Food Preservation Methods

By Amy DeVries

Smart food preservation focuses on preserving the nutrients. It doesn't matter if something has a long shelf life. So does paper, and most paper is edible. But it doesn't provide the necessary nutrition for a healthy human.

The purpose of preserving food is to increase the shelf life while maintaining a high nutritional value. Most modern processed food fails to do this.

Traditional cultures knew how to preserve foods in ways that would increase the digestibility and nutrients. This is an area of great interest to me that I continue to study.

Dehydrating Food
Use the best methods for dehydrating food to avoid mold and bacteria. Drying food is a great preservation technique.

Home Canning Food
Learn when home canning food is safe, different ways to do it, and the potential dangers.

Freezing Food
Learn about freezing food, the historical use of frozen foods, and its advantages and disadvantages.

Smoking Food
You can try smoking food in a homemade smoker. Use it for curing meat or adding flavor to cheese. What will you make?

How to Freeze Dry
Nothing beats freeze drying for long-term storage. It's easy to do with the right equipment.

Each preservation technique has pros and cons. Some work better for certain types of foods or in certain climates.

The Root Cellar

You can also try using a root cellar for off the grid, sustainable preservation of your food.

My grandparents talked about storing their vegetables in the root cellar and basement. There were big barrels of sauerkraut down there. They even used it as a place to age meat so that it would last longer without electric refrigeration.

Cold Storage for Food Preservation

The problem with modern basements is that they're too warm. In the days before the central heating furnace and good insulation, the basement stayed cold and dark.

To recreate the proper environment, some people dig a cellar as a separate room in the ground separated apart from the house.

This isn't as useful as a cold basement because you would have trouble getting to a separate root cellar in bad weather such as ice or deep snow.

Mini Cold Storage

Another alternative is to use straw in a barrel sunk into the ground. The barrel or container should be deep enough to go below the frost line or the depth that the ground freezes to in the winter.
