A "map machine" refers to Modified Atmosphere Packaging (MAP) machines, which are used to extend the shelf life of food products by modifying the atmosphere inside the packaging.These machines create a controlled environment by replacing oxygen with gases like carbon dioxide and nitrogen, which slows down spoilage and microbial growth.
What MAP does:
MAP packaging works by replacing the oxygen in the package with a mix of gases, typically carbon dioxide and nitrogen. This reduces oxidation and microbial growth, which are major contributors to food spoilage.
How MAP machines work:
MAP machines typically involve a vacuum chamber where the food product and its packaging are placed. The machine then draws out the air and replaces it with a controlled gas mixture. Some MAP machines also include a sealing process to ensure a tight seal that maintains the modified atmosphere.
Types of MAP machines:
MAP machines come in various forms, including tray sealers, vacuum tray sealers, and machines for packaging in flexible pouches. They can be automated or semi-automated, and some are designed for high-volume production.
Benefits of MAP:
MAP packaging offers several benefits, including:
Extended shelf life, allowing food products to remain fresh and safe for a longer period.
Reduced food waste due to longer shelf life.
Improved product quality and appearance, maintaining the natural color and texture of the food.
Reduced or eliminated the need for preservatives.
Protection of food from spoilage and contamination.
Applications:
MAP is used for a wide range of food products, including fresh produce, meat, cheese, and baked goods. It is also used in non-food applications, such as medical products and other goods requiring a protective atmosphere.
