Yes, there are several reasons why storing AGN Roots Grass-Fed Whey in the freezer offers long-term storage benefits; at the top of the list, storing whey in a freezer will increase the shelf-life and slow down the degradation of less stable components. The least stable component in AGN Roots is the emulsifier sunflower lecithin.
There are distinguishing caveats that will make or break a successful long-term storage plan in a freezer. It's essential to understand that the AGN Roots package is not a single material but several independent custom layers that collectively provide the following attributes designed explicitly for nutrient preservation -
UV Barrier
Thermal insulator
Tear-resistant nylon layers
These layers' design and collective compatibility are temperature dependent and unpredictable in long-term sub-freezing conditions. In this case, the increased risk of material separation and loss of seal integrity makes the pouch less desirable for long-term freezer storage.
We recommend transferring the product from the original flexible pouch into a more fit-for-purpose solution, for example, using a vacuum sealer and food-grade PET or freezer bags. Vacuum sealing is preferred to eliminate the possibility of forming condensation resulting from unintentional temperature variation (power outage) paired with trapped humidity.
If a vacuum sealer is not in your toolbox, please consider using oxygen absorbers that can be inserted into a freezer bag. Once the whey and oxygen scavengers are in a freezer bag, the most critical task is to seal the bag.
