you might try nitrogen flooding.
A square inch is more than enough to do a 5 gallon bucket. I wrap it in a paper towel prior to putting it in the bottom of a bucket. Im eating wheat stored 15 years ago this way and Its real hard to tell the difference from last years crop. Could you please elaborate how dry ice that is sold to keep food cold will adversly affect food? Nitrogen purging would be ideal but would require some equipment. I would buy the absorbers before buying a tank and valves. frozen Co2 displaces the air as it turns to gas as it is heavier. Dry ice because it it is a solid requires no investment in tank and valves, shake and bake. Nitrogen would be better as it is more inert but dry ice has worked very well for me as mentioned. I have never opened a bucket to find it full of bugs. I had not considered contamination of the dry ice though and had I I probably would have sprung for absorbers.
