If you find yourself in a situation where food supplies are scarce, knowing how to preserve food can be a life-saving skill. Proper food preservation techniques can extend the shelf life of perishable items, allowing you to stock up on essentials and have food available for a longer period of time. In this guide, we will explore various methods of survival food preservation, from canning to dehydration, freezing to fermentation, smoking to pickling, and more. By understanding these techniques, you will be better equipped to sustain yourself during challenging times.

Water Bath Canning

Water bath canning is a popular method used for preserving high-acid foods such as fruits, jams, and pickles. The process involves packing the prepared food into glass jars and immersing them in a boiling water bath for a specific period of time. The heat kills any bacteria or microorganisms present, creating a seal that prevents spoilage. Water bath canning is a simple and cost-effective method, making it an ideal choice for beginners or individuals with limited resources.

Pressure Canning

Pressure canning is recommended for low-acid foods such as vegetables, meat, and poultry. Unlike water bath canning, pressure canning requires a pressure canner to reach high temperatures and kill harmful Clostridium botulinum bacteria. This method preserves the nutritional value of the food while maintaining its flavor and texture. Pressure canning may seem intimidating, but with proper guidance and equipment, it is a reliable way to preserve a wide range of perishable items.

Canning Equipment

To successfully can your own food, you will need a few essential tools. These include glass jars with lids and bands, a reliable canning pot or pressure canner, a jar lifter, a canning funnel, and a bubble remover and headspace tool. These tools ensure a safe and effective canning process by facilitating the filling, sealing, and removal of jars from the heat source. Investing in high-quality canning equipment is crucial to achieve optimal results and minimize the risk of spoilage.


Dehydration is a method of food preservation that removes the moisture content from the food, inhibiting the growth of bacteria, yeast, and molds. Dehydrated foods have a long shelf life and retain most of their nutritional value, making them an excellent option for survival situations. There are various methods of dehydration, including using dehydrators, air drying, and sun drying.


Dehydrators are devices specifically designed for removing moisture from food. They use a low heat and airflow system to slowly dry out the food without cooking or damaging it. Dehydrators come in different sizes and with various features, allowing you to effectively dry fruits, vegetables, herbs, jerky, and more. They offer precise temperature control and consistent results, making them a popular choice for home food preservation.

Air Drying

Air drying is a traditional method of dehydration that requires minimal equipment. It involves spreading food in a well-ventilated area, allowing natural air circulation to gradually dry it out. Air drying works well for herbs, flowers, and certain fruits and vegetables that have a low moisture content. However, it may not be suitable for high-moisture foods or in humid climates, as prolonged drying times can increase the risk of spoilage.

Sun Drying

Sun drying is another age-old method of food preservation that harnesses the power of the sun to remove moisture from food. It is a cost-effective technique but highly dependent on favorable weather conditions. Sun drying is commonly used for fruits, vegetables, and meats, and requires careful monitoring to ensure proper drying and prevent contamination. While it may take longer than other methods, sun-dried foods can have an intense flavor and a significantly extended shelf life.


Freezing is a convenient and effective method of preserving food, particularly for short to medium-term storage. It involves lowering the temperature of the food below its freezing point to inhibit bacterial growth and slow down enzyme activity. Freezing can be used for a wide range of perishable items, including fruits, vegetables, meat, fish, and dairy products.

Flash Freezing

Flash freezing is a technique that involves rapidly freezing food at extremely low temperatures. This method preserves the quality of the food by preventing ice crystals from forming and causing cellular damage. Flash freezing is commonly used in commercial food preservation but can also be replicated at home using a deep freezer or dry ice. It is particularly useful when freezing fruits, berries, or delicate items that can easily become mushy or lose their texture.


Blanching is a pre-freezing step that involves briefly immersing vegetables in boiling water or steam and then rapidly cooling them in ice water. Blanching stops enzyme activity and helps retain the color, texture, and nutrients in the vegetables. It also cleanses the surface of any bacteria or dirt. By blanching before freezing, you can ensure that your frozen vegetables maintain their quality and taste.


Proper packaging is essential for successful food freezing. It helps prevent freezer burn, which occurs when food is exposed to air and becomes dehydrated, leading to a loss of flavor and texture. For optimal results, use airtight containers such as freezer bags or vacuum-sealed bags. Make sure to remove as much air as possible before sealing and label each package with the date and contents to keep track of storage times.


Fermentation is a natural process that converts sugars in food into acids, alcohol, or gases using microorganisms such as yeast or bacteria. It is an ancient method of food preservation that not only extends shelf life but also enhances the flavor, texture, and nutritional value of the food. Fermentation is commonly used for vegetables, dairy products, and beverages.

Fermentation Basics

To initiate fermentation, you need a fermentation vessel, such as a jar or crock, and a source of beneficial bacteria or yeast. The food is submerged in a brine or liquid and left at room temperature for a specific period of time. This allows the microorganisms to break down the sugars, creating a tangy taste and preserving the food. Fermentation requires careful monitoring of temperature, hygiene, and time to ensure a safe and successful outcome.

