Step 1
Modified atmosphere packaging
Answer
Modified atmosphere packaging (MAP) involves the removal of air from the package and replacing it with a controlled mixture of gases, typically carbon dioxide, nitrogen, and oxygen. The package is then heat sealed to prevent any re-entry of air. This process helps to slow down the growth of spoilage organisms such as bacteria, yeasts, and molds that can cause food to spoil. By creating an environment that is less conducive to the growth of these microorganisms, modified atmosphere packaging significantly enhances the shelf life of food products, thereby preserving their freshness and quality.
Step 2
Biodegradable packaging
Answer
Biodegradable packaging refers to materials that can break down naturally into raw materials found in nature. For example, biodegradable packaging might consist of materials such as paper bags or cardboard. These materials decompose through the action of living organisms, typically bacteria, fungi, or other microorganisms, within a reasonable time frame. This type of packaging is beneficial for the environment as it reduces waste and minimizes the carbon footprint associated with non-biodegradable materials.
