15 Old-School Ways to Preserve Food

While food is not the top priority in survival situations, it is still one of the four pillars of survival.  If you go long enough without food, your body starts to eat itself. It starts by breaking down fat.

Then it tears down muscle mass. Finally, it starts to feed on internal organs and the brain itself. Early in this process you will feel weak, disoriented, and depressed.  Eventually it ends in death.

The dilemma in a SHTF scenario is how to have food supplies that will last, and how to preserve the food you acquire. All food is susceptible to mold, bacteria, and insects if exposed to moisture and warm temperatures.  Therefore, measures must be taken to keep food in a state that allows it to last as long as possible.

Food preservation these days is simple. Our dry food sits on a shelf, while fruits, veggies, and dairy are in the refrigerator. Meat is stacked in a deep freeze so we can thaw it out whenever we are ready.  We have three freezers full of meat.

However, these methods become difficult if we have no electricity or if that electricity is limited. There are primitive food preservation methods that have been used for thousands of years.  In this article we will cover ways to preserve your food without electricity.

Dehydration

If you’re just beginning to learn about food preservation, one of the simplest methods to preserve food without electricity is dehydration. You can of course use an electric dehydrator if you have power available, but it’s also simple to dehydrate without any electricity at all.

All you need is a couple of screens, some sunshine, and a nice breeze. It’s a good idea to learn to dehydrate food because the result is lightweight, portable, and takes up a lot less storage space. You can learn more about how to dehydrate food without electricity in the video below:

Dehydrated meats, herbs, fruits, or vegetables, once done, should be kept in a cool dry area away from direct sunlight until you are ready to eat.

You can dehydrate foods by smoking, sun-drying, and using an electric dehydrator.  For this article we will skip the dehydrator and focus on methods that require no electricity. Sun-drying food is the easiest method by which you can dehydrate.

For this process you will need to cut your food as thin as possible.  It needs to be ¼ inch thick or less.  Scoring both sides of the food will further help with the dehydration process.  You can either build a rack on which you can place your food, or you can string up your strips of food with cordage.

Ideally, you want to put your food in a spot that has direct sunlight but is also breezy.  This will keep the flies away. It should be high enough that animals cannot reach it.  Generally, it will take several days to sun dry foods.

You will know it is done when it has the consistency of jerky.  When you squeeze the food, no moisture should come out.  You can speed up the process by adding salt and spices.

Fermentation

The process of fermentation is one that is not discussed much but is used by most civilizations.  It is accomplished by combining yeast and sugars in a way that preserves the liquid and produces alcohol.

Whether used for trading or for yourself, knowing how to complete this process is valuable.  The three types of fermentation are Ethyl alcohol, Lactic acid, and Acetic acid fermentation. You can ferment a wide variety of foods including fruits, vegetables, sugar, beer, wine, or milk.

The process of fermentation is complex and requires knowledge of how oxygen levels, temperature, and timing alter results. Sauerkraut, pickles, kimchi, sourdough bread, apple cider vinegar, yogurt, wine, apple cider, and beer are all made through fermentation.

The products produced can range from medicinal wines to products used to kill bacteria in water or wounds.:There are also a lot of health benefits that come with fermenting your food. The basics of fermentation are in the video below:

Vinegar Pickling

Everyone knows you can pickle cucumbers and you’ve probably heard of pickled eggs. But did you know that you can pickle just about anything? Pickling your vegetables, such as okra, tomatoes, or carrots can extend their shelf life up to three times longer than usual.

You can even pickle fruits such as peaches, grapes, and watermelon rinds. If you choose to boil the vinegar first, it can help to meld all the different flavors together but let it cool before adding your vegetables, so you don’t partially cook them and lose that wonderful crunch.

Olive Oil Preservation

Used for centuries in countries of the Mediterranean region and notably Italy (called sott’olio), Spain (en aceite de oliva), and France (l’huile), preserving food with olive oil can help you bolster your long-term food stockpile.

Olive oil is best used to preserve foods that might normally be cooked in olive oil, such as meats, fish, certain vegetables, herbs, and cheese. Foods preserved in olive oil can be stored at room temperature for a year or more, in a refrigerator for several weeks, or the freezer for up to 12 months.

Decide how long you want to store your food so you can process it safely. To store foods in olive oil at room temperature, they must be prepared using a boiling vinegar or salted water solution first.

Tips for Preserving Food in Olive Oil

  • Thoroughly dry vegetables after washing them
  • Use vegetables free of rot or blemishes if packing in oil
  • Since vinegar can react with some metal pans, use stainless steel cookware for best results when cooking foods to store in olive oil.
  • Glass containers are best. Caps should close tightly. Use extra virgin olive oil to completely submerge food.
  • As with home canning, use your nose and best judgement prior to eating food stored in olive oil. Do not eat food from containers that are obviously leaking or that have bulging caps.

