All of our product packages are of the highest quality, custom manufactured to protect the valuable contents. With our vast research, 150 micron mylar walls protect our food almost indefinitely.
With a food-grade oxygen absorbing packet, all initial oxygen is removed during the packaging stage. Completely void and protected from oxygen, moisture, and light, our products will last pretty much indefinitely. It is always best to store our products (and everything else you store) in a cool, dry, dark environment without any severe environmental fluctuations.
Although completely safe in the trunk of your car in +30 degrees C or -50 degrees C, the severe fluctuations will compromise the integrity of the package over time, which can then compromise the contents. Severe heat may destroy some of the food value that freeze dried food offers, turning it more into a dehydrated-quality food. Extreme severe heat (30+C) can actually melt certain characteristics in the food, such as sugars in the Freeze Dried Smoothies, causing clumping to occur. Amazingly, the food would still not be spoiled, but have less nutritional values and may be harder to prepare.
For storing for only a few years, store anywhere you like. The more stable the environment the better. If you are planning on consuming our products 25, 30, or 50 years from now, store in the most stable environment you can (Cool, dark, and dry conditions).
We do simple tests with our products, including leaving prototypes in various extreme environments to test how they hold up. We have left prototypes outside in the summer time, and outside in the extreme cold winters. We do not recommend storing products in any extreme conditions; this is for research purposes only.
Our packaging is such high quality that when a high-power flashlight is put directly against the packaging, little or no light gets through. For moisture, you could throw our products in a lake and find them a month later to find that the contents are still moisture-free and ready to eat!
