How To Preserve Eggs Without Refrigeration?

In this brief guide, we are going to answer the question “How to preserve eggs without refrigeration?”, and discuss the different methods of preserving eggs without refrigeration and the potential implications of preserving eggs without refrigeration.

How To Preserve Eggs Without Refrigeration

You can preserve eggs without refrigeration by keeping them cool in the root cellars, preserving them in slack lime or beeswax, salt curing the yolks, making them into dried egg pasta, salt curing the whole eggs, pickling them in vinegar or alcohol, etc. 

Keeping eggs in the root cellar

A root cellar provides cooler temperatures for egg storage without power. Unwashed eggs are seen to last for 2-3 months in root cellars.

The duration of unwashed eggs lasts outside a refrigerator depending on the temperature and humidity levels in the storage space. Ideally, a temperature below 50 degrees F ( 10 degrees C.) and humidity of around 75% is used. Maintaining these conditions is found to be more challenging in warm and arid climate zones.

Turning the stored eggs over regularly in the cool storage can also help to preserve them (it will stop the upper part of the shells from drying out so quickly).

Preserve eggs in slack lime

Coating eggs in different substances slow down the process of the shells drying out and gives them a new protective coating.

Many different coatings have been suggested and shown with variable results such as:

  • mineral oil
  • butter or lard
  • vaseline
  • sodium silicate
  • isinglass (from the swim bladders of fish)

 One of the options seems to be using slack lime ( lime hydrated with water). Slaked lime seems to be available at building supply stores. Mixing slack lime with water gives a solution that can be used to coat the eggs. This coat does not affect their flavor or cause any negative health effects.

Preserve eggs in beeswax

Coating eggs in wax is another way to seal the pores on fresh eggs to preserve them longer and prevent spoilage. This is known to be a more eco-friendly and natural solution. Using beeswax is rather a better option than using paraffin wax for this purpose.

Eggs coated in beeswax should be kept for several months. However, keeping them in a root cellar or another cool space after the wax coat is a better and safe option.

Preserve eggs as dried egg pasta

Another traditional way to preserve eggs for the long term is to dehydrate them. Dried egg is shelf-stable.  Dried egg powder can be used in a range of different ways. Dehydrating eggs at home is found to be rather tricky. Often greasy, grainy, unpleasant results are reported by people who try it.

One easy solution to use up and preserve fresh eggs is to use them to make some shelf-stable dried egg pasta. Use up a lot of eggs, take eggs and break them. Make a big batch, dry it, and store it in the pantry. In drier climates, air-drying of pasta is done. But the best way to dry the pasta is to use your oven or a dehydrator where there is higher humidity.

Salt Cure Egg Yolks

Salt curing is another method that can help create fermented eggs. Fermentation of hard-boiled eggs in saline brine along with a little sauerkraut juice or whey does it all. Making salt-cured egg yolks seems to be an interesting way to preserve fresh eggs for only about 3-4 weeks. The salt-cured yolks can be used as a parmesan substitute, grated, and used in various dishes.  When cured in salt and sugar, a new something is created, something a little different that can be grated over salads or used to top a variety of desserts.

 Looking into the Chinese delicacy, salt-preserved whole eggs which are then hard-boiled, are traditional. To go for something pretty new, salt-cured yolks could be an interesting thing to try.

 Other methods of preserving eggs without refrigeration

 Various other methods can be used for preserving eggs without refrigeration. Some of them are:

  • Pickle  eggs in vinegar

Pickling eggs in a vinegar solution can allow them to preserve them for up to around 3-4 months at cold temperatures. Since the vinegar may not reach the heart of the eggs, they are prone to botulism. Thus, it is suggested to quickly use canned or pickled eggs.

  • Preserve eggs in alcohol

Using a lot of alcohol will kill off bacteria. This stops the fresh produce in the drink from going bad. It becomes important to keep it in a cool place to keep it for any length of time.

  • Make curds for canning

Canning helps to keep the eggs for several months or even up to a year. . As long as the correct canning procedure is followed, this process is a safe and sensible way to preserve some fresh eggs.
