How to preserve eggs? (3 ways)

In this brief guide, we are going to answer the question “How to preserve eggs?”, and discuss the different methods of preserving eggs and the potential implications of preserving eggs.

How to preserve eggs?

You can preserve eggs by a variety of methods. These are:

  •  refrigerating them for short-term use
  •  freeze-drying them
  •  salt preserving them
  • coating the eggs with mineral oil, etc.

Eggs are very nutritious as they are protein-rich food. Eggs help in the growth of the body. Thus, eggs must be preserved in order to make use of them in different dishes.

Refrigeration of the eggs

  • Eggs can be stored for up to 2 to 3 months at temperatures below 55°F without any other intrusion in their storage.  
  •  It is required to carefully monitor the humidity. The humidity is seen to be consistently close to 75%. 
  • If humidity levels go too low, the eggs are seen to dry out; if the humidity is too high, the eggs sometimes go moldy.
  • It is of great importance to use only clean, uncracked eggs. 
  • Washing off or dry buffing an egg removes the protective outer coating, which in turn allows bacteria to more easily enter the egg, causing spoilage.

Thus, direct refrigerating of the eggs is an easier method of short-term preservation of the eggs.

Coat eggs with mineral oil for long-term storage 

Coating the egg with oil helps to seal the shell to prevent evaporation during storage. The eggs to be stored this way should be oiled and stored within 24 hours of being laid. This shows that it is not convenient to oil and save store-bought eggs for the long term.

The process involves:

  •  Eggs used must be dry and at room temperature.
  •  Mineral oil should be free from bacterial and mold contamination ( achieved by heating it to 180°F for 20 minutes.
  • With tongs or a spoon, the eggs are dipped one at a time in the oil.
  •  Then eggs are kept aside on a metal drying rack to let drain for about 30 minutes. 
  • After they are completely dry, search for a clean, dry carton and pack them away.
  •  Finally, eggs are stored in a cool, dry place.
  • This makes them stay for several months.

Salt preservation of eggs

Salting is another easy way to preserve fresh eggs. For this, fresh eggs should be used which have not been cleaned. If they age more than 24 hours, chances of success diminish rapidly. Also, exposure to extreme heat or cold will hinder the preservation process. 

The eggs can be stored in salt or other finely ground preservatives such as bran, or an equal mix of finely ground charcoal and dry bran, or finely ground oats.  They can also be stored in finely ground plaster of Paris. The salt and bran can be fed to the cattle after use.

Precautions to be taken:

  • The eggs are stored small-side down. 
  • Also, the eggs can be stored layer upon layer, as long as they don’t touch each other, or metal, or wood. 
  • There must be enough finely ground preservatives to pack them in well.
  • Store them in a covered container and keep them in a cool, dry place. 
  • Do not allow the eggs to be exposed to freezing temperatures, as this will rot the eggs quickly.

 Properly prepared and taken care of, these eggs will keep “fresh” for about 8 to 10 months. Some countries are known to have stored their eggs in this way for up to 2 years.

Freeze the eggs

Eggs can be frozen in freezer bags, mason jars, plastic containers, and ice cube trays. These frozen eggs act much like the fresh version when thawed and used. 

Steps involved in freezing:

  • Break the eggs into a bowl.
  • Beat through a strainer to combine the yolks and whites.
  • Pour them into the container and freeze( pour the eggs into an ice cube tray).
  • Once the eggs are frozen,  they are removed from the tray and placed in a freezer bag.

 Freezing eggs in smaller amounts in an ice cube tray helps in quick thaw and helps in the preparation of a real quick meal.

Dehydrate the eggs and powder them

  • The trays are lined in the dehydrator with parchment or wax paper.
  • The parchment papers are folded up from all the edges to form a tray so the liquid eggs won’t slide off the tray.
  • The eggs are broken and stirred to combine or separate and dry the whites and yolks on two different trays.
  • The eggs are slowly poured onto the tray, the eggs are pulled to the edges of each tray. A very thin layer is made so that they dry evenly.
  • Dehydration is done at 135°F for 6 to 8 hours or until no moisture is left. 
  • The eggs are stirred about halfway through to avoid the skin forming on the top and outside edges.
  • Once dried, the eggs are crumbled and stored in a jar with a tight-fitting lid, or grind or blend the crumbles into a powder.
  • The eggs are reconstituted with hot water and then cooked as normal.
