Canning Tomatoes and Tomato Products

Quick Tips...

Tomato Acidity

Although tomatoes are considered a high-acid food (pH below 4.6), certain conditions and varieties can produce tomatoes and tomato products with pH values above 4.6. When this happens, the product must be canned in a pressure canner as a low-acid product or acidified to a pH of 4.6 or lower with lemon juice or citric acid.

 

Research has found several conditions that can reduce the acidity of tomatoes. These include decay or damage caused by bruises, cracks, blossom end rot or Insects, and over-ripening. Tomatoes grown in the shade, ripened in shorter hours of daylight, or ripened off the vine tend to be lower in acidity than those ripened in direct sunlight on the vine. Also, tomatoes attached to dead vines at harvest are considerably less acidic than tomatoes harvested from healthy vines. Decayed and damaged tomatoes and those harvested from frost-killed or dead vines should not be home canned.

 

To ensure safe acidity in whole, crushed or juiced tomatoes, add lemon juice or citric acid when processing in a boiling water bath. Add 2 tablespoons of bottled lemon juice or 1/2 teaspoon of citric acid per quart of tomatoes. For pints, use 1 tablespoon bottled lemon juice or 1/4 teaspoon citric acid. Acid can be added directly to the jars before filling with product. Add sugar to offset the taste, if desired. Four tablespoons of a 5 percent acidity vinegar per quart can be used instead of lemon juice or citric acid. However, vinegar may cause undesirable flavor changes.


Process Carefully to Avoid Spoilage

The most common reasons for spoilage in home-canned tomato products are under processing and incomplete seals. Tomatoes that have not been processed long enough to destroy molds and heat-resistant bacteria may spoil during storage. One of the common spoilage organisms, Bacillus coagulans, is very heat resistant and causes flat-sour spoilage. The jar lid may still be sealed and the product may appear normal, but the tomatoes will smell sour because of lactic acid produced by the growth of B. coagulans in the product. Never use tomatoes or tomato juices with off-odors.

Molds can grow on the surface of improperly processed tomato products and may eventually reduce the acidity to a point where botulism-producing spores can grow and produce a deadly toxin. Because even minute amounts of botulism toxin can cause fatal illness, discard without tasting any canned products that show mold growth on the surface. Discard them where they cannot be eaten by other people or animals.

The processing times in this fact sheet are designed to ensure sufficient destruction of bacteria and molds. Where appropriate, processing recommendations for both water bath and pressure canning are given. In general, a pressure canner results in higher quality and more nutritious canned tomato products.

Yield Information

One bushel of fresh tomatoes weighs 53 pounds and yields approximately 18 quarts of canned tomatoes or 15 to 18 quarts of juice. Approximately 2 1/2 to 3 1/2 pounds of fresh tomatoes makes 1 quart of canned tomatoes.

Prepare Jars and Equipment

Standard mason jars are recommended for home canning. Be sure all jars and closures are perfect. Discard any with cracks, chips, dents or rust. Defects prevent airtight seals.

Wash jars in hot, soapy water and rinse well before using. Prepare metal lids as manufacturer directs.

Prepare Tomatoes

Select fresh, firm, ripe tomatoes. Do not can soft, overripe, moldy or decayed tomatoes or tomatoes harvested from dead or frost-killed vines. Green tomatoes are more acidic than ripened tomatoes and can be canned safely with any of the following recommendations.

 

Wash tomatoes well and drain. Dip in boiling water for 30 to 60 seconds or until the skins split. Then dip in cold water. Use a sharp knife to cut out the stem and all of the white core beneath the stem. Peel off the skin. Trim off any bruised or discolored portions.

Close Jars and Process

After jars are filled with food, remove trapped air bubbles, adjust the headspace, and clean the jar tops before processing. To remove trapped air bubbles, insert a nonmetallic spatula or knife between the food and the jar. Slowly turn the jar and move the spatula up and down to allow air bubbles to escape. Add more liquid if necessary to obtain the proper headspace (see recipes in Table 1). Wipe the jar rim with a clean, damp paper towel to remove any food particles. Place pretreated lid on the jar. Turn the screw band fingertip tight.