Lactic Acid Fermentation

Lactic acid fermentation is a type of fermentation that occurs when lactic acid bacteria convert sugars into lactic acid. This process is responsible for the tangy flavor and preservation of fermented vegetables such as sauerkraut, kimchi, and pickles. Lactic acid fermentation not only creates a sour taste but also enhances the nutritional value of the food by increasing the bioavailability of certain vitamins and minerals.

Vegetable Fermentation

Vegetable fermentation is a popular way to preserve seasonal produce and enjoy the flavors throughout the year. Common fermented vegetables include cabbage (in the form of sauerkraut or kimchi), cucumbers (as pickles), beets, carrots, and radishes. Fermented vegetables can be added to sandwiches, salads, or consumed as a side dish, providing a healthy and delicious addition to your survival food reserves.


Smoking is a method of food preservation that combines the effects of drying, heat, and exposure to smoke. It not only extends the shelf life of food but also imparts unique smoky flavors. Smoking is commonly used for meats, fish, and cheese, but can also be applied to fruits and vegetables to add a smoky twist to their taste.

Cold Smoking

Cold smoking involves smoking food at temperatures below 85°F (30°C) for an extended period of time. The smoke imparts flavor while the low heat gently dries out the food. Cold smoking is typically done over a longer duration, ranging from hours to days, depending on the desired intensity of the smoke flavor. It is important to note that cold smoking does not cook the food, so additional cooking may be required before consumption.

Hot Smoking

Hot smoking involves smoking food at higher temperatures, usually between 175°F (80°C) and 250°F (121°C), which both cooks and smokes the food simultaneously. It is a faster method of smoking that results in fully cooked and smoked food. Hot smoking is commonly used for salmon, ribs, brisket, and other cuts of meat, creating tender and flavorful dishes that can be enjoyed immediately or stored for future consumption.

Smoking Techniques

There are various smoking techniques you can use to achieve the desired flavors and textures in your smoked food. Some popular techniques include using wood chips or chunks for smoke generation, creating a smoke chamber with the help of a smoker or grill, and using different types of woods for distinct flavors. Experimenting with different smoking techniques and flavors can add a new dimension of taste to your survival food preparations.


Pickling is a preservation method that involves immersing food in a brine or a solution of vinegar and water. This process creates an acidic environment that inhibits the growth of bacteria, effectively preserving the food. Pickling can be done using either a brine or vinegar, depending on the desired flavor and texture of the final product.

Brine Pickling

Brine pickling involves immersing food in a saltwater solution known as brine. The salt in the brine draws out moisture from the food, making it less susceptible to spoilage. Brine pickling is commonly used for cucumbers, olives, and other vegetables. The longer the food is left in the brine, the more it absorbs the flavors of the pickling spices, resulting in tangy and flavorful preserved foods.

Vinegar Pickling

Vinegar pickling, as the name suggests, uses vinegar as the preserving agent. The acidity of the vinegar creates an environment in which bacteria cannot thrive, effectively preserving the food. Vinegar pickling is commonly used for fruits, vegetables, and condiments such as relishes and chutneys. The acidity of the vinegar also imparts a distinctive tangy taste, enhancing the flavor profile of the preserved food.

Pickling Spices

Pickling spices are a key component of pickling, adding aromatic flavors and enhancing the overall taste of the preserved food. Common pickling spices include mustard seeds, dill seeds, coriander seeds, peppercorns, bay leaves, and cloves. Each spice contributes its own unique flavor, allowing you to experiment and create custom pickling blends that suit your preferences.


Salting is an ancient preservation technique that involves using salt to draw out moisture from food, creating an environment unsuitable for bacterial growth. The salt also acts as a natural preservative, extending the shelf life of the food. Salting can be done through various methods such as dry salting, brining, and salt curing.

Dry Salting

Dry salting involves covering the food with a layer of salt to extract moisture and inhibit bacterial growth. It is commonly used for preserving fish, meats, and certain fruits and vegetables. Dry salting requires careful monitoring of temperature and humidity to prevent the growth of harmful bacteria while allowing the food to gradually dehydrate and cure.


Brining is a wet salting method that involves soaking the food in a saltwater solution known as a brine. The saltwater infuses the food with flavor and preserves it by reducing its water content. Brining is often used for poultry and meat, imparting moisture and tenderness to the final product. It is important to use the correct salt-to-water ratio and follow recommended brining times to ensure proper preservation and flavor development.

Salt Curing

Salt curing is a technique that combines dry salting and brining to preserve food for extended periods. It involves rubbing the food with salt and allowing it to sit in a refrigerated or controlled environment. The salt draws out moisture, dehydrating the food and inhibiting the growth of bacteria. Salt curing is commonly used for hams, bacon, and fish, creating flavorful and long-lasting preserved meats.

Root Cellaring

Root cellaring is a method of preserving fresh fruits and vegetables by storing them in a cool, dark, and humid underground space. This traditional technique offers a natural environment that helps maintain the quality and freshness of the produce for an extended period. Root cellaring is particularly effective for storing root vegetables, winter squashes, apples, and other hardy crops.
