Chilled foods can be considered part of low-impact processing (e.g., fresh, minimal processing, or pasteurization), resulting in higher quality retention, however, typically with a short shelf life that reduces product marketability. Thus, this type of products may take advantage of the hurdle concept, using the modified atmosphere packaging (MAP) as an additional preservation factor. MAP relies on modification of the atmosphere inside the package, controlled by the gas transfer through the packaging that leads to an increased shelf life. In this work, MAP overview for nonrespiring and respiring products will be presented. MAP design will be discussed. Finally, the wide applicability of this technology related to chilled foods will be described.