Mineral Oil Preservation

One of things that many preppers are excited to find out they can preserve are eggs. Most Americans store eggs in their refrigerator to keep them from going bad. But the thing to understand with this is that store bought eggs arrive at the store having already been washed and refrigerated.

The natural bloom that would preserve those eggs was washed off during the packaging process. So, store bought eggs must be refrigerated or they will not last too long.

But if you are prepper who is raising your own chickens or if you have access to freshly laid chicken eggs, you probably already know that freshly laid unwashed eggs will keep just fine on your kitchen counter, out of direct sunlight, for several weeks.

But did you also know that you can use mineral oil to preserve those eggs for 9 months to a year!?The first key to preserving eggs using mineral oil is not to wash the freshly laid eggs until you are ready to eat them.

Washing will remove the protective bloom on the eggs and will allow bacteria to get inside the shell. Instead, lightly brush off any clumps of dirt or rub lightly with a towel.

Then coat the eggs with a thick layer of mineral oil. Be sure you have completely coated the entire shell. Place the egg in an egg carton. Store the eggs away from direct sunlight, on your counter.

Once a week for the first month, flip each egg over in the carton. After the first month you don’t have to turn the eggs anymore. You can move the eggs to a cool, dry place to store them until you need them.

When you are ready to use the eggs, fill a bowl with cold water and put the eggs into it. The eggs that float to the top of the water have gone bad. The ones that sink are good to eat. If you have any doubt, throw it out. Take the eggs that are still good and wash them off before using or before boiling for use.

Root Cellar or Cold Storage

For anyone over 50 years old or so, you’ve probably seen a root cellar or cold storage area used, most likely by your grandparents. A root cellar or cold storage area is a cool, dark, damp area used to store and preserve root crops like apples, potatoes, cabbage, beets, carrots, etc.

If you have an old home, you may have a section of basement that was turned into a cold storage area. A cold storage area is typically lined with narrow wooden shelves which typically included a lip at the front to keep glass jars from falling off and breaking during an earthquake or storm.

Ventilation is critical for root cellar or cold storage of produce so make sure you store fruits and vegetables in mesh bags, burlap bags, laundry baskets, or boxes and tray with large holes.

Before storing garlic, onions, potatoes, and sweet potatoes, cure them for 2 to 4 weeks by laying them out to dry (not in direct sun) at temperatures between 55-80 degrees, depending on the vegetable.

The outside skin will harden which helps them to last longer in cold storage. In primitive situations, root cellar storage can even be a trench or hole in the ground, or even a cavity beneath the roots of a tree.

Waxing and Beeswax Wraps

One of the less commonly known ways of preserving food, especially fruits and vegetables is using beeswax wraps or other forms of wax. Beeswax wraps are an all-natural way of preventing loss of moisture and protecting food during long-term storage.

Beeswax can prevent shriveling and spoilage in cheeses, fruits, and vegetables. The wraps are similar to plastic wrap and cling firmly to your food to help delay browning, retain moisture, and prevent spoilage. You can buy beeswax wraps or make your own as shown in the video below:

Other types of wax that can be used for preservation of foods include paraffin, carnuba wax, shellac, and candelia wax.

You’ll find wax coating used for preservation most often on citrus fruits such as oranges, lemons, and limes as well fruits like melons, cantaloupes, apples, pineapple, passion fruit, peaches, and apples.

Wax is also used for preserving avocados, bell peppers, turnips, squash, pumpkins, eggplant, sweet potatoes, and cucumbers. To remove a wax coating simply scrub your fruits or vegetables lightly before eating.

You may have even seen your mom or grandmother use paraffin wax as an additional seal on jam jars when canning. You can also preserve cheeses using wax as seen in the video below:

Freezing

The practice of freezing food can be much more difficult without electricity. When it comes to meat and fish, freezing is by far the best way to preserve your proteins.

To keep the food fresh, you will need temperatures at 30F or below. To do this you will likely need to pile snow or ice to create a chamber for storing your food. This would only work during winter months in most parts of the world.

If you are worried about animals and you happen to have weather that keeps the air temperature below 30F, you can hang your food in a bear bag.  This would need to be at least 10 feet off the ground.

Freeze Drying

To take your long-term food storage to the next level, consider learning to freeze your dry food now while electricity is available. Just about any type of food can be freeze dried including vegetables, fruits, meats, and even desserts or entire meals.

When properly prepared and stored, freeze dried food can last up to 25 years! To top it off, food that has been freeze dried can be reconstituted and still have all its nutritional value and taste. That means if you freeze dry food now, you can store it away and not have to think about it for at least a quarter century unless you need to.

If your budget can afford it and while you still have power available, you can freeze dry foods using a machine as shown below:

Canning

When I was a child, I spent my summers at my grandparents’ house in the Ozark Mountains. They had an enormous garden that was easily larger than their house. Most of the fruits and vegetables that were yielded ended up in jars lining the walls of their garage.  Canning ensured that they would always have a food supply even if the garden had an off year.

Fruits, vegetables, meats, and fish can all be canned if it is done properly.  I started my canning career by making sweet pickles and then expanded from there. We have canned everything from tomatoes to peaches to bacon to venison.

