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

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.

- Raw egg whites are sometimes preferred for cocktails or health shakes.
- 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.
FAQs
Is egg white powder safe to eat raw?
No, always cook egg white powder before eating. Unlike fresh raw eggs, powder is made from pasteurized egg whites and not intended for consumption without cooking.
Does egg white powder taste different than fresh eggs?
It can have a slightly different flavor, but when mixed into recipes most people don't notice a difference. Start with less powder and increase if needed.
How long does reconstituted egg white powder last?
Reconstituted powder should be used right away rather than storing for long periods. It will last 2-3 days max refrigerated.
Can you use egg white powder to make aged egg whites?
Unfortunately no, aging requires fresh raw egg whites. The pasteurization process prevents effective aging.
Is egg white powder gluten-free?
Yes, eggs naturally contain no gluten so egg white powder is inherently gluten-free. Just check labels for any possible added ingredients.
Conclusion
Egg white powder is a versatile pantry staple offering the benefits of egg whites in shelf-stable powder form.
While not exactly the same as fresh egg whites, it reconstitutes well into liquid egg whites suitable for cooking and baking.
Egg white powder saves time and cuts down on waste compared to fresh eggs. Just be sure to buy high-quality powder and store it properly.
