed• Don’t thicken tomato products
before processing
