How to Properly Seal Opened Freeze Dried Meal Packages?

Choosing Sealing Methods

When sealing opened freeze-dried meal packages, consider the available options and their effectiveness. A food-grade vacuum sealer is the most reliable method, as it removes air from the package, preventing moisture and other contaminants from entering. However, if a vacuum sealer is not available, aluminum foil or airtight plastic bags can be used as alternatives. To seal with aluminum foil, wrap the package tightly and press the foil onto the edges to create an airtight seal. For airtight plastic bags, use a double-ziplock technique, sealing the package with two layers of plastic bags.

Additional Techniques for Long-Term Storage

To ensure the quality and safety of the freeze-dried meal, additional techniques should be employed for long-term storage. First, store the sealed package in an airtight container to prevent external moisture from entering. Next, label the package with the date and contents, and store it in a cool, dark place, such as a pantry or cupboard. Avoid storing the package in direct sunlight, near heat sources, or in humid environments. For optimal shelf life, store the sealed package at temperatures below 70°F (21°C) for up to 25 years. When planning to consume the meal, inspect the package for signs of degradation, such as moisture, pests, or mold, before consuming the meal.
