Seeds, grains, & beans are living organisms. Just like people & animals, if they're stored in oxygen deprived environments, they... will... die... They'll still be ok to eat, but they won't be able to sprout or grow afterwards. What I would suggest is this:
Pack some of your seeds, grains, & beans with oxygen absorbers, and pack the rest without. Remember to label them "with" or "without". This way, you'll always know which ones are alive & good for sprouting (or planting in a garden). And which ones are only o.k. for cooking & eating.
Of course, sprouts are great for every day use - but in an emergency, if you don't have access to vegetables, sprouts are vital as a substitution for this. In fact, once they are sprouted, they're pretty much considered a vegetable - because the nutrition content is boosted up to 600 times depending on what you're sprouting. This is especially true for wheat / wheat sprouts / wheat grass.
So don't forget to keep a good supply of your living seeds, grains, & beans in an environment where they can STAY alive!
