Storage and Preparation of Food Supplies
Here's a tip for storing wheat. I thought it was pretty ingenious:
If wheat is not already in nitrogen-packed cans, it can be stored in sturdy 5 gallon food-grade plastic buckets or containers with tight fitting lids. If the wheat has not already been treated to prevent insects from hatching, wheat may be treated at the time of storage by placing one-fourth pound of dry ice per 5 gallon container in the bottom and then filling with wheat. Cover the wheat with the lid, but not tightly, for five or six hours before tightening the lid to be air tight.
