  1. Freezing
  2. Freeze-drying
  3. Dehydrating
  4. Mineral oil method
  5. Water-glassing
  6. Pickling

How to preserve eggs by freezing

Freezing is used to preserve both raw and cooked eggs. However, eggs must not be frozen in their shells. Frozen eggs can be thawed in a container in the refrigerator overnight. Thawed eggs must not be refrozen.

To freeze raw scrambled eggs:

  • Lightly scramble the eggs.
  • Add sugar or salt. If salt or sugar is not added, the egg yolks will thicken during freezing.
  • Pour into muffin trays or ice cube trays and freeze them for a few hours.
  • Transfer into ziplock bags, label and place them back in the freezer.

To freeze cooked scrambled eggs:

  • Cook scrambled eggs and allow them to cool down to room temperature.
  • Wrap the eggs in plastic wrap and remove all air.
  • Place the plastic wrap inside a ziplock bag or cover it with foil.
  • Label and place it in the freezer.
  • Cooked scrambled, frozen eggs must be used within 1 year.

Freezing separated eggs: Egg whites and yolks can be frozen separately.

To freeze egg whites and yolks separately:

  • Separate eggs into whites and yolks.
  • Lightly stir the egg whites and yolks separately. For egg yolks, add sugar or salt to prevent thickening.
  • Freeze them in an ice cube or muffin tray.
  • Transfer into ziplock bags, label and place them back in the freezer.

How to preserve eggs by freeze-drying

Freezing allows the preservation of the proteins and nutrients in eggs for a long period. The main drawback of freeze-drying is that it requires a freeze dryer.

Both cooked and raw scrambled eggs can be freeze-dried. Freeze-drying preserves 97℅ of the nutritional value in eggs for about 25 years. To obtain the best shelf-life from freeze-dried eggs, they must be stored in an airtight container in a cool and dark place. It is also recommended to add an oxygen absorber.

Freeze-dried eggs can be used as a substitute for freshly cracked eggs in baking, scrambling and even as an egg wash.

How to preserve eggs by dehydrating

Eggs can be scrambled or hard boiled and then dehydrated using an oven or a food dehydrator. After dehydration, eggs can be ground to a powder in a food processor. Dehydrated and powdered eggs can be stored in an airtight container or vacuum-sealed.

Home-made dehydrated eggs can last for about a year. If frozen, dehydrated eggs may last for about 5 years. (Wiki link)

How to preserve eggs by using mineral oil

Eggs coated with mineral oil will preserve for about 3 months at room temperature and up to 1 year when refrigerated. The advantage of the mineral oil method is that it can be used to preserve whole raw eggs.

To preserve eggs will mineral oil:

  • Clean and dry whole raw eggs.
  • Warm-up mineral oil.
  • Rub mineral oil over the whole eggs.
  • Place the mineral oil-coated eggs in a dry carton with the small end down.
  • Gently flip the egg carton either monthly or weekly. This is done to keep the yolks intact.

How to preserve eggs by water-glassing

Water-glassing is a unique method used to preserve eggs. Water-glassing preserves whole, raw eggs for 12 to 18 months. 

The disadvantage of water-glassing is that it can be done only on farm-fresh, unwashed eggs with the bloom intact. Eggs bought from supermarkets and groceries cannot be preserved by water-glassing since they have already been washed and bleached. 

Water-glassing is a quick and efficient method of preservation requiring only farm fresh eggs, distilled or spring water, pickling lime and a food grade bucket or a container. During water-glassing, the eggs are immersed in a mixture of distilled water and lime and kept in a cold dark place until needed. 

Eggs removed from the mixture must be washed and kept in a refrigerator if they are not immediately used.

How to preserve eggs by pickling

Hard-boiled eggs can be preserved by pickling. Pickling is done by submerging hard-boiled, peeled eggs in a solution of vinegar, sugar and a choice of spices. Hard-boiled pickled eggs will last for about 3 – 4 months when refrigerated in an air-tight jar.
