Home canning tomatoes is a excellent way to enjoy your harvest long after the growing season is done. Processing times and instructions have been scientifically determined to ensure safe products free of molds, yeasts, and bacteria. It is extremely important to follow the tested recipes for canning tomatoes and tomato products.
Tomato Selection and Preparation | Steps for Canning Tomatoes | Recipes for Canning
Tomato Selection and Preparation
- Select disease-free, preferably vine-ripened, firm tomatoes for canning. Do not home can over-ripe tomatoes or those from dead or frost-killed vines. These will result in a poor quality and a potentially unsafe canned product. Green tomatoes are more acidic than ripened fruit and can be canned safely with any recommendation in this publication.
- For nine pints of canned tomato products, 13-14 pounds of tomatoes are required. Approximately 23 pounds are needed for seven quarts of canned product.
- To prepare fruit, wash, remove stems, and trim bruised or discolored portions. To remove the peel, dip tomatoes in boiling water for 30 to 60 seconds until skins split. Dip into cold water, slip off skins and remove the cores.
- Tomatoes can be canned with or without salt. Salt seasons the product but is not necessary for a safely canned food. If salt is desired, add ½ teaspoon to pints or 1 teaspoon to quarts before placing the lid on the jar. Add salt substitutes, if desired, when serving.
- A commercially produced seasoning packet intended for home canning can be used but the directions and ingredients should not be changed as this may result in a potentially unsafe canned product.
Steps for Canning Tomatoes Safely
New to canning or need a refresher? Let's Preserve: Canning Basics, provides information on the basics of canning such as the different methods of canning, jar and lid selection, preparation, filling and processing steps.
Methods of Processing for Tomatoes
- Tomatoes can be safely processed in a boiling-water canner, steam canner or pressure canner.
- The atmospheric steam canner is fairly new to home canning. It uses only 2 quarts of water (compared to 16 quarts, or more, in a boiling-water canner). Because less water is heated, processing can start more quickly. Process time is based on the recommended time for a boiling-water canner. Processing time in a steam canner is limited to 45 minutes or less, including any modification for elevation.
- Tomatoes and tomato products processed using a pressure canner will often result in higher quality canned tomato products.
- Tomato-vegetable mixtures such as spaghetti sauce must be processed in a pressure canner. It is not safe to increase the portions of vegetables such as onions, celery, peppers or mushrooms from tested recipes.
Adding an Acid
- A high acid level (pH of 4.6 or less) prevents the growth of Clostridium botulinum bacteria which causes botulism.
- Tomatoes usually are considered an acidic food, although some varieties may have pH values above 4.6. Additional acid such as lemon juice must be added to boiling-water canning, steam canning and pressure canner options to ensure a safe product.
- Treat heirloom tomato varieties the same as any other tomato. The acidity of heirloom tomatoes is no different from the non-heirloom varieties. The same acidification recommendations apply for canning heirloom tomatoes.
- To ensure proper acidity in tomatoes, add one of the following acids directly to each jar before filling with product:
Acid | Pints | Quarts |
---|---|---|
Bottled lemon juice | 1 tablespoon | 2 tablespoons |
Citric acid | ¼ teaspoon | ½ teaspoon |
Vinegar (5% acidity) | 2 tablespoons | 4 tablespoons |
- When using lemon juice, use only commercially bottled juice. There is an industry standard for bottled lemon and lime juice, which ensures accurate and consistent acidification. The acidity of freshly squeezed lemons and limes is very unpredictable. As they become riper, they have less acidity.
- Add sugar to offset acid taste, if desired.
- Vinegar may cause an undesirable flavor.
- Adding acid to over-ripe tomatoes will not increase the acid level enough to ensure a safe product.
Determining Elevation
Water boils at 212°F at sea level. As the elevation increases, water boils at lower temperatures and foods take longer to cook. This map shows Nebraska elevations. You need to know your elevation to determine the correct processing time when canning. For those living outside of Nebraska, you can find your elevation at your local planning commission or zoning office, on a webpage or use an app.

Tomato Juices
Tomato Juice
An average of 23 pounds of tomatoes is needed per canner load of 7 quarts, or an average of 14 pounds per canner load of 9 pints.
- Wash hands with soap and water. Wash, remove stems, and trim off bruised or discolored portions of tomatoes.
- To prevent juice from separating, quickly cut about 1 pound of fruit into quarters and put directly into saucepan. Heat add and crush freshly cut tomato quarters to the boiling mixture. Make sure the mixture boils constantly and vigorously while you add the remaining tomatoes. Simmer five minutes after immediately to boiling while crushing. Continue to slowly add all the pieces. If you are not concerned about juice separation, simply slice or quarter tomatoes into a large saucepan. Crush, heat, and simmer for five minutes before juicing.
- Press both types of heated juice through a sieve or food mill to remove skins and seeds. Add bottled lemon juice or citric acid to jars (see acidification directions). Heat juice to boiling again. Fill jars with hot tomato juice; leave ½-inch headspace. Wipe rims of jars with a dampened clean paper towel. Adjust lids and bands. Process either in a boiling-water canner or steam canner following the processing times in Table 8 or in a pressure canner following the recommended processing instructions in Table 9.
Tomato and Vegetable Juice Blend
An average of 22 pounds of tomatoes is needed per canner load of 7 quarts. Not more than 3 cups of other vegetables may be added for each 22 pounds of tomatoes.
- Wash hands with soap and water. Crush and simmer tomatoes as for making tomato juice. Add no more than 3 cups of any combination of finely chopped celery, onions, carrots, and peppers for 22 pounds of tomatoes. Simmer mixture 20 minutes.
- Press hot cooked tomatoes and vegetables through a sieve or food mill to remove skins and seeds. Add bottled lemon juice or citric acid to jars (see Table 1).
