Protein is one of the most difficult foods to put up in volume. They are expensive when purchased commercially, don’t last as long as other prepper foods such as grains, and the selection is often limited.
There are several options to rack and stack your protein. First, you can purchase cans of Pork, beef, and chicken. Alternatively, you can add freeze-dried if you are willing to pay the premium. Finally, you can freeze it, and hope the electricity doesn’t go out.
One thing we often fail to consider is Canning up pork ourselves. Pound for pound, pork can be one of the least expensive, and most versatile meats to preserve.
See the note about the “fat cap” below
Pressure canning, as required for pork, is versatile, the final product lasts for years, renders the pork tender, and it compliments so many dishes!
Time to fire up the canner and look at canning pork step by step…

Why Can Pork, Anyway?
So, why put yourself and your pressure canner to work on a few Jars of pork?
First, preserved meats are expensive. Canned chicken online is currently running at about $0.30 per ounce, compared to about $0.12 per ounce for boneless and skinless chicken. Converting to calories, this is your cost for about 50 calories.
Pork, yes, the other white meat, is even more expensive. At $0.41 per ounce canned, putting away enough for a good meal verges on prohibitively expensive.
Again, you’re paying that $0.41 per ounce for about 39 calories. At a sale price of $1.50 per pound for raw pork loin, I can add pork to my freezer at $0.24 per ounce.
Freeze-dried (chicken) is even more costly, at $0.75 per 39 calorie serving. That equates to about $12.50 for 500 calories in a meal.
I usually purchase pork on sale at, or below $1.50 per pound. Specifically, pick up pork loin. The monster hogs they grow these days will yield a +10 pound loin. With little fat, no gristle, a loin is almost pure pantry fare with no waste.

Finally, when you purchase commercially, you have little choice over the flavorings. For example, if you buy canned pulled pork, you better like the sauce.
Canning is a simple way to preserve your protein flavored as you like. Or, as we do, can it plain, and build a dish around it later.
Pressure Canning
Pressure canning is required for low-acid foods. When the pH of a food is less than 4.6, it’s time to put away the water-bath canner and break out the pressure canner.
Pressure canners use a weight or dial gauge to increase the pressure. This results in an increase in the canner’s temperature.
When 212 degrees Fahrenheit (100 Celsius) does not kill pathogens in food, pressure canners raise the temp to about 245 degrees (120 Celsius). This increased temp plus longer canning times suffices to make most other foods safe to preserve.
A lot of the equipment required for pressure canning is the same as that for water-bath. Let’s look at the items you’ll need.
Canning Tools and Equipment
Pressure canners are not water-bath canners. You will need to invest in a quality canner. You don’t need to break the bank, just purchase one from a quality manufacturer.
Pressure canners rely on increased pressure to jack up the internal temp needed to sanitize low-acid foods. The tales of pressure canners exploding are mostly the realm of your grandparents. Modern canners have multiple safety systems that thwart explosive results.

