Home Canning Tuna

The high levels of omega-3 fatty acids in tuna fish may help to reduce the level of omega-6 fatty acids and LDL cholesterol that can accumulate inside the arteries of the heart. Studies have shown that eating more omega-3 is associated with reduced rates of cardiovascular disease, including heart attacks.

Healthline shares some information on the health benefits of canned tuna; however, the beauty we have as home canners is we are able to control the level of sodium per jar whereas commercial canners go overboard adding salt. So you if you are on a low-sodium diet, home canning tuna is the best way to enjoy this protein and omega packed seafood.

Instructions for Pressure Canning Tuna

Tuna may be precooked and hot packed or left raw and raw packed. Whether raw or hot packing, tuna must be skinned.

1. If raw packing, it is easiest to cut tuna when it is partially frozen. Remove the skin with a sharp knife and scrape the surface lightly to remove blood vessels and discolored flesh. Then proceed to Step 3.
2. If hot packing, remove the viscera and wash in cold water. Drain all the blood from the tuna and remove the skin with a sharp knife. Place the cleaned tuna, belly-down on a baking sheet and bake at 350 degrees Fahrenheit for 1 hour or to an internal temperature of 165 degrees Fahrenheit. Refrigerate the tuna overnight to firm so you may home can the next day.
3. Separate the tuna into quarters by cutting the meat away from the bones. Pull off and cut out all bones and the fin base, then scrape and cut out all the very dark flesh as it has a very strong flavor and will make the other meat distasteful. Unless you like such a strong flavor – then keep it!
4. Cut the quartered tuna crosswise into 2- to 4-inch lengths, depending on whether you are packing into wide-mouth pint and half-pint jars. Pack the tuna tightly into the jars, leaving 1-inch headspace. If you wish to add salt, add 1 teaspoon of salt for each pint and 1/2 teaspoon into each half-pint.
5. Do not cover the tun with water. If you chose to precook the tuna, add 1 tablespoon vegetable oil to each pint jar and a 1/2 teaspoon to each half-pint jar, and maintain 1-inch headspace.
6. Wipe the rim of each jar with a warm, wet washcloth dipped in vinegar. Place the lid and ring on each jar and hand tighten.
7. Add cool water in your pressure canner per the manufacturer requirements, often 3 quarts. Place cool jars in the pressure canner, lock the pressure canner lid, and place canner on high medium-high heat  for 15 minutes. Increase heat to high after 15 minutes to allow the canner to get hot enough to vent.
8. Let the canner vent for 10 minutes. Close the vent and continue heating to achieve 11 PSI for a dial gauge and 10 PSI for a weighted gauge, or according to your elevation. Process both pints and half-pints for 100 minutes (1 hour and 40 minutes).
9. When timer goes off and processing is done, turn off heat and allow the pressure in the canner to naturally get back to zero. This could take upwards of 45 minutes or more. Once canner is at zero PSI, remove canner lid, being sure deflect the steam from your face. Allow canner to sit for 10 minutes undisturbed prior to removing jars from the canner.
10. Place jars on a cutting board and allow to cool undisturbed for a minimum of 8 hours or overnight. Once all the lids have sealed, and jars have fully cooled, remove the rings and wash jars in warm soapy water. Store rings to reuse, then label each jar with name and date then store.
