A modified food storage is called a?

There isn't a single, universally accepted term for a "modified food storage." It's a broad concept, and the specific term will depend on the type of modification being used. Here are some possibilities:

* Modified Atmosphere Packaging (MAP): This involves altering the gas composition inside the packaging to extend shelf life.

* Vacuum Packaging: Removing air from the package to slow down spoilage.

* Sous Vide: A cooking technique that involves sealing food in vacuum bags and then cooking it in a water bath, which also extends shelf life.

* Irradiated Food: Exposing food to radiation to kill bacteria and extend shelf life.

* High-Pressure Processing: Using high pressure to kill microorganisms and extend shelf life.

* Aseptic Packaging: Sterilizing both the food and the packaging to extend shelf life.

* Freeze-Drying: Removing water from food by freezing and then sublimating the ice, allowing for long-term storage.

If you could provide more context about the specific modification you're interested in, I might be able to give you a more precise answer!
