Well I ended up vacuum sealing it...so I hope it works. I have a vacuum packer I use for sealing fish to put in the freezer. I assume it's the same as the plastic bag sealing.
vacuum sealing is the same whatever it's used for. use a decent plastic bag, put item in bag, remove as much air as possible, seal it up by melting the open ends of plastic.
see how it goes and update us updated on if it works
