The pouch containing our whey is designed with a custom 7mm barrier explicitly intended for the journey from production to delivery; this includes a wide range of climate exposure.
Pouch Details: Each layer is designed for a specific purpose; we utilize transparent foil (thermal protection), a UV barrier film (direct sunlight exposure), nylon (puncture & tear resistance), and several alox layers for gas-tight food-grade protection against moisture. A high-density inert plastic (HDPE) that lines the inside of our pouches is the contact layer and is considered best in class for food safety (industry norm).
Known Issues with Whey - Whey is considered hygroscopic and can pick up ambient humidity and moisture when shipped in a rigid PET tub or non-air-tight pouch. The impacts of condensation forming inside a non-airtight pouch of dry powder can be devastating regarding microbial growth.
Pouch Tolerance – The AGN Roots pouch can withstand temperatures up to 140°F without external protection (shipping box), a condition that rarely exists. For transatlantic shipments, during summer months, climate-controlled technology is used to combat potential deck temps of a sustained 160°F; this is hard to recreate in the last mile of fulfillment.
Distribution - Our inventory is distributed nationwide, and the last-mile fulfillment quality varies from state to state. Undergoing preservation-based processing, AGN Roots has a higher moisture content (< 6%) than most (industry standard is 2% or less, i.e., dust).
Hot Climate Expectations - Moisture (in gas form) may rise to the top of the pouch head, leading to a distinct warm dairy smell when opening. Any expanded dairy gas will mix with the nitrogen to displace the air before sealing. If you receive the pouch and it is warm, allow the pouch to cool and let any trapped gas escape. The protein is highly stable in its dehydrated state (all bets are off once you add water or open the bag to the environment); it would take prolonged exposure to temperatures that exceed what is presumed capable in the back of a delivery truck or on a porch.
