I recently was cleaning out some old boxes and found a lot of vacuum seal bags that I had bought a few years ago. I am thinking about buying some rice and dried beans and vacuum sealing them in the bags in the proportion for one meal sizes for my family, that way just cut open a bag and not have to open and shut one big bag. I have a case of these things so I won't run out anytime soon. If I threw in an oxygen and desiccant pack, would they be fine touching the stock? I know beef jerky has them but I didn't know if there is a certain type of bag they need to be in. The desiccant bags that I get are the tyvek wrapped kind. What kind of shelf life would be expected doing this?