 

The jars are now ready to process in a boiling water bath or pressure canner.

After processing, carefully remove jars from canner and place on rack, dry towel or newspaper. Allow jars to cool untouched, away from drafts, for 12 to 24 hours before testing seals. To test jar seals, press flat metal lids at the center of lid. It should be slightly concave and not move. Remove screw bands. Label sealed jars with contents, canning method and date. Store in a clean, cool, dry, dark place.

Reprocessing

Jars of tomatoes or tomato products that do not seal can be safely reprocessed within 24 hours of the initial processing. However, if the jar sealed at first and then unsealed a few days later, spoilage is indicated. Do not reprocess such jars; destroy the contents.

To reprocess, remove lids and empty the food and liquid into a pan. Heat to boiling and pack into clean, hot jars. Put on new pretreated lids. Process again for the full time.

The quality of twice-processed foods may be lower, with textural changes and additional loss of heat-sensitive nutrients such as vitamin C and B-complex.

 

General

 

Quality: Select only disease-free, preferably vine-ripened, firm fruit for canning.

 

Caution: Do not can tomatoes from dead or frost-killed vines. Green tomatoes are more acidic than ripened fruit and can be canned safely with any of the following recommendations.

 

Acidification: To ensure safe acidity in whole, crushed, or juiced tomatoes, add 2 tablespoons of bottled lemon juice or 1/2 teaspoon of citric acid per quart of tomatoes. For pints, use 1 tablespoon bottled lemon juice or 1/4 teaspoon citric acid. Acid can be added directly to the jars before filling with product. Add sugar to offset acid taste, if desired. Four tablespoons of a 5 percent acidity vinegar per quart may be used instead of lemon juice or citric acid.  However, vinegar may cause undesirable flavor changes.  When a procedure for canning tomatoes offers both boiling water and pressure canning options, all steps in the preparation (“Procedure”) are still required even if the pressure processing option is chosen. This includes acidification. The boiling water and pressure alternatives are equal processes with different time/temperature combinations calculated for these products.

 

Recommendation: Use of a pressure canner will result in higher quality and more nutritious canned tomato products. If your pressure canner cannot be operated above 15 PSI, select a process time at a lower pressure.

 

TOMATO JUICE

 

Quantity: An average of 23 pounds is needed per canner load of 7 quarts, or an average of 14 pounds per canner load of 9 pints. A bushel weighs 53 pounds and yields 15 to 18 quarts of juice—an average of 3-1/4 pounds per quart.

 

Procedure: Wash, remove stems, and trim off bruised or discolored portions. To prevent juice from separating, quickly cut about 1 pound of fruit into quarters and put directly into saucepan. Heat immediately to boiling while crushing. Continue to slowly 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 5 minutes after you add all pieces.

 

If you are not concerned about juice separation, simply slice or quarter tomatoes into a large saucepan. Crush, heat, and simmer for 5 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 instructions on page 3-5. Heat juice again to boiling. Add 1 teaspoon of salt per quart to the jars, if desired. Fill hot jars with hot tomato juice, leaving 1/2-inch headspace. Wipe rims of jars with a dampened clean paper towel. Adjust lids and process. (Acidification is still required for the pressure canning options.)

Recommended process time in a boiling-water canner at altitudes of 3,001 - 6,000 feet is 45 minutes for pints and 50 minutes for quarts.

Recommended process time in a dial-gauge pressure canner at altitudes of 4,001 - 6,000 feet is 15 minutes for pints and quarts at 13 lb. pressure.

Recommended process time in a weighted-gauge pressure canner at altitudes above 1,001 feet is 15 minutes for pints and quarts at 15 lb. pressure.

TOMATO AND VEGETABLE JUICE BLEND

Quantity: An average of 22 pounds of tomatoes is needed per canner load of 7 quarts. No more than 3 cups of other vegetables may be added for each 22 pounds of tomatoes.

