I once got a 10KG sack of rice from an Asian store once. After a year it got full of tiny bugs less than 1mm in size. Now I buy 1kg bags that I can more easily seal airtight with pegs.

I divide the 10kg sack into a bunch of mason jars and avoid the pests.

Thats the correct way to go about it really. I will do it this way next time.

Buy a canning funnel!

But you're missing out on all that extra protein!

For bulk foods, like grains, you can use aluminized polyester film bags, and blow in pure nitrogen or drop in an oxygen-absorber packets while sealing the bag. Then you put the bags in a food-grade bucket and seal it. The bags can have resealable zip-locks on them.

Yes, this uses plastic, but all of it is reusable when using certain bag-sealing methods.