For any type of canning (water bath, pressure canning), you will need mason jars of appropriate size, lids, rings, and jar tongs to remove the jars from hot water. Fruits and vegetables can be canned using a large pot with boiling water.

Meats typically require a pressure canner to get a good finished product.  It should also be noted that dents in the lids or rings can be an issue along with any nicks along the lip of the jar.  If a good seal is not created, the food will not be safe to eat.

Canning is an art form that can take years and years to perfect.  By adding sugar, salt, herbs, and spices you can manipulate the flavor of the finished product in several ways.

For basic canning of vegetables, you will need to wash the jars, lids, and rings thoroughly. You will then need to heat all those elements in a large pot with boiling water. While still hot, add your prepared vegetables and liquids to the jar.

Apply your lid and ring and submerge the jars in boiling water with at least one inch of water above the lid. After 10 minutes, use the tongs to remove the jars and set them on a towel.

Let them sit and cool for a while and then check to make sure the lid is sucked in versus bulging out.  If the jar and lid do not have a good seal, you will need to try and re-submerge the jar to create a better seal.

The video below is a very good overview of the basics of home canning:

Cooling

While cooling your foods does not preserve them nearly as well as freezing them, there is always a need to keep them cool to preserve them for shorter periods of time.

Without electricity, your refrigerator is out of the question.  Cooling is easy during the winter, but how do you keep your foods cool in the summer months?  Try a zeer pot, also known as an evaporation cooler. For years I looked for a way to keep food cool in the summer without electricity, and then I found this method.

This design works with the same principle as an electric refrigerator. For this project you will need two large clay pots with one slightly larger than the other. Put a layer of sand in the bottom of the larger pot and set the smaller pot on top.  Then fill in the gap between the two pots with sand.

Douse the sand with water and place your food inside the smaller pot.  Cover with a white towel and place the whole device in a breezy, sunny area.

The evaporating water will cool the contents by about 30F, which should keep it in the safe range to preserve your food for a while.  You will need to keep adding water to the sand to keep it moist.

The video below provides a visual of a basic zeer pot refrigerator. The larger your clay pots, the more storage space you will have available in your zeer pot fridge:

Drying/Smoking

By far my favorite method by which to preserve food is dehydration.  By removing moisture from foods, you eliminate the potential for mold and bacteria to grow.  It also leaves your food in a form that is lightweight and takes up little space.

Not all foods will dehydrate well, so you may have to blanch, boil, or pickle the foods before you dry or smoke them.  

Smoking is my favorite method for preserving food.  This process dries out the food and adds a pleasant smoky flavor. The smoke also helps eliminate bacteria, and the heat dries out the food faster.

To smoke your food, you will still want to cut it into strips that are less than ¼ inch thick.  Build a fire and let it burn down to coals. Build a tripod above the coals and either build racks or use cordage to suspend the food. You want the heat to be mild enough to avoid cooking it.

You should be able to hold your hand above the coals at the height of the food for eight seconds before having to move it. It typically takes eight to ten hours to smoke most foods.

You can add salt and spices to speed up the process. If you want to hold in the smoke better, you can wrap a blanket or tarp around the tripod. Just be careful that it does not melt or catch on fire.

The video below shows you how to build your own backyard smokehouse from scratch:

Curing

Curing meat is the process of using salt and sodium nitrate to draw moisture out of meat. A mixture of salt, curing salt, and spices are rubbed all over the meat and then it is cooled for a week.

Then the meat is rinsed, wrapped in cheesecloth, and hung for anywhere from a few weeks to several years to dry and age the meat.

Salting

Salting is the process of completely encasing meat in a thick layer of salt for several days.  The salt draws the moisture out of the meat creating a hard shell of salt. After the meat is done drying, the shell is broken, and the meat rinsed and dried.

Additional Resources for Curing including Salting, Drying, and Smoking Meats:

Preserving Meat in Lard

One final way that you can preserve food is with lard. This is an older practice and was primarily used to preserve salt cured meat such as pork and beef. You’ll need a small crock with a jar lid and a seal as well as a sheet of wax paper.

Use salt cured meat or cook the meat as you would if you were going to serve it. Then place the cooled meat into the crock and pour hot pork fat over it. Use enough lard to completely cover the meat so the level is a few inches over the top of the meat.

Place the wax paper on the top of the lard and seal the crock with the jar lid and seal. Place the crock in a cool place and the meat will store up to six months.

You can remove pieces of meat from the crock as you need it. After you remove the meat you need, push the lard back down completely over the remaining meat to keep air from getting to it. Never try to preserve meat with lard in a climate or area which gets extremely hot.

In Conclusion

As you can see, there are plenty of primitive methods for preserving foods without electricity. The key to using these processes is having some practice before you need to rely upon them.

Take the time to try out these techniques now, and start to build your preserved food supply.  With a little effort and experience, you will stay fed when SHTF.