Procedure: Crush and simmer tomatoes as for making tomato juice (see page 3-5). Add no more than 3 cups of any combination of finely chopped celery, onions, carrots, and peppers for each 22 lbs 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 acidification directions on page 3-5. Add 1 teaspoon of salt per quart to the jars, if desired. Reheat tomato-vegetable juice blend to boiling and fill immediately into hot jars, leaving 1/2-inch headspace. Wipe rims of jars with a dampened clean paper towel.  Adjust lids and process. (Acidification is still required for the pressure canning options; follow all steps in the Procedures above for any of the processing options.)

TOMATOES-CRUSHED (with no added liquid)

A high-quality product, ideally suited for use in soups, stews, and casseroles. 

 

Quantity: An average of 22 pounds is needed per canner load of 7 quarts; an average of 14 fresh pounds is needed per canner load of 9 pints. A bushel weighs 53 pounds and yields 17 to 20 quarts of crushed tomatoes—an average of 2-3/4 pounds per quart.

 

Procedure: Wash tomatoes and dip in boiling water for 30 to 60 seconds or until skins split. Then dip in cold water, slip off skins, and remove cores. Trim off any bruised or discolored portions and quarter. Heat one-sixth of the quarters quickly in a large pot, crushing them with a wooden mallet or spoon as they are added to the pot. This will exude juice. Continue heating the tomatoes, stirring to prevent burning. Once the tomatoes are boiling, gradually add remaining quartered tomatoes, stirring constantly. These remaining tomatoes do not need to be crushed. They will soften with heating and stirring. Continue until all tomatoes are added. Then boil gently 5 minutes. Add bottled lemon juice or citric acid to jars.   Add 1 teaspoon of salt per quart to the jars, if desired. Fill hot jars immediately with hot tomatoes, leaving 1/2-inch headspace. Remove air bubbles and adjust headspace if needed. Wipe rims of jars with a dampened clean paper towel. Adjust lids and process.

STANDARD TOMATO SAUCE

Quantity: For thin sauce—an average of 35 pounds is needed per canner load of 7 quarts; an average of 21 pounds is needed per canner load of 9 pints. A bushel weighs 53 pounds and yields 10 to 12 quarts of sauce—an average of 5 pounds per quart. For thick sauce—an average of 46 pounds is needed per canner load of 7 quarts; an average of 28 pounds is needed per canner load of 9 pints. A bushel weighs 53 pounds and yields 7 to 9 quarts of thick sauce—an average of 6-1/2 pounds per quart.

Procedure: Prepare and press as for making tomato juice, see page 3-5. Simmer in large diameter saucepan until sauce reaches desired consistency. Boil until volume is reduced by about one-third for thin sauce, or by one-half for thick sauce. Add bottled lemon juice or citric acid to jars. See acidification directions on page 3-5. Add 1 teaspoon of salt per quart to the jars, if desired. Fill hot jars, leaving 1/4-inch headspace. Remove air bubbles and adjust headspace if needed. Wipe rims of jars with a dampened clean paper towel. Adjust lids and process. (Acidification is still required for the pressure canning options.)

SALSAS

These salsas recipes, as well as most salsas, are mixtures of low-acid foods, such as onions and peppers, with acid foods, such as tomatoes. It is important that ingredients be carefully measured and that the salsas be made as described to be processed safely in a boiling water canner.

SELECTION AND PREPARATION OF INGREDIENTS

ACIDS

The acid ingredients help preserve canned salsas. You must add the acid to these salsas processed in a boiling water canner because the natural acidity of the mixture without it may not be high enough. The acids are usually commercially bottled lemon juice or vinegar so the acidity level will be standardized. Use only vinegar that is at least 5% acidity; do not use homemade vinegar or fresh squeezed lemon juice because the acidity can vary and will be unknown.

The amounts of vinegar or lemon juice in these recipes cannot be reduced for safe boiling water canning. Sugar can be used to offset the tartness of the acid. An equal amount of bottled lemon juice may be substituted for vinegar in recipes, but do not substitute vinegar for lemon juice. This substitution will result in a less acid and potentially unsafe canned salsa.

TOMATOES

The type of tomato will affect the consistency of salsa. Paste tomatoes, such as Roma, have more, and usually firmer, flesh than slicing tomatoes. They will produce thicker salsas than large slicing tomatoes which usually yield a thinner, more watery salsa.

