I saw in the news the other day that a lot of our meat is treated with CO2 to preserve it and retain the red color. I was wondering if any of you guys that have vacuum sealers would know if it would be possible to convert them to inject CO2 prior to vacuum sealing your bait? Where would a person go to get a tank of CO2? Could you just use dry ice and get the same effect? Sounds like it maybe be some work to set up a process but if it would work to keep bait from times of plenty it might be worth it. Just thought this might be a good brotherhood project.
