Why Proper Storage Matters for Freeze Dried Food
Before we get into the how-tos of storing freeze dried food, it’s essential to understand why proper storage is so critical. The secret to the long shelf life of freeze-dried food is the process itself. Freeze-drying, also known as lyophilization, involves freezing the food and then reducing the surrounding pressure to allow the frozen water in the food to sublimate directly from the solid phase to the gas phase, skipping the liquid phase entirely. This process removes nearly all the moisture, leaving behind a product that is incredibly stable and resistant to spoilage.
However, even the smallest amount of moisture, exposure to oxygen, light, inconsistent temperature, or attack from pests can compromise the quality and shelf life of your freeze-dried goodies. Let’s explore those in a bit more depth.
The Moisture Menace
Moisture is the ultimate enemy of storing freeze dried food. Freeze-drying removes almost all moisture, creating a product that resists spoilage. However, if moisture seeps back in, it can rehydrate the food, leading to bacterial growth, mold, and a whole host of undesirable consequences. Your freeze-dried delicacies may clump together, lose their texture, and, worst of all, spoil, rendering them inedible. A damp environment makes storing freeze dried food a risky endeavor, and you could end up with a sad, spoiled mess instead of long-lasting nourishment. This is why the type of container matters immensely.
Oxygen’s Oxidative Assault
Oxygen, while essential for life, can wreak havoc on stored freeze dried food. It causes oxidation, a chemical process that leads to rancidity, off-flavors, and a loss of essential nutrients. Foods high in fats are particularly susceptible to oxidation. Storing freeze dried food properly requires oxygen-limiting barriers to maintain its quality. When oxygen finds its way into your freeze dried food storage, taste and nutritional value degrade over time.
Light’s Damaging Rays
Light, especially ultraviolet (UV) light, can degrade the color, flavor, and nutritional value of freeze dried food. Light can break down vitamins and other sensitive compounds, diminishing the overall quality. Exposure to light is a common problem when storing freeze dried food and a simple opaque container can prevent this. By blocking out the light, you keep your freeze dried food as vibrant and nutritious as when you first stored it.
Temperature’s Treacherous Fluctuations
Consistent, cool temperatures are crucial for optimal freeze dried food storage. Large temperature swings can cause condensation inside containers, introducing moisture and accelerating spoilage. Fluctuating conditions can wreak havoc on your attempts at storing freeze dried food.
Pests’ Perilous Presence
Insects and rodents are always on the lookout for a free meal. They can chew through packaging, contaminate food, and introduce bacteria. Storing freeze dried food without adequate protection from pests can lead to costly losses and potential health risks.
The Best Containers for Storing Freeze Dried Food
Choosing the right container is paramount for successful storage of freeze dried food. Several options offer varying degrees of protection, each with its own advantages and disadvantages.
The Mylar Marvel
Mylar bags are the gold standard for long-term storage of freeze dried food. They are made of a laminated material that provides an excellent barrier against moisture, oxygen, and light. When storing freeze dried food, mylar bags offer unmatched protection due to their density and protective layers. Thickness matters; opt for thicker mylar bags (four point five mil or higher) for superior protection. Properly heat-sealing the bags is crucial. Use a heat sealer to create an airtight seal, ensuring no air or moisture can penetrate. Before sealing, add oxygen absorbers to remove any remaining oxygen inside the bag. Make sure to use the appropriate size of oxygen absorber based on the volume of the bag. Store unused oxygen absorbers in an airtight container to prevent them from becoming saturated.
Buckets of Bulk
Food-grade buckets with gamma seal lids are excellent for storing freeze dried food in bulk. Buckets offer a robust and stackable storage solution, making them ideal for larger quantities. Always use food-grade buckets to prevent harmful chemicals from leaching into your food. Gamma seal lids create an airtight seal, preventing moisture and pests from entering. For added protection, line the bucket with a mylar bag before filling it with freeze dried food. When storing freeze dried food in buckets, a mylar liner offers that extra barrier that takes your storage plan from good to excellent.