That being said, it’s still possible to get one to pop! Always follow your manufacturer’s instructions. I would also save your pennies and purchase one new, rather than hitting up Good Will or the Salvation Army for a used one. At least until you know what you are looking at.
The first thing you will notice is that your pressure canner is beefier than their thin-metal water-bath cousins. Next, you’ll notice a weight or a gauge (or both). You must become familiar with their operation if you want to avoid food-borne illness.
I’ll leave the specifics of your canner to the user manual. Read it. Then read it again. Then maybe watch a few YouTube videos. Just to make sure you know what you’re doing.
Interestingly enough, several manufacturers also produce electric pressure canners. These are pretty exceptional in a “set it and forget it” kind of way.
The biggest advantage is that they do all the work for you. One disadvantage is that they don’t can everything a regular pressure canner handles. Therefore, read the manual to make sure yours will can meats.
Another advantage of these is that they can small batches. This makes it easy for you to make a little extra soup or stew, pop the extra in the canner, and by morning your pantry is a few quarts deeper!
As for other equipment, I recommend a jar lifter and a lid lifter. Both make the job of handling hot jars and lids easier.
Next on the list are jars, lids, and rings. You will need both. If you are purchasing new, make sure to get canning jars. Decorative jars will not handle the temperatures and pressures if this process.
Note: at the time of this writing, jars are extremely expensive. Shop around and you will find them at normal prices. Better yet, get some hand-me-downs!
Second Note: Lids aren’t re-usable. Once you open the jar, toss them.
Most of my jars are on their 2nd or 3rd generation of use! I routinely, and lovingly, use my grandmother’s canning jars. Not only do they work just fine, but it’s also a great bond and reflection for me. As long as they are free of nicks and cracks, they are good to use.
The last part of the equation is rings. New jars come with rings. You can use these over and over. As long as they are rust-free, they are good.
If you are a novice canner, then be aware there are two different sizes. Regular and wide mouth. I prefer wide-mouth for canning meats, as it’s easier to remove the meat from the jar after canning. Just make sure that your rings, lids, and jars all match.
Pressure Canning Cautions
There aren’t a lot of risks with modern canning. Here are a few of the most common cautions to look out for…
Always read your manual. You may need to adjust weights or pressure based on your elevation. If you live over 1000 feet above sea level, be prepared to make adjustments.
Next are your jars, new or old, check for cracks when you wash them up. Run the edges to see if there are any chips, and check the glass for cracks.
Pay attention to temperature differences! This recipe is a raw-pack variation. You will pack raw and cold pork into your jars. This means you will place them in a canner with cool water.
If you put them in hot or steaming water you risk cracking the jars. The same goes for hot pack recipes. These go into a heated canner.
Ingredients
There are few things easier to can than pork, Specifically, canned pork requires two ingredients: pork and salt. Doesn’t get easier than that.
For pork, I use pork loin. Especially when it’s on sale. To be specific, I mean the whole loin and not the tenderloin. The tenderloin, while good, is too small and expensive to put up in bulk.
A whole pork loin will be between 5 and 10 pounds (between 2.2 and 4.5 kilograms) . When well-trimmed, they have little fat. Even if there is a fat cap, that’s fine. It just adds calories!
Compared to other cuts, like the shoulder or the leg, the loin has no bones. The bones are wasted weight and don’t contribute to your canned goods. You will also spend extra time trimming them out.
Pork loins have between 2 and 3 muscles depending on where they are cut. Most center-cut loins contain only one. This makes butchering quick and easy.
The second ingredient is salt. Canning salt is similar to normal table salt. The primary difference is canning salt does not have anti-caking agents. The anti-caking agents contribute to cloudy canning liquid. It’s not critical, just an aesthetic thing.
Butchering Pork For Canning
Cutting up a pork loin couldn’t be easier. The only rule is the pieces should not be thicker than ¾”. Thicker than ¾” and the times and temperature will be insufficient to reach the center of the cubes. This makes for unsafe canning and the potential for illness.
When processing a loin, first slab it out. I cut the entire loin into ¾ inch rounds. Each slice then gets cut into ¾” cubes. That’s it for butchering
You can plan on approximately 2 pounds of pork per quart. If you choose to can in pint jars, then each one will hold approximately 1 pound of pork.
Raw Canning
There are two primary meat canning methods: raw pack and hot pack.
Raw pack is exactly like it sounds. You cut the raw pork into cubes and pack it into the jars, then pop the sealed jars into the canner.
Hot pack requires you to cut and cook the pork before canning. Hot pack has two advantages…
First, you can flavor the meat before canning. Many hot pack recipes require you to boil the meat in plain or flavored liquid. More flavor, more fun!
Second, while cooking, the meat shrinks, so you can fit more in a jar. You will top it off with the cooking liquid but you will get more finished product per jar. The disadvantage here is that hot pack canning takes more time and effort.
If you prefer the easy path, I recommend raw packing. Raw pack shrinks while it cooks and makes its own juice. I especially love raw packed chicken! The resulting juice is the best stock you’ll ever have.
Safety
There are two major safety considerations. The first is the longevity of your canned pork. The USDA states that commercially canned goods are OK to eat as long as the can has no rust, isn’t bulging, and the seal is intact. Home-canned goods, on the other hand, shouldn’t be eaten after 1 year.
That being said, I may have a few jars that have been on the shelf longer than a year. For any jar that is over one year old, I follow the canning safety rules.
First, I look at the color of the liquid in the jar. Is it clear? Is it a “normal” color? If either answer is false, then I dump the jar.
Second, I check the lid. Is it dimpled? Is it tight to the jar? Is there a “hiss” when I open it? Again, if anything is false, then the contents get dumped.
Third, I open the jar and smell and look. Does it smell right? Does it look right? If not, then toss.
Spoilage is nothing to mess with. Trust your senses, trust your gut. If you have any doubt, dump the contents and wash the jar.
I have probably canned hundreds of jars. Out of all those, I’ve lost less than 10. And the ones that contained meat were obviously bad. If the mold growth didn’t scare us away, the smell would have. The bad cans were found during our annual review and re-organization.
Time to start canning!
