Oxygen absorbers emerge as silent heroes in the battle against degradation, safeguarding your edibles for extended periods. But wielding these protectors isn’t just a case of dropping them into your Gran’s pickling jar; it’s an understanding of chemistry, preparation, and precision. Whether you’re a prepper, a homesteader, or a DIY storage enthusiast, mastering the use of oxygen absorbers can be the difference between savoring or wasting your carefully stored food. Let’s delve into the steps that will empower you to use these little packets of preservation effectively and confidently. We’ll explore why they are indispensable, the potential pitfalls, and the exact practices that will elevate your food storage game.
How to Use Oxygen Absorbers for Food Storage
Step 1: Gather Your Arsenal
To begin this culinary conservation journey, you’ll need a set of tools. Oxygen absorbers are key components, but they’re best employed alongside the following items:
Food-Grade Storage Containers: These should be clean and dry to create the best storage environment. Mylar bags, glass canning jars, or specifically designed airtight food storage containers are ideal choices.
Sealing Equipment: For a vacuum seal, there’s nothing quite like a vacuum sealer. For heat seals, use a simple household iron or an actual heat sealing machine.
Storage Supplies: From desiccants to labels, to ensure you’re fully prepped for food storage, ensure you have everything you need.
Ensure that every item is food-grade and thoroughly sanitized. The last thing you want to find upon opening your long-term storage is a batch tainted by non-food-safe plastic odors.
Step 2: Prepare Your Comestibles’ New Home
Sterilize your containers before use. For glass or heat-sealable plastics, this means a good wash with hot soapy water and then a rinse with diluted bleach. For mylar bags, follow the same sterile washing, then make sure any excess moisture is removed before employing heat seals to close them. It’s important to note that for different types of food with varying oil or moisture content, different containers may be best:
Dry foods with low oil/moisture content: Canning jars or mylar bags provide the perfect protective environment against degradation and pests.
Foods with higher oil/moisture content: Plastic buckets or metal cans can be your airtight answer.
By selecting the correct container, you’re already enhancing your chances of successful long-term food storage.
Step 3: The Perfect You: Quantity of Quality Absorbers
Calculating the right number of oxygen absorbers isn’t a guessing game; it’s a science. Typically, 300-500 cubic centimeters (cc) of air is within 1 quart of space, so you’d need an absorber that can handle all the oxygen. Here’s a general guideline:
For quart-sized containers, one 100cc absorber will suffice.
For gallon-sized containers, you might need three to four 300cc absorbers.
It’s important not to skimp, as too many absorbers can create a near-vacuum in your storage vessel, ultimately squishing your precious provisions.
Step 4: Welcome in the Absorbers
With your quantities sorted, the placement of the absorbers is next. It’s all too easy to spoil the broth with the placement of too many absorbers. Distribute them evenly to remove the risk of any corner of your container becoming an oxygen-rich zone.
Use the largest absorbers that will fit comfortably.
For powders, you can place the absorber atop the food, while for larger items, placing it against the side of the container can work well.
Step 5: Fortify the Seal
An airtight seal is not just a “nice to have”; it’s the barrier that will keep oxygen, and with it, decay, from your stores. For glass jars and cans, this means checking the seal integrity. For mylar bags or any other plastic containers, repeatedly ensure the heat seal is perfect, using the iron or sealer on a high setting.
It’s good practice to inspect for leaks or punctures each time before using an oxygen-less store of food. Remember, a sealed container doesn’t necessarily mean an airtight one.
Step 6: The Royal Storage
How you store your now-O2-less edibles is as crucial as the steps before. Proper temperature and humidity are the basics, but also consider:
Temperature: Store in a cool, dry place, away from light. Avoiding temperature extremes will maintain the efficacy of your absorbers and the integrity of the stored food.
Humidity: Dry foods require fairly low humidity; if you’re using desiccants, they can help here. Moist or wet foods should maintain a humidity near 15% – 20% for optimal storage.
Step 7: Guardian Inspections
Oxygen absorbers have a shelf-life, too, typically about a year once they’re exposed to air. Monitor and replace them as necessary. Regularly inspect for condensation or any signs that the seal or storage may have been compromised. Remember, when one pack’s power has passed, its power to protect will have passed as well.
How Do Oxygen Absorbers Work
Oxygen absorbers function by a scientific principle known as oxidation-reduction (redox) reaction. These little powerhouses contain a small amount of iron powder that, when exposed to oxygen in the air, reacts and forms iron oxide, commonly known as rust. This chemical process effectively ‘eats up’ the oxygen molecules within the sealed environment. As the available oxygen is sharply reduced, the potential for oxidative spoilage and the growth of aerobic pathogens is also greatly minimized.
In essence, oxygen absorbers serve to maintain an anaerobic condition that safeguards the quality and flavor of your stored food. It’s a deceptively simple yet crucial addition to any serious long-term food preservation strategy.
Recommended Containers for Storing Your Food
When it comes to choosing the ultimate guardians for your gastronomic goods, the selection of containers is paramount. Here are the contenders that merit consideration:
Glass Jars: A classic choice for a reason—they’re impermeable and non-reactive, keeping flavors and nutrients locked in, and odors and moisture locked out.
Mylar Bags: Lightweight champions of freshness, these bags offer excellent barrier properties and resistance to punctures, perfect for on-the-go food storage solutions.
Food-Grade Buckets: These stalwarts provide the bulk defense against the elements and are ideal for sizable storage of dry goods.
Vacuum Sealed Bags: The ultimate in food-saver technologies, pulling tight against your foods to help prevent freezer burn and extend shelf life.
Metal Cans: When a fortress of solitude is needed, metal cans withstand the ravages of time and severe environmental conditions.
Balance is key. Taking into consideration your food’s characteristics and storage location will drive your choice towards the optimal container, ensuring your edibles emerge as fresh as they entered, irrespective of the epochs they endure.
