I think if you went to the store and bought some of the comerical vacuum seald beef jerkey then check the "good untill" date you could get a prity good idea. Then I think if you double that time(most companys cut the good untill date in half just to be on the safe side) but take into concideration that they are using a comerical sealer that more than likely would be better than what you can get.
