MAP Leads Fresh Food Preservation Methods

Modified Atmosphere Packaging is prevalent among participants of a new PMMI Business Intelligence report, but technologies such as High Pressure Processing (HPP) are continuing to expand as well.

According to “2019 Trends and Advances in Food Packaging and Processing,” 64% of food manufacturing companies interviewed are using MAP (Modified Atmosphere Packaging) to preserve food and extend shelf life.

The FDA says MAP "involves either actively or passively controlling or modifying the atmosphere surrounding the product within a package made of various types and/or combinations of films." Active MAP substitutes the atmospheric gases in a package with a desired mixture of gases to preserve freshness, while passive MAP develops a desired atmosphere naturally through the use of a selected film type and the resultant respiration and diffusion of gases through the film.

There are continued innovations in MAP, such as a new system introduced in the UK that vaporizes natural aromas, like essential oils, and mixes them into the MAP gas with no extra steps or safety concerns, in an effort to enhance a consumer’s sensory experience.
