sorry i don't off hand :(. mostly it was trial, error, and googling. If i buy something from costco and it doesn't last i would try different was to store it and if none work just stopped buying it. really only couldn't get blackberries and raspberries to keep long thou.

suggest getting commercial food storage bins, they stack and can seal in moisture, great for storing something like sliced peppers. Don't just toss everything in with the package they came in, do a little prep and get them in better containers. If things go moldy paper towel does wonders to manage moisture.

as for vacpack i got a good commercial one, and then put it in another room out of the way. i prep in the kitchen then i take it over to seal. it would be a lot of counter space but its not so bad in the corner of my office. Also i only use it for ingredients like meat. soups and sauces i just toss in glasslocks and freeze as they seem to do just fine that way.
