Quick Answer
Packaging of freeze dried meals is crucial for extending their shelf life, as moisture and oxygen can compromise the quality of the food.
Importance of Packaging Materials
Freeze dried meals packaged in airtight, moisture-resistant containers can last up to 25 years or more when stored properly. Materials like Mylar or foil laminates are ideal for this purpose, as they prevent moisture and oxygen from entering the package. When shopping for freeze dried meals, look for packaging that meets US military standards for shelf life, such as the MRE (Meal, Ready-to-Eat) packaging.
Packaging Considerations for Long-Term Storage
For long-term storage, it’s essential to consider the packaging’s ability to maintain airtight seals and withstand various environmental conditions. Consider the thickness and quality of the packaging materials, as well as the presence of any desiccants or oxygen absorbers to control humidity and prevent spoilage. For example, the US military’s MRE packaging includes an oxygen absorber to extend shelf life.
Best Practices for Packaging Freeze Dried Meals
When storing freeze dried meals, it’s essential to maintain a consistent storage temperature between 50-70°F (10-21°C) and humidity levels below 60%. Avoid storing packages near direct sunlight, heat sources, or moisture-prone areas. Regularly inspect the packaging for signs of damage or deterioration, and replace any compromised packages to maintain the overall shelf life of the stored meals.
