Moisture and Oxidation Effects

Moisture is a major concern for pea protein preservation. High humidity levels can lead to clumping and create an environment conducive to bacterial growth.

Oxidation occurs when protein molecules react with oxygen, causing rancidity and nutrient loss. This process is accelerated by moisture, heat, and light exposure.

To minimize these effects:

• Use a clean, dry scoop when measuring protein powder
• Close containers tightly after each use
• Consider using desiccant packets to absorb excess moisture
• Avoid storing in humid areas like bathrooms

Storage Conditions and Packaging

Proper storage conditions and packaging play crucial roles in maintaining pea protein quality. An airtight container is essential to prevent moisture ingress and oxidation.

Opaque containers offer better protection against light exposure than transparent ones. Some manufacturers use metalized bags or dark-colored jars for this reason.

Packaging materials matter:

• Glass jars provide excellent barrier properties
• High-quality plastic containers can be effective if BPA-free
• Resealable bags should be fully sealed after each use

Temperature stability is key. Aim for a consistent, cool environment between 50-70°F (10-21°C). Refrigeration isn’t necessary but can extend shelf life in hot climates.

Added ingredients like preservatives may help prolong shelf life, but many consumers prefer clean-label products without additives.

Proper Storage Techniques

Storing pea protein powder correctly is essential for maintaining its quality and extending its shelf life. The primary goals are to protect it from moisture, light, and air exposure.

Use an airtight container to store your pea protein powder. This prevents humidity from causing clumping and preserves the powder’s texture and nutritional value.