Canning is not a way to use overripe or spoiling tomatoes. Use only high quality, disease free, preferably vine-ripened, firm tomatoes for canning salsa or any other tomato product.

Do not use tomatoes from dead or frost-killed vines. Poor quality or overripe tomatoes will yield a thin salsa and one that may spoil. Green tomatoes or tomatillos may be used for ripe tomatoes in these recipes, but the flavor of the recipe will change.

When recipes call for peeled tomatoes, remove the skin by dipping washed tomatoes into boiling water for 30 to 60 seconds or until skins split. Dip immediately into cold water, then slip skins off and core the tomato.

TOMATILLOS

Tomatillos are also known as Mexican husk tomatoes. The dry outer husk must be removed, but they do not need to be peeled or have the seeds removed. They will need to be washed well after the husk is removed.

PEPPERS

Peppers range from mild to scorching in taste. It is this “heat” factor that makes many salsa fans want to experiment with recipes. Use only high quality peppers, unblemished and free of decay. You may substitute one type of pepper for another, including bell peppers (mild) for some or all of the chiles. Canned chiles may be used in place of fresh. However, do not increase the total amount (pounds or cups) of peppers in any recipe. Do not substitute the same number of whole peppers of a large size for the number of peppers of a smaller size (for example, do not use 6 bell peppers or long chiles in place of 6 jalapeños or serranos). This will result in changing the final acidity of the mixture and potentially unsafe canned salsa.

Milder varieties of peppers include Anaheim, Ancho, College, Colorado and Hungarian Yellow Wax. When the recipe calls for “long green chiles” choose a mild pepper. Jalapeño is a very popular hot pepper. Other hot varieties include Cayenne, Habanero, Serrano and Tabasco.

Do not touch your face, particularly the area around your eyes, when you are handling or cutting hot chiles. Caution: Wear plastic or rubber gloves and do not touch your face while handling or cutting hot peppers. If you do not wear gloves, wash hands thoroughly with soap and water before touching your face or eyes.

Usually when peppers are finely chopped in a salsa, they do not need to be peeled. However, many recipes say to peel the recipes, and the skin of long green chiles in particular may be tough after canning. If you choose to peel chiles, or procedures with a recipe direct you to peel the peppers, use the following.

Peeling peppers: Wash and dry peppers; slit each pepper along the side to allow steam to escape. Blister skins using one of these two methods :

Oven or broiler method to blister skins – Place peppers in a hot oven (400°F) or under a broiler for 6 to 8 minutes until skins blister.  

Range-top method to blister skins – Cover hot burner (either gas or electric) with heavy wire mesh.  Place peppers on burner for several minutes until skins blister. 

 To peel, after blistering skins, place peppers in a pan and cover with a damp cloth. (This will make peeling the peppers easier.) Cool several minutes; peel off skins. Discard seeds and chop.

SPICES AND HERBS

Spices and herbs add unique flavoring to salsas. The amounts of dried spices and herbs in the following recipes (black pepper, salt, dried oregano leaves, and ground cumin) may be altered or left out. For a stronger cilantro flavor in recipes that list cilantro, it is best to add fresh cilantro just before serving instead of adding more before canning.

OTHER

Red, yellow or white onions may be substituted for each other. Do not increase the total amount of onions in any recipe.

IMPORTANT: You may change the amount of spices, if desired. Do not can salsas that do not follow these or other research tested recipes. (They may be frozen or stored in the refrigerator.)

RECIPES

IMPORTANT: Follow the directions carefully for each recipe. Use the amounts of each vegetable (peppers, onions, tomatoes, tomatillos, etc.) listed in the recipe. If the  procedures call for chopped tomatoes, use the whole tomato after peeling and coring. Do not drain the tomato, or remove all the liquid and juices. Add the amount of vinegar or lemon juice as listed. The only changes you can safely make in these salsa recipes are to substitute bottled lemon juice for vinegar and to change the amount of dried spices and herbs. Do not alter the proportions of vegetables to acid and tomatoes because it might make the salsa unsafe. Do not thicken salsas with flour, cornstarch or other starches before canning. If a thicker salsa is desired, you can pour off some of the liquid or add these thickening ingredients after opening.
