Review on 500Cc Oxygen Absorber Packs - 50 Pack (5 X 10) By PackFreshUSA: Non-Toxic Food Grade For Long-Term Food Storage & Preservation With Guide Included by Matthew Mosley

I'm in the process of packaging flour, bisquick and cornmeal for long term storage in Mylar bag 1 gallon bags. These items contain a lot more air than rice, beans, pepper corns and therefore require a larger oxygen absorber than normally used in a one gallon bag, i.e., a 300cc packet. The 500 cc packet is just the ticket. 100 packets may seem like a lot but they are package in lots of 10 each, Use as many as you need. The remainder will stay fresh. I'm hoping to extend the self life of these goods from one year to 3 years by removing the oxygen which is the killer. Oxygen decreases self life. Also, the oxygen absorber packet will kill any weavels that may there. I've encounter that problem is freshly opened boxes of these products. Highly recommend PackFreshUSA products.
