How to preserve food without electricity: 5 useful tips

SSPDaily has prepared tips for preserving food quality. Find out how to extend the shelf life of food without electricity.

Storage in airtight containers

If you seal off oxygen and light, these containers can extend the shelf life of many products. For safety and quality, you should choose containers specifically designed for food storage. Proper labeling and dating are also important for keeping track of contents and expiration dates.

Use of cellars

These underground storage facilities provide cool, dark, and humid conditions that are ideal for keeping many types of foods fresh for a long time. If a person has access to a root cellar, it is recommended to use it to store root vegetables, apples, and other crops that benefit from low temperatures and high humidity.

Vacuum sealing

By removing air from the package, you slow down food spoilage and extend its shelf life. For optimal results, it is important to purchase a high-quality vacuum sealer and bags.

Fermentation

Consider fermentation as a time-honored way to preserve food without light. The natural process of fermentation can turn perishable foods such as vegetables, dairy, and grains into long-lasting foods.

Lacto-fermentation

Lacto-fermentation is the preservation of foods using natural bacteria, resulting in savory, probiotic-rich foods such as sauerkraut and pickles.
