Vacuum preserving food . . . . Brand is "Food Saver/Meal Saver"
Bought 2 of these at the thrift store 50%-off day ($1.50 each) ...Use ZipLock vaccuum plastic bags, or use glass bottles, canning jars, etc.
Lack of oxygen (in air) helps prevent bacteria growth. A vacuum will remove most of the air (oxygen) making food stay fresh longer.
I like the "Chips Ahoy" chewy cookies as snacks.. but after a month or more they become crunchy, not chewy, because they've dried out.
.
SO, an air tight plastic bag would keep them from drying out too quickly, but... stored in a Vacuum will preserve them even longer (still chewy) and with most of the air removed, will not get stale. ... . . . With a huge open bag of Cheese Popcorn, over a month or two gets stale, absorbs moisture... so I vacuum seal most of it to keep it fresh, and keep some to eat now. The vacuum sealed popcorn will stay fresh for months.
And there are larger bags for blankets, pillows, clothing, etc which compresses them to take up MUCH less storage space.
The orange lid has a hole in it, covered with friction tape. The friction tape allows the air to be sucked out, but seals tight against air getting inside. . .. AND, you can attach the hose then suck the air out of a plastic bag of soup, stew, etc that you intend to freeze.
Creating a vacuum...
