Are you tired of throwing away food that spoils too quickly? Do you dream of a well-stocked pantry, ready to weather any storm or simply provide nutritious meals for your family? Perhaps you’re just looking for ways to reduce food waste and save money. Whatever your motivation, the answer might be simpler than you think: food storage in mylar bags. Properly using mylar bags is a powerful method of safeguarding your food supply and extending its shelf life significantly. Mylar bags, when used correctly, offer a superior method for long-term food storage, protecting food from oxygen, moisture, light, and pests, leading to a longer shelf life and peace of mind.
Understanding Mylar Bags: The Foundation of Long-Term Food Preservation
To effectively utilize mylar bags for food storage, it’s essential to understand what they are and why they work so well.
Delving into the Composition of Mylar
Mylar, often mistakenly referred to as a type of plastic, is actually a brand name for a specific type of polyester film, technically known as biaxially-oriented polyethylene terephthalate (PET). However, the term “mylar” has become a generic term for similar films used in various applications, including food storage. The key to mylar’s exceptional performance as a food storage solution lies in its unique properties. It’s incredibly strong, resistant to punctures and tears, and most importantly, it provides an excellent barrier against oxygen, moisture, and light. This barrier is significantly enhanced by a thin layer of aluminum that is often laminated to the PET film. This aluminum layer creates a virtually impermeable shield, preventing the degradation of food caused by exposure to these elements.
Exploring the Different Types of Mylar Bags
Not all mylar bags are created equal. When selecting mylar bags for food storage, consider these key factors:
Thickness: Mylar bag thickness is measured in mils (thousandths of an inch). Thicker bags (typically five mils or greater) provide superior protection and are recommended for long-term storage. Thinner bags may be suitable for shorter-term needs.
Sizes and Shapes: Mylar bags come in a wide variety of sizes, from small pouches perfect for individual servings to large bags capable of holding several pounds of food. Choose the size that best suits your storage needs and the quantity of food you plan to store.
Food-Grade Material: This is absolutely crucial. Always ensure that the mylar bags you purchase are specifically labeled as “food-grade.” This designation means the bags have been manufactured using materials that are safe for contact with food and will not leach harmful chemicals into your stored provisions.
Clear vs Opaque: While clear mylar bags exist, opaque (usually silver or black) mylar bags are generally preferred for long-term food storage because they provide superior protection against light, which can degrade food quality over time.
Why Mylar Bags Outperform Other Storage Methods
Mylar bags offer a significant advantage over common storage methods like plastic containers or resealable bags. While these options may be adequate for short-term storage, they lack the crucial barrier properties of mylar. Plastic containers, even those labeled as airtight, are often permeable to oxygen and moisture. Resealable bags, like those made by Ziploc, offer even less protection.
The superior oxygen and moisture barrier of mylar bags prevents oxidation, which can cause food to become stale, rancid, or lose its nutritional value. The light protection offered by opaque mylar bags further preserves the quality of the food by preventing light-induced degradation. Moreover, mylar bags are much more resistant to pests than other storage options. Their robust construction makes it difficult for rodents and insects to penetrate, safeguarding your food supply from contamination and spoilage.
Preparing Food for Storage: Laying the Groundwork for Success
Proper preparation is just as important as choosing the right mylar bags. This includes carefully selecting the right foods for long-term storage, making sure it is cool, and thoroughly clean.
Choosing the Right Foods for Long-Term Preservation
Mylar bags are best suited for storing dry goods with a low moisture content. Excellent candidates include:
Grains: Rice, wheat, corn, oats, barley
Legumes: Beans, lentils, peas
Pasta: Dried pasta varieties
Dehydrated Fruits and Vegetables: Apples, bananas, carrots, onions
Seeds and Nuts: (Note: Nuts have a higher oil content and may not store as long as other items).
Foods with high moisture content, such as fresh fruits and vegetables, should not be stored directly in mylar bags unless they have been properly dehydrated first. The moisture in these foods can promote the growth of mold and bacteria, leading to spoilage.
Dehydration: Removing Moisture for Enhanced Longevity
Dehydration is the process of removing moisture from food, thereby inhibiting the growth of microorganisms and enzymes that cause spoilage. Properly dehydrated foods can last for years when stored in mylar bags with oxygen absorbers. You can dehydrate food using an oven or a dedicated food dehydrator. Ensure that the food is dried to the recommended moisture content levels for long-term storage. These levels vary depending on the type of food. A general guideline is that the food should be brittle or snap easily when bent.
The Importance of Cooling Food Completely
Before sealing food in mylar bags, it’s essential to allow it to cool completely. Warm food can create condensation inside the bag, which can lead to moisture buildup and spoilage. Allow dehydrated food to cool to room temperature before packaging.
Cleaning is Paramount
Carefully inspect and clean all food items before packing them in mylar bags. Remove any dirt, debris, or signs of spoilage. This will help prevent contamination and ensure the longevity of your stored food.
