Step 3: Sealing Containers Properly for Freshness
Sealing freeze dried foods is the critical barrier between your preserved items and potential contamination. Proper sealing determines the longevity and quality of your stored foods, making this step absolutely essential in the preservation process. The goal is to create an airtight environment that locks out moisture, oxygen, and potential contaminants.
Vacuum sealing offers the most reliable method for protecting freeze dried foods. Invest in a quality vacuum sealer designed specifically for food storage. When using this technique, carefully place your freeze dried foods into vacuum-seal bags, leaving enough space at the top for a proper seal. Run your fingers along the bag’s edge to ensure no food particles interfere with the sealing process. Compress the bag gently to remove as much air as possible before final sealing.
For those using glass jars or plastic containers, the sealing process requires equal precision. Inspect the container’s rim carefully, checking for any chips, cracks, or imperfections that might compromise the seal. Wipe the rim clean with a dry, lint-free cloth to remove any food particles or moisture. If using oxygen absorbers, place them carefully inside the container before sealing. These small packets work wonders in removing residual oxygen that could degrade your freeze dried foods.
Tight-fitting lids are your best defense against moisture and air infiltration. Apply gentle pressure when closing containers, listening for the subtle click that indicates a complete seal. For mason jars, ensure the rubber gasket is clean and intact. Pro tip: Gently tap the lid after sealing to check for any potential air pockets or incomplete seals. A properly sealed container should feel firm and show no signs of give when pressed.
For long-term storage, consider double-protection methods. After initial sealing, you can add an extra layer of protection by placing sealed containers in mylar bags with additional oxygen absorbers. This multi-layered approach provides maximum defense against environmental factors that could compromise your freeze dried foods.
Always label your containers with the date of sealing and contents. This simple step helps you track storage time and rotate your stock effectively. According to Penn State Extension, proper sealing can extend the shelf life of freeze dried foods significantly, turning your preservation efforts into a long-lasting food storage solution.
Step 4: Label Containers with Dates and Contents
Labeling is the unsung hero of effective food storage, transforming your freeze dried food preservation from a guessing game to a precise system.
