Mylar Bags for Storing Dehydrated Foods: Tips and Best Practices

The reason why mylar bags are popular lies in the fact that they provide some of the best protection to the dried foods in relation to light, oxygen, and moisture when compared to most of the everyday storage alternatives. Extension guidance also observes that Mylar-type bags are of good choice when dealing with large quantities of dry foods particularly when combined with oxygen absorbers to assist in preserving quality and minimizing the off-flavors.

Such additional protection is important since dehydrated foods may deteriorate in quality very fast. This happens when they regain moisture due to the presence of air. Poor packaging can even reduce the storage life, undermine the flavor and create a higher risk of spoilage even when the food appears dry.

Which dehydrated foods work best in Mylar bags?

Mylar bags are usable on foods that are really dry prior to being put in storage. A fruit is generally leathery in nature whereas a vegetable and a herb tends to be brittle or crisp. According to Michigan State, vegetables and herbs are usually dry with moisture levels of about 10 percent. Similarly, Cornell advice indicates that vegetables are dried to the brittle point as this is what makes it safer to store over a long period.

It implies that the finest of them are dehydrated apple slices, banana chips, berries, peppers, onions, carrots, herbs, and more. For that they need to be dried in a proper manner. Still soft, sticky, wet, or unevenly dried food cannot be stored.

Why should food be cooled before it goes into the bag?

Warm food may generate condensation after the bag is closed. Condensation is the last thing you would want in long term storage. Drying then allow the food to cool completely then package it to avoid possessing the undesired moisture in the bag.

It is one of those minor steps which individuals miss, yet it does make a difference. When dehydrated food is put into Mylar when it is still warm, any moisture that accumulates will negate all the hard work that you had done to dry it properly.

Should you use oxygen absorbers with Mylar bags?

For many dry foods, yes. According to Utah State Extension, oxygen absorbers could be placed in bags whose qualities were good as oxygen-barriers to increase the shelf-life and preserve the quality of the product. They are particularly handy when dehydrated foods that have already been dried, and which you desire as long term storage.

Nonetheless, oxygen absorbers are not a solution to improperly dried food. They aid in the control of oxygen, but do not eliminate trapped internal moisture. The food must be dry initially and the seal must be good or the food storage set up will also fail.

How full should a Mylar bag be?

A Mylar bag must be half-filled to be limited in excessive head space, and not too full so as to have a hard time closing it. Compacting food helps in minimizing air that is present in the package and also helps in sealing the bag in a clean way. The line of the seal is as important as the bag itself.

It aids also in the packing of similar items in sensible portions. Rather than opening a large bag one after another, most folks will do more efficiently with the smaller bags that are used on a regular basis. Then the other food stored remains intact until it is required. This is an applicable best practice on the understanding that the dry foods would need to be stored in airtight containers and avoided being exposed to air.

How should sealed Mylar bags be stored after packing?

Even a high quality bag is not enough to protect food against adverse storage conditions. The National Center of Home Food Preservation advises storing dried foods in cool and dry dark areas. It also observes that storage temperature is significant: most dried fruits have a shelf life of approximately 1 year at 60degF and a portion of 6 months at 80degF and vegetables tend to have half the shelf life compared with fruits.

This has been the reason that a pantry or a basement shelf or a storage bin in a cool room is normally more effective than a hot garage or a sunshine shelf in the kitchen. Heat accelerates the loss of quality, and thus the appropriate room can be as significant as the appropriate packaging.

What mistakes should you avoid when storing dehydrated foods in Mylar bags?

The most common errors include sealing food prior to its complete dryness, failure to undergo cooling or conditioning process and storage of the bags in hot environment. The other error is the belief that Mylar will produce a long shelf life only. As a matter of fact, the shelf life rests on the combination of the dryness of the food, the seal which is used in the packaging, the control of oxygen and the temperature used in the storage.

What is the smartest way to use Mylar bags for dehydrated foods?

The best and easiest one is dry the food, then cool it, condition the fruit when you need it, and then use good Mylar bags with oxygen absorbers to fully dry foods when the case requires it, then close it up and store it all in a cool, dark, and dry location. With such steps in mind, Mylar bags can be considered one of the most effective methods of preserving dehydrated foods and extending their lifetime.
