Air in vacuum-sealed frozen fish?
Has anyone else experienced this? I purchased wild haddock from Costco, and I’ve noticed that many of the individually packaged fish aren’t properly vacuum sealed — they contain air inside. I assume this only impacts freshness, right?
Yes, it’s not uncommon for vacuum-packed frozen fish to have some air inside the package, even if it’s labeled as vacuum sealed. Air pockets can form during the packaging process, which can lead to freezer burn and affect the freshness and texture of the fish over time. If there’s too much air, it could indeed impact the quality, flavor, and overall freshness when you thaw and cook it.
If you notice that the fish has been exposed to air or looks freezer-burnt, it’s a good idea to use it sooner rather than later. To help prevent this in the future, you might consider re-sealing the fish yourself using a vacuum sealer or wrapping it in plastic wrap followed by aluminum foil before freezing. This can help minimize air exposure and maintain the quality. If you’re ever unsure, checking the packaging for any visible damage or leaks is also a good practice!
