What is Egg White Powder?

Egg white powder is a dried and powdered form of egg whites that offers many benefits compared to fresh egg whites.

What is Egg White Powder

It has a longer shelf life, is easier to store, and can be used in a variety of recipes and applications.

Egg white powder is made by separating eggs into yolks and whites, pasteurizing the whites, and then spray drying them into a fine powder.

How Egg White Powder is Made

The process of making egg white powder starts with farm-fresh eggs. The eggs are cracked open and the yolks are separated from the whites. The egg whites are then pasteurized, typically using heat between 130-140°F for several seconds up to 4 minutes maximum. This step kills any potential bacteria present while avoiding overcooking the proteins.

After pasteurization, the liquid egg whites are pumped into an atomizer that breaks up the liquid into a fine mist. This mist is sprayed into a heated chamber, where the hot air rapidly evaporates the moisture. What's left behind is a very fine, dry powder. Additives like acids or anti-caking agents may be added in minimal amounts to improve flow and prevent clumping.

Benefits of Using Egg White Powder

Egg white powder offers several advantages over fresh egg whites:

  • Long shelf life - Powdered eggs can last 12-24 months when stored properly, versus 2-4 weeks for fresh eggs.
  • No refrigeration needed - The powder can be stored at room temperature until opened.
  • Reduced food waste - Powder has less spoilage compared to fresh eggs.
  • Convenient - Easy to store and portion compared to cracking fresh eggs.
  • Versatility - Can be used in place of fresh egg whites in many recipes. Reconstitutes well into liquid egg whites.
  • Reduced egg allergen - The powder contains no egg yolk allergens.

Nutrition Profile of Egg White Powder

Egg white powder is an excellent source of high-quality protein:

  • 80-90% protein - Mostly albumen protein with all essential amino acids.
  • Low fat and carbs - Less than 1 gram of fat and carbs per serving.
  • No cholesterol - All the cholesterol is contained in the yolks.
  • Gluten-free and dairy-free

Egg white powder contains minimal amounts of vitamins and minerals from the egg whites. It can be an easy way to add extra protein to smoothies, baked goods, or other recipes.

Uses for Egg White Powder

Egg white powder can be used as a substitute for fresh egg whites in many recipes:


  • Meringues
  • Macarons
  • Cakes
  • Muffins

  • Omelets
  • Quiches
  • Soufflés
  • Frittatas
  • Foams
  • Hollandaise sauce

Key Takeaway: The powder reconstitutes into egg whites that can be scrambled, fried, or used in cooked recipes needing egg binding and structure.

  • Marshmallows
  • Homemade pasta
  • Glazes and icings
  • Meat binder

How to Reconstitute Egg White Powder

Reconstituting the powder into liquid egg whites is easy:

  • Use approximately 1 tablespoon (8-12g) powder + 2 tablespoons (30ml) water per egg white equivalent.
  • Put the powder in first, then gradually whisk in the water. Avoid adding too much water.
  • Let sit 1-2 minutes to fully hydrate, then whisk again until smooth.
  • For foams and whipping, chill reconstituted whites before whipping.
  • Add cream of tartar or lemon juice to help stabilize foams.
  • Don't overbeat, as it can thin out the whites.

Key Takeaway: Using the right powder to water ratio and avoiding overbeating creates egg whites that perform similar to fresh egg whites.

Storing Egg White Powder

Follow these tips for properly storing egg white powder:

  • Store powder in an airtight container in a cool, dry place. Avoid humidity.
  • Shelf life is up to 2 years unopened or 1 year opened.
  • Close tightly between uses to maintain freshness as powder can absorb odors.
  • For optimal freshness and shelf life, consider refrigerating opened powder.
  • Do not freeze the powder, as this can negatively affect texture.
  • Discard if powder becomes discolored or smells bad.

  • Nothing beats super fresh eggs from a farmers market or local farm.
  • Some dislike the mildly processed flavor of powdered eggs.
  • Reconstituting adds an extra step compared to cracking whole eggs.
  • Less environmentally friendly due to processing methods and packaging.
