Understanding Mylar Bags
Have you ever reached into your pantry, only to find that the bag of rice you thought would last for months is now infested with pantry moths, or that your emergency supply of beans is now rock hard and inedible? In a world where food security is increasingly important, proper food storage is paramount. That’s where food storage mylar bags come into play. These unassuming pouches are a powerful tool in extending the shelf life of your essential supplies.
Mylar bags, when used correctly with oxygen absorbers, offer a superior solution for long-term food storage, protecting food from moisture, oxygen, light, and pests, thereby extending its shelf life. This guide will explore everything you need to know about using food storage mylar bags effectively.
Mylar bags aren’t your ordinary plastic storage bags. They’re engineered for a specific purpose: to create an impermeable barrier around your food. The heart of a mylar bag is its construction. Typically, mylar is composed of a polyester film, often laminated with a thin layer of aluminum. This combination results in a material that’s remarkably strong, flexible, and most importantly, impermeable to gases, light, and moisture.
The thickness of mylar bags is measured in mils (thousandths of an inch). Thicker bags offer greater protection and are generally preferred for long-term storage. You’ll find various sizes available, from small pouches suitable for single servings to large bags designed to hold several pounds of food.
The effectiveness of food storage mylar bags stems from their ability to block the elements that cause food to deteriorate. Think of them as a vault for your food, keeping out the culprits that lead to spoilage.
Why Mylar Bags are Your Food’s Best Friend
Mylar bags offer a range of benefits, each contributing to the increased longevity and preservation of your food supplies.
Oxygen Barrier
Oxygen is a major enemy of food preservation. It causes oxidation, leading to rancidity in fats and oils, discoloration, and a general degradation of flavor and nutritional value. Food storage mylar bags are designed to be virtually impermeable to oxygen, creating an environment where these destructive processes are significantly slowed down.
Moisture Protection
Moisture is another major cause of spoilage, leading to mold growth, clumping, and a loss of texture. Mylar bags act as a robust moisture barrier, preventing water vapor from reaching your food and compromising its quality.
Light Shield
Light, particularly ultraviolet (UV) light, can degrade vitamins, alter flavors, and cause other undesirable changes in food. Food storage mylar bags, especially those with an aluminum layer, block light effectively, preserving the nutritional content and taste of your stored food.
Pest Prevention
Pantry pests like weevils, moths, and rodents can wreak havoc on your food supplies. Mylar bags create a physical barrier that these pests can’t easily penetrate, protecting your food from infestation.
Extended Shelf Life
By mitigating the effects of oxygen, moisture, light, and pests, food storage mylar bags can dramatically extend the shelf life of many foods. Grains, beans, rice, dried fruits, and other dry goods can potentially last for decades when properly stored in mylar bags with oxygen absorbers.
The Art of Using Mylar Bags for Food Storage
Using food storage mylar bags effectively involves a few key steps. Follow this guide to maximize your food preservation efforts:
Gather Your Supplies: You’ll need food storage mylar bags of the appropriate size and thickness, oxygen absorbers (calculate the correct amount based on bag size), a heat sealer (an iron or impulse sealer will work), and the food you intend to store. Ensure your food is properly dried and prepared. Desiccant packs can be added for foods with very low moisture content.
Prepare the Food: The food must be dry. Even small amounts of moisture can promote mold growth, even in a mylar bag. Dehydrate fruits and vegetables thoroughly, and ensure grains and beans are completely dry.
Fill the Bags: Place the prepared food into the food storage mylar bag, leaving some space at the top for sealing.
Add Oxygen Absorbers: Oxygen absorbers are crucial. They remove any remaining oxygen from the bag, creating an oxygen-free environment that inhibits spoilage. Place the correct number of oxygen absorbers into the bag.
Remove Excess Air: Gently press down on the bag to expel as much air as possible.
Heat Seal the Bag: Use a heat sealer to create a tight, airtight seal across the top of the bag. A proper seal is essential to prevent oxygen and moisture from entering.
Label and Date: Clearly label the bag with the contents and the date it was sealed. This will help you track your inventory and ensure you use the oldest food first.
Store Properly: Store the sealed food storage mylar bags in a cool, dark, and dry place. A pantry, basement, or storage closet are all suitable options.
Choosing the Right Food Storage Mylar Bags
Selecting the appropriate food storage mylar bags is essential for optimal results. Consider these factors:
Thickness Matters
The thickness of the bag determines its durability and its ability to block oxygen and moisture. Thicker bags (five mils or more) are generally recommended for long-term storage, while thinner bags may be suitable for shorter periods.
Size Considerations
Choose a bag size that closely matches the volume of food you’re storing. This minimizes the amount of air trapped inside, reducing the workload for the oxygen absorbers.
Quality is Key
Opt for food-grade food storage mylar bags from reputable suppliers. These bags are specifically designed for food storage and are free from harmful chemicals.
Oxygen Absorbers: Your Silent Food Savers
Oxygen absorbers are small packets containing iron powder that reacts with oxygen to remove it from the sealed environment. They are a vital component of food storage mylar bag storage.
To use oxygen absorbers effectively:
Calculate the Size: Use the correct number of oxygen absorbers based on the size of the bag and the amount of food being stored. Overestimate rather than underestimate.
Handle with Care: Oxygen absorbers begin working as soon as they are exposed to air. Keep them sealed until you are ready to use them.
Test for Functionality: Before using oxygen absorbers, check that they are still working. They should feel soft and pliable. If they are hard or brick-like, they have already been exposed to too much air and should not be used.
What Foods Thrive in Mylar Bags
Food storage mylar bags are ideal for storing a wide range of dry foods, including:
Grains: Rice, wheat, corn, oats, barley
Legumes: Beans, lentils, peas
Dried Fruits and Vegetables: Apples, bananas, carrots, onions
Pasta: Macaroni, spaghetti, noodles
Powdered Milk: Whole milk, nonfat dry milk
Other Dry Goods: Sugar, salt, spices
Foods with high moisture or oil content are not suitable for food storage mylar bag storage, as they can spoil even in the absence of oxygen.
Avoidable Mylar Bag Mistakes
Even with the best intentions, mistakes can happen. Avoid these common pitfalls:
Using Under-Thickness Bags: Skimping on bag thickness can compromise the barrier against oxygen and moisture.
Insufficient Oxygen Absorption: Not using enough oxygen absorbers can leave residual oxygen in the bag, leading to spoilage.
Faulty Sealing: A poor heat seal allows oxygen and moisture to enter the bag.
Sunlight and Heat Exposure: Storing bags in direct sunlight or high temperatures accelerates spoilage.
Moisture Content Foods: Storing foods with high moisture content promotes mold growth.
Long-Term Storage: The Big Picture
For truly long-term food storage, consider these factors:
Environmental Control: Maintain a cool, dark, and dry storage environment.
Pest Prevention: Protect bags from pests by storing them in airtight containers or on shelves.
Regular Inspections: Check the integrity of the bags periodically for signs of damage or leakage.
Shelf Life: Be realistic about shelf life expectations. While some foods can last for decades, others may degrade over time.
Mylar Bags Compared to Alternatives
Mylar bags are just one option for food storage. Here’s how they stack up against other methods:
Plastic Containers: Plastic containers are suitable for short-term storage but are not impermeable to oxygen and moisture.
Vacuum Sealing: Vacuum sealing removes air but doesn’t address the oxygen that’s trapped within the food itself.
Canning: Canning is a great option for wet foods but requires specialized equipment and can alter the texture and flavor of the food.
Mylar bags excel at long-term storage of dry goods, offering a balance of effectiveness, cost-effectiveness, and ease of use.
