Is vacuum sealing the same as canning?

No. Oregon State University Extension (source material by UGA extension food specialist Elizabeth Andress) says vacuum packaging does not replace the heat processing of home-canned foods, and does not replace refrigerating or freezing foods that need it.

Can vacuum-sealed food go bad at room temperature?

Yes. Some pathogens, including Clostridium botulinum, can grow in low-oxygen, moist, low-acid food at room temperature without obvious signs, per Oregon State Extension. Low-acid vacuum-packed foods that aren't otherwise shelf-stable need refrigeration at 38-40°F or freezing.

What's the difference between a chamber sealer and a regular vacuum sealer?

An edge (external) sealer pulls air out of a textured bag at the seal bar. A chamber sealer puts the whole bag inside a chamber, which lets it seal liquids like soups and marinades, per the chamber sealer listings.

Quick answerFor freezer storage, a FoodSaver with built-in roll storage is the easy default: the FM2100 covers the basics and has an accessory port for jar sealers. If you seal a lot of wet or marinated food, look at Anova's Pro with its wet mode. Processing deer or bulk meat? The Weston Pro-2300 has a fan-cooled motor built for continuous use.

A vacuum sealer pulls air out of a bag and heat-seals it shut. For dried food, NCHFP calls vacuum packaging “a good option.”

What vacuum sealing is notIt's not canning, and it's not a substitute for the fridge or freezer. Oregon State University Extension (source material by UGA extension food specialist Elizabeth Andress) warns that some pathogens, including botulism bacteria, grow well in low-oxygen, moist, low-acid food at room temperature, often with no warning signs. Low-acid vacuum-packed food that isn't otherwise shelf-stable needs refrigeration at 38–40°F or the freezer.

What to look for

Moist/wet mode. Juicy meat and marinades can get pulled toward the seal bar. A moist mode helps.
Double seal. Two seal lines are a backup against a leaky bag.
Roll storage and cutter. Making custom-size bags from a roll cuts waste.
Accessory port. Lets you use a hose with jar sealers and canisters. See vacuum sealing mason jars.
Continuous use. If you seal dozens of bags in one sitting, look for a model the maker says is built for continuous use.
