The following sections will guide you to understand the basic principles of nature conservation , then explore each technique in depth, with specific examples and practical advice.

2. The main principles of natural conservation

Before delving into specific techniques, it is crucial to understand the fundamental principles of food preservation without refrigeration . These rules serve as the basis for all methods: fermentation, drying, salting, slow cooking, or cellar storage.

2.1 Controlling the temperature

Temperature is the most crucial factor in slowing the growth of bacteria and mold:

• Cool (10-15°C) : ideal for root vegetables (carrots, potatoes, beets), apples and pears. A cellar or cool cupboard is perfect.
• Room temperature (18-22°C) : suitable for lactic fermentations (sauerkraut, kimchi) and some non-sterilized preserves.
• Avoid heat (>25°C) : accelerates the development of microorganisms and reduces shelf life.

Tip: a kitchen thermometer placed in your pantry or cellar will allow you to know exactly when the environment is optimal.

2.2 Control the humidity

Humidity plays a key role depending on the type of food:

• Dried foods (grains, legumes, dried fruits): must be stored in a dry place to avoid mold and premature germination.
• Root vegetables (carrots, turnips, beets): keep better in a slightly humid environment (damp sand, damp ash), which prevents drying out.
• Fermented products : often require a humid but ventilated environment to maintain good microbial activity.

Tip: To adjust the humidity, you can use airtight jars, paper bags, or a slightly moistened sand/ash mixture.

2.3 Avoid direct light

Light promotes the oxidation and spoilage of food:

• Fruits and vegetables: avoid direct sunlight, favour shade or opaque partitions.
• Oils and jams: store in opaque jars or away from light to preserve color, taste and nutrients.

Tip: You can cover the clear jars with a cloth or a kraft paper bag to reduce exposure to light.

2.4 Limit oxygen

Oxygen promotes oxidation and the growth of certain bacteria:

• Dry foods (flours, grains): stored in airtight bags or sealed jars.
• Lactic fermentation: stoppers with a valve or a simple lid slightly open to let CO2 escape while limiting oxygen.
• Oils and nuts: store in airtight jars or under vacuum to prevent rancidity.

2.5 Playing with pH and salt

Fermentation, salting, and acidification are natural techniques that prevent the growth of pathogenic bacteria:

• Acidity (pH <4.5) : fermented foods such as kimchi, sauerkraut or pickles in vinegar are naturally protected.
• Salt : extracts water from cells, slowing microbial growth (meats, fish, fermented vegetables).
• Tip: Use approximately 2-3% of the weight of the vegetables for lacto-fermentation, adjustable to taste.

2.6 Preventing the development of pathogenic microorganisms

The golden rule is simple: prevention is better than cure . The techniques above all aim to:

• To slow down or stop the growth of unwanted bacteria.
• Maintain the nutrients and texture of food.
• To ensure sustainable preservation without risk to health.

2.7 Stock rotation and monitoring

Even with optimal storage, it is essential to practice food rotation :

• Label the jars and bags with the preparation date.
• Place the oldest items at the front so they are consumed first.
• Regularly check the condition of the food: smell, color, texture.

2.8 Practical examples of applied principles

Here's how to apply these principles on a daily basis:

• Apples and pears stored on shelves in a cool, ventilated cupboard: low light, stable temperature, good rotation.
• Carrots and beets buried in damp sand in a wooden crate: low temperature, controlled humidity, limited oxygen.
• Homemade sauerkraut in a jar: acidic pH, appropriate salt, lid allowing CO2 to escape but limiting outside air.
• Dried fruits and nuts: placed in airtight jars away from light and moisture.

These principles form the basis of all the methods we will detail later in this guide: fermentation, drying, salting, preserving in oil or vinegar, slow cooking, cellaring, sand, and ash. A solid understanding of these fundamentals will allow you to successfully prepare all your food and safely extend its shelf life.

3. Traditional methods for preserving food without refrigeration

A. Lactic fermentation

Lactic fermentation transforms the sugars in vegetables into lactic acid, creating an acidic environment that preserves food and enriches its nutritional profile:

• Examples: sauerkraut, kimchi, grated carrots, fermented beets, black garlic.
• Materials: glass jar, non-iodized salt, fresh vegetables and filtered water.
• Duration: 3 to 14 days at room temperature depending on the vegetable and temperature.
• Tip: Weigh the vegetables so that they remain immersed in the fermentation juice, avoid any contact with air.
• Benefits: rich in probiotics, improves digestion and immune system.

B. Drying (air, sun, dehydrator)

Drying removes water, preventing microbial growth:

• In the open air: tomatoes, aromatic herbs, mushrooms; protect from insects with a net or a thin cloth.
• In the sun: ideal for sliced ​​fruit, figs, apricots; turn regularly for evenness.
• Electric or solar dehydrator: precise temperature control (40-60°C), preserves vitamins and taste.
• Storage: airtight jars or vacuum bags in a dry, dark place.

C. Salting and smoking

Salt draws out water and limits bacterial growth:

• Meats and fish: dry salting or brining, sometimes hot or cold smoking to prolong preservation.
• Cheeses: ripened with a salted or ash-coated surface.
• Duration: a few weeks to several months depending on the technique.
• Tip: Use quality, non-iodized salt to avoid unwanted taste and chemical reactions.

D. Preservation in oil, vinegar or alcohol

• Oils: garlic, tomatoes, peppers; completely submerged, stored away from light.
• Vinegar: pickled vegetables (gherkins, red onions); acidity stabilizes preservation.
• Alcohol: cherries, prunes, pears; fruits steeped in brandy can be preserved for several years.
• Tip: always sterilize the jars and cover the fruit with a protective liquid.

E. Homemade jars and preserves

Homemade preserves are reliable if the sterilization process is done correctly:

• Sterilize at 100°C for 15-30 minutes depending on the volume.
• Shelf life: 1 to 2 years, stored in a cool, dark place.
• Examples: tomato sauces, jams, compotes, cooked vegetables.
• Tip: Check the seal of the lids, discard any jar showing swelling or suspicious odor.

F. Long cooking and confit

Slow cooking with fat creates an antibacterial barrier:

• Duck confit, rillettes, vegetables preserved in oil.
• Cook for a long time at a low temperature (70-90°C) then immerse in fat or oil.
• Duration: several weeks at room temperature or a few months in a cool place.

G. Storage in a cellar, sand or ash

Highly effective traditional techniques for growing vegetables and fruits:

• Potatoes, carrots, beets: in dry sand or clean ash, in a wooden crate.
• Eggs: buried in clean ash or covered with oil for long-term preservation.
• Pome fruits: stored on shelves, in the shade and well ventilated.
• Tip: Regularly check the condition of food and remove any damaged products.

These time-honored methods are still relevant and can be combined with modern techniques such as airtight jars, solar dehydrators, zero-evaporation containers, or passive coolers. They will allow you to preserve your food safely, sustainably, and independently , even without electricity.
