Packaged food articles of improved appearance and stackability are described such as a refrigerated active cultured dairy product. The articles comprise an unpressurized, imperforate container having an opening fabricated from a material having a low gas permeability, a quantity of gas releasing food stuff disposed within and partially filing the container defining a headspace such as a live cultured dairy; a peelable flexible seal membrane overlaying and sealing the opening; and an initial headspace gas that is enriched with the gas. Processes for preparing packaged food articles that are resistant to bowing of the flexible membrane by internally release gas comprises the steps of: providing an unpressurized, imperforate container having an opening fabricated from a material having a low gas permeability; Filing the container with a quantity of gas releasing food stuff to partially fill the interior volume defining an unfilled headspace volume; adding a quantity of the gas to the unfilled headspace volume of the container to form an initial gas enriched headspace; and, immediately thereafter sealing the container opening with a flexible seal membrane to form a packaged food article having an initial headspace enriched with a gas. The headspace initial gas enriched headspace has an enriched gas content of about 5% to 40%.
