Modified atmosphere packaging (MAP) replaces the air inside a food package with a controlled gas mix — usually CO2, N2, and O2 — to slow spoilage and extend shelf life. This answer defines the method.
| Gas | Role |
|---|---|
| CO2 | Suppresses microbes |
| N2 | Displaces oxygen |
| O2 | Keeps produce fresh |
| Mix | Matched to food |
