I don't think you guys are taking my comments in the spirit intended. I am actually quite interested in the vacuum bagging experiments. For sure certain packing helps slow aging so I'm sure bagging up your boxes is working. Being an engineer, I like to understand the mechanism at play.
I also like to fish and packing fresh fish is something where getting as much vacuum as possible helps keep it fresh for a very long time. The guys who do that regularly use chamber vacuums and THICK bags to get nearly a full vacuum before sealing. It makes a big difference over the food saver machines. But even those leak over time.
As I said earlier, it would be an interesting experiment to use a commercial housing and REALLY pull a full vacuum. Unfortunately for all of us, by the time we understand that impact it will probably be a long time from now.
