How long does egg protein powder last?

Egg protein powder is a protein supplement made from eggs, often specifically from egg whites. It is known for its high-quality protein content and is a popular choice among athletes, bodybuilders, and individuals seeking a non-dairy protein source. Like other protein powders, the shelf life of egg protein powder depends on several factors, including the ingredients, manufacturing process, storage conditions, and the presence of preservatives. Understanding the typical shelf life and proper storage methods can help ensure the product's quality and safety.

Shelf Life of Egg Protein Powder

The typical shelf life of unopened egg protein powder is around 1 to 2 years from the date of manufacture. This can vary depending on the specific product, whether it contains added preservatives, and the quality of the packaging. Most egg protein powders will have an expiration date or "best by" date printed on the packaging, indicating how long the product is expected to maintain its quality¹.

Factors Affecting Shelf Life

• Packaging: The type of packaging can influence the shelf life. Protein powders packaged in airtight, opaque containers help protect the product from light, air, and moisture, which can degrade the protein over time.
• Preservatives: Some egg protein powders contain natural preservatives, such as antioxidants, which help prevent oxidation and prolong shelf life.
• Storage Conditions: Proper storage is crucial for maintaining the quality of egg protein powder. It should be stored in a cool, dry place away from direct sunlight and moisture. Once opened, it is important to keep the container tightly sealed to prevent exposure to air and contaminants.

Signs of Spoilage

Even if the egg protein powder is within its expiration date, it's essential to check for signs of spoilage, which can include:

• Unpleasant Odor: A rancid or off smell can indicate that the powder has spoiled.
• Change in Color or Texture: Clumping, discoloration, or an unusual texture may be signs of spoilage.
• Off Taste: A bitter or unusual taste may suggest that the product is no longer fresh.

Best Practices for Storage

To maximize the shelf life of egg protein powder, follow these storage tips:

• Keep the Container Sealed: Always reseal the container tightly after each use to prevent exposure to air and moisture.
• Store in a Cool, Dry Place: A pantry or cupboard away from heat sources and direct sunlight is ideal.
• Use a Dry Scoop: Ensure that the scoop used for measuring the powder is dry to avoid introducing moisture into the container.
