Shelf Life

Remember, properly stored rice, wheat, oats, beans will last longer than anyone prepping will likely live and still be nutritious. 

By properly stored, the items have to be repackaged into food safe containers, preferably sealed in mylar to block light which degrades the items and then the oxygen needs to be removed or reduced.

You can remove the oxygen in several ways, the easiest by far is to use O2 absorbing packages which are pretty cheap and readily availalbe.  Go overkill with them.  Why risk 30 pounds of wheat by trying to save 25 cents by putting in one less O2 absorber.

When we repackage our food into 5 gallon food grade buckets, NOT buckets with just HDPE #2 on them but ones guarenteed food grade, take the recommendation on O2 absorbers which knowing the market like I do are overkill to sell more product and then add 20% more in absorbtion quality. 

If 4 500cc O2 packages are recommended for a 5 gallon bucket of wheat or rice, I put in 5.  At what I pay for them, that's 25 cents more per bucket.  Do you really want to risk opening that bucket of rice 10 years (or next month) down the road and find it filled with dead weevils and egg husks and no wheat because you cheaped out on a quarter?

Those #10 cans of dehydrated foods, packed with 02 absorbers or nitrogen flushed, there are numerous reports o them being opened 10, 20 even 30 years later and being perfectly good and just as tasty as they were the day they were canned.

Just like you pay house, care, life, health insurance, pay a little here and there and set up society insurance.   Just like the others, it's hopefully wasted money, but those times it turns out to not be wasted, there is no substitue.