Glass Jars: Proceed with Caution
Glass jars, while reusable and aesthetically pleasing, have limitations when it comes to storing freeze dried food. They are not oxygen-proof and are susceptible to light damage. Glass is also bulky, meaning storing freeze dried food in this manner is more difficult than mylar bags. However, glass jars can be suitable for short-term storage or pantry display, provided you protect them from light. Keep them in a dark pantry or cover them with opaque materials to minimize light exposure.
Vacuum-Sealed Ventures
Vacuum-sealed bags can be used for storing freeze dried food, but they have their limitations. While they remove air, they are not as airtight as mylar bags over the long term. Vacuum sealing can also crush fragile foods. Avoid using vacuum-sealed bags for oily foods, as the vacuum pressure can draw out the oils and cause the bag to deteriorate. Despite their convenience, these bags are generally best suited for shorter durations.
Preparing Freeze Dried Food for Storage
Proper preparation is just as crucial as choosing the right container when storing freeze dried food. Following these steps will ensure your food is ready for long-term storage.
Cooling is Key
Always allow freeze dried food to cool completely before packaging it. Warm food can create condensation inside the container, introducing moisture and promoting spoilage.
Packaging Perfection
Fill containers to the appropriate level, leaving some headspace. Remove as much air as possible, especially when using mylar bags. Double-seal bags to ensure an airtight closure, and check for any leaks before storing.
Labeling is Law
Clearly label each container with the date, contents, and any other relevant information, such as the “best by” date. This helps you keep track of what you have and when you need to use it.
Ideal Storage Conditions
Where you store your freeze dried food is just as important as how you store it. Maintaining the right environmental conditions will maximize its shelf life.
Temperature Tenacity
Aim for a consistent temperature range of sixty to seventy degrees Fahrenheit (fifteen to twenty-one degrees Celsius). Higher temperatures can significantly reduce the shelf life of freeze dried food.
Light’s Lethal Impact
Store your freeze dried food in a dark location, away from direct sunlight. Pantries, basements, and closets are ideal. If you must store containers in a lighted area, cover them with opaque materials.
Humidity’s Harmful Hug
Keep freeze dried food in a dry location. Avoid damp basements or areas prone to humidity. Consider using desiccants, such as silica gel packets, to absorb any excess moisture.
Pest Prevention
Store containers off the floor to prevent pests from reaching them. Seal all containers tightly to prevent infestations, and conduct regular inspections for any signs of pests.
Determining Shelf Life and Monitoring Food Quality
While freeze dried food has a long shelf life, it’s essential to understand how to determine its quality and when to discard it.
Dates Decoded
Understand the difference between “best by” and “expiration” dates. “Best by” dates indicate when the food is at its peak quality, while “expiration” dates suggest when the food may no longer be safe to consume. Freeze dried food is often safe to eat long past the “best by” date, provided it has been stored properly.
Factors in Shelf Life
The shelf life of freeze dried food depends on various factors, including the type of food, storage conditions, and packaging quality. Some foods, such as fruits and vegetables, may have a longer shelf life than others.
Spotting Spoilage
Regularly inspect your freeze dried food for any signs of spoilage. Look for visual cues such as mold or discoloration, and smell for any off-odors. If the texture has changed or the food appears to be compromised in any way, it’s best to discard it.
Tips for Specific Types of Freeze Dried Food
Different types of freeze dried food may require slightly different storage considerations.
Fruits and Vegetables
Be mindful of the moisture and sugar content of freeze dried fruits and vegetables. Store them in airtight containers with oxygen absorbers to prevent spoilage.
Meats
Ensure freeze dried meats have a low fat content and have been handled properly before freeze-drying. Store them in mylar bags with oxygen absorbers to prevent rancidity.
Dairy
Freeze dried dairy products are susceptible to fat oxidation. Store them in opaque containers with oxygen absorbers to minimize exposure to light and oxygen.
Meals
When storing freeze dried meals with mixed ingredients, ensure all components are properly dried and packaged separately if necessary. This prevents moisture transfer and ensures the longevity of the entire meal.