Mastering the Packing Process: A Step-by-Step Guide
The packing process is a critical step in successful food storage in mylar bags. Follow these steps carefully:
Gathering Your Essential Supplies
Before you begin, gather the following supplies:
Mylar bags (appropriate size and thickness for your needs)
Oxygen absorbers (calculate the correct amount)
Heat sealer (a reliable heat sealer is crucial for creating an airtight seal)
Marker or labels (for clear identification of stored food)
Measuring cups/scoops (for accurate portioning)
Calculating Your Oxygen Absorber Needs
Oxygen absorbers are small packets containing iron powder that absorb oxygen from the sealed mylar bag. This creates an oxygen-depleted environment, which inhibits the growth of microorganisms and prevents oxidation. The correct amount of oxygen absorbers depends on the size of the bag and the type of food being stored. Generally, a three hundred cc oxygen absorber is sufficient for a one-gallon mylar bag filled with dry goods. Consult a reliable resource for specific recommendations based on your needs.
Filling the Mylar Bags with Care
Fill the mylar bags with the prepared food, leaving some headspace at the top (typically one to two inches). Avoid overfilling the bags, as this can make it difficult to create a proper seal.
Adding Oxygen Absorbers Promptly
Once the bags are filled, quickly add the appropriate number of oxygen absorbers. Oxygen absorbers begin working as soon as they are exposed to air, so it’s essential to add them quickly and seal the bags immediately.
Heat Sealing: Creating an Airtight Barrier
Use a heat sealer to create a strong, airtight seal across the top of the mylar bag. A double seal is highly recommended for added protection. Test the seal by gently pressing on the bag to ensure no air escapes. If the seal is weak, reseal it immediately.
Labeling and Dating for Easy Identification
Clearly label each mylar bag with the name of the food, the date of packaging, and a “best by” date. This will help you keep track of your stored food and ensure that you use it before it expires.
Storage Essentials: Maintaining the Integrity of Your Stored Food
Proper storage is essential for maintaining the quality and longevity of your stored food.
Optimal Storage Conditions: The Key to Long-Term Preservation
Store mylar bags in a cool, dark, and dry environment. The ideal temperature range is between forty and seventy degrees Fahrenheit. Protect the bags from pests, such as rodents and insects, by storing them in sealed containers or bins.
Choosing the Right Storage Location
Suitable storage locations include basements (if they are dry and free from moisture), pantries, and under beds. Avoid storing mylar bags in damp or humid areas, as this can compromise their integrity.
Protecting from Physical Damage: Ensuring Bag Integrity
Protect mylar bags from physical damage by storing them in containers or bins that prevent punctures or tears. Handle the bags carefully to avoid damaging the seals.
Regular Monitoring: Keeping a Watchful Eye
Regularly inspect your stored food to ensure that the mylar bags are still intact and that there are no signs of spoilage.
Consistent Inspections: Catching Problems Early
Periodically inspect the mylar bags for punctures, tears, or any signs of damage. Look for any signs of spoilage, such as mold growth or off odors.
Testing the Seal Integrity: Ensuring Airtight Protection
Visually inspect the seals to ensure they are intact and airtight. You can also perform a “squeeze test” by gently squeezing the bag to see if any air escapes.
Proper Disposal: Removing Compromised Bags
Dispose of any damaged or spoiled bags properly to prevent contamination of other stored food.
Rotating Your Stock: First In, First Out
Use the First In, First Out (FIFO) method to ensure that you use your oldest stored food first. This will help prevent food from expiring and ensure that you always have a fresh supply on hand.
Navigating Potential Challenges: Troubleshooting Common Issues
Even with careful preparation and storage, you may encounter some common issues. Here’s how to troubleshoot them:
Bag Inflation: Possible Causes and Solutions
If your mylar bags inflate after sealing, it could be due to several reasons: excess moisture in the food, inadequate sealing, or continued gas production from the food. Ensure that your food is properly dried and that you create a strong, airtight seal.
Oxygen Absorbers Not Working: Troubleshooting Tips
If your oxygen absorbers don’t seem to be working, it could be because they were exposed to air for too long before sealing, you used the incorrect amount, or they were expired. Use fresh oxygen absorbers and seal the bags immediately after adding them.
Food Spoilage: Identifying and Addressing Causes
Food spoilage can occur due to improper dehydration, inadequate sealing, or incorrect storage. Ensure that your food is properly prepared and stored in a cool, dark, and dry environment.
Safety First: Important Considerations for Storing Food in Mylar Bags
While food storage in mylar bags is generally safe, it’s important to be aware of potential risks and take precautions.
Botulism Risk: Understanding the Minimal Threat
Botulism is a rare but serious illness that can result from consuming improperly stored food. The risk of botulism is very low when storing properly dehydrated dry goods in mylar bags with oxygen absorbers. Oxygen absorbers remove the oxygen that botulism bacteria need to thrive.
Allergies: The Importance of Clear Labeling
If you have any allergies, it’s essential to clearly label your mylar bags with all ingredient information. This will help you avoid accidentally consuming foods that you are allergic to.
Embrace Food Safety: A Foundation for Safe Storage
It is essential to follow all food safety guidelines when storing food in mylar bags. This includes washing your hands thoroughly before handling food and storing food at the proper temperature.
