Overview

E938 - Argon

Argon (E938) is a colorless, odorless noble gas used in food packaging to protect products from air. It fills the headspace in packs and bottles to push out oxygen, helping keep flavors, aromas, and textures intact. Because argon is inert, it does not react with the food itself.

E948 - Oxygen

Oxygen (E948) is a colorless, odorless gas used in food packaging to help keep some foods looking and tasting their best. In “modified atmosphere packaging” (MAP), it can be added to the headspace of a pack, especially for red meats, to support a bright, appealing color and maintain product quality. It is the same oxygen found in air, but supplied at food-grade purity for safety.
