What’s the best method for food storage: mylar, vacuum seal, or canning?

Engaging Introduction: Why is Proper Food Storage Important.

How do you usually store your food. Do you just toss it in the fridge or pantry and forget about it. Or do you take the time to carefully package it for maximum shelf life. If you’re like most people, you probably fall somewhere in between. But with the rise in food prices and the growing interest in long-term food storage for emergency preparedness, more and more people are looking for the best methods to store their food and keep it fresh for as long as possible. In this article, we’re going to dive into three popular methods: mylar bags, vacuum sealing, and canning.

Mylar Bags for Food Storage

So, what are mylar bags.

Mylar bags are a type of food storage bag made from a special type of polyester resin. The bags are known for their strength, flexibility, and resistance to moisture and light, making them an excellent choice for long-term food storage.

How does food storage work with mylar bags.

Storing food in mylar bags usually involves placing the food items in the bag, adding an oxygen absorber, and then sealing the bag with a heat sealant. This process creates an oxygen-free environment inside the bag, which greatly extends the shelf life of the food stored inside.

What are the pros and cons of using mylar bags for food storage.

Mylar bags are favored for their longevity. According to the Utah State University Extension Service, food stored in mylar bags can last up to 30 years if properly sealed and stored in a cool, dry place. The bags are also lightweight and easy to store, making them a popular choice for hikers and emergency preppers.

However, mylar bags aren’t without their downsides. They can be punctured or torn if not handled with care, and they require a heat sealer to ensure a good seal. Furthermore, once a mylar bag is opened, you can’t reseal it, which can lead to waste if you’re not able to consume all the food at once.

Vacuum Sealing as a Food Storage Method

What is vacuum sealing.

Vacuum sealing is a method of packaging that removes air from the package prior to sealing. This creates an airtight environment that can significantly extend the shelf life of food by preventing the growth of bacteria or fungi.

How does food storage work with vacuum sealing.

The process of vacuum sealing is relatively simple: place your food in a vacuum sealer bag, insert the open end of the bag into the vacuum sealer, and press the button to start the sealing process. The machine removes the air and seals the bag, creating an airtight environment.

What are the advantages and disadvantages of vacuum sealing.

Vacuum sealing is known to preserve the freshness and flavor of foods, particularly meats and vegetables, for longer periods. Studies have shown that vacuum-sealed food can last 3-5 times longer than food stored in plastic bags or containers.

However, vacuum-sealed bags are not as durable as mylar bags and can be punctured or torn more easily. Additionally, vacuum sealing machines can be expensive, and the bags are generally more costly than other food storage options.

As we delve deeper, we’ll discover more about canning, the third method of food storage. Its history, process, and the pros and cons it offers in comparison to mylar bags and vacuum sealing. Stay tuned for an enlightening exploration of food storage techniques.

Canning for Food Storage

Canning is the grandparent of modern food storage—tried, tested, and trusted for generations. If you grew up watching a family member line up jars of peaches, green beans, or tomatoes on the pantry shelves, you’ve seen canning in action. But what exactly is it, and why does it continue to hold its ground alongside mylar bags and vacuum sealing.

What is canning, and how does it work.

Canning is the process of preserving food in glass jars by heating it to a temperature that destroys microorganisms and inactivates enzymes. The heated jars are sealed, creating a vacuum that prevents new bacteria from spoiling the food. There are two main types of canning: water bath canning (for high-acid foods like jams, jellies, and pickles) and pressure canning (for low-acid foods like vegetables, meats, and soups).

Advantages and disadvantages of canning

The biggest benefit of canning is that it’s a time-tested method for making shelf-stable foods that can last for years (we’ll look at the numbers soon. It’s also incredibly versatile; you can can everything from fruits and veggies to meats and prepared meals. Plus, home canning lets you control the ingredients—no preservatives, just real food.

But canning has its challenges. The process is more time-consuming and requires specialized equipment, like a canner and glass jars. There’s a learning curve to ensure food safety—botulism is a real concern if you don’t follow guidelines carefully. And unlike mylar or vacuum sealing, canning jars are heavy, breakable, and take up more space in storage.

Comparing Mylar, Vacuum Sealing, and Canning

Now that we’ve introduced all three methods, how do they stack up against each other. Let’s break it down across a few key categories: cost, ease of use, and shelf life.

Cost

  • Mylar Bags: Initial costs include the bags, oxygen absorbers, and a heat sealer—often around $40-100 for a starter setup, with ongoing costs for bags and absorbers.
  • Vacuum Sealing: Machines can range from $40 to $200+ depending on features. Replacement bags are pricier than regular plastic bags, though the investment can pay off if you store a lot of food.
  • Canning: Upfront costs are a bit higher. You’ll need a canner (about $70-$150 for pressure canners), jars, and lids. Jars are reusable, but lids generally aren’t.

Ease of Use

  • Mylar: Fairly simple once you get the hang of heat sealing, though not resealable after opening.
  • Vacuum Sealing: Arguably the easiest—just press a button and let the machine do the work.
  • Canning: The most labor-intensive and requires close attention for safe processing.

Shelf Life

  • Mylar Bags: With oxygen absorbers, dry foods can last up to 25–30 years.
  • Vacuum Sealing: Refrigerated or frozen foods last 2–3 years; shelf-stable items last 1–2 years.
  • Canning: Home-canned foods are best used within 1–2 years for top quality, though they can be safe much longer.

Let’s put this in perspective: If you want to store rice for the next decade or more, mylar is tough to beat. For keeping meats fresh in the freezer, vacuum sealing is a superstar. If you love shelf-stable, ready-to-eat soups or jams, canning wins the day.

Statistics: What Does the Data Say.

Let’s get down to numbers. Food storage isn’t just an art—it’s a science backed by research and data:

  • Mylar Bags: According to Utah State University Extension, white rice and wheat stored in mylar with oxygen absorbers can last up to 30 years. Powdered milk and dried beans can last 15–20 years.
  • Vacuum Sealing: Foods like steak can last up to 2–3 years in the freezer when vacuum sealed, as opposed to 6–12 months with conventional methods (USDA). Cheeses and deli meats stay fresh 2–3 weeks, compared to just a week in standard packaging.
  • Canning: The USDA recommends consuming home-canned goods within a year for best quality, but properly processed foods remain safe to eat for several years. Commercially canned foods can last 2–5 years, with some studies showing edibility up to 10 years or more if stored correctly.

And how popular are these methods. According to a 2022 Statista survey, about 45% of American households do some sort of home food preservation. Canning remains most popular (used by 32%), while vacuum sealing and mylar storage are rapidly catching up, especially among preparedness-minded consumers.

Fun fact: During the pandemic, sales of canning supplies increased by 600%, and vacuum sealer sales jumped over 300%. People are clearly taking food security more seriously.
