How to Store Dehydrated Food & Pack Meals for the Trail

This page covers storing dehydrated food at home, and how to vacuum seal meals for backpacking trips.

Having a problem with vacuum seal bags getting punctured by the sharp parts of dried food?

Try the packing technique described in the section on vacuum sealing backpacking meals.

Go ahead and take a photo of your beautifully dried vegetables that will go into your backpacking meals, but don’t let them sit out in the open too long. Oxygen and moisture are the enemies of dehydrated food.

Using Oxygen Absorbers for Dehydrated Food Storage

As food comes out of the dehydrator, weigh it or measure it by volume. That way you can decide if you have dried enough of each food. Once the dried food has cooled, place it in a jar with a tight fitting lid. Jars are more economical than disposable vacuum seal bags for home storage, and there’s no plastic waste. For short-term storage of a month or two, there won’t be much negative impact on dried food if stored in jars without oxygen absorbers. For long term storage in jars, use oxygen absorbers.

Oxygen absorbers do a fine job of gobbling up oxygen, and they only cost a few pennies each. With oxygen absorbers, you can reuse jelly, sauce, and pickle jars. Clean and dry the jars and lids thoroughly before repurposing them for dehydrated food storage.

Use the smallest jar that will hold the dried food. There will be less oxygen to remove if the jar is filled all the way.

Use a 50-cc absorber for half-pint jars, 100 cc for pint jars, and 300 cc for quart jars. You may want to use the 100-cc size oxygen absorbers for all jars; use 2 or 3 of them for large jars.

Once you open a package of oxygen absorbers, take out what you need for immediate use, and transfer the rest to a glass jar.

Exposure to light impacts the quality of dried food over time. Store jars in a dark place. A chest of drawers blocks light and makes accessing the jars easy. Label the lid of the jar with the name of the food and the date dried.

Oxygen-absorber suppliers usually sell Mylar food storage bags, which can be used together with oxygen absorbers. Mylar bags are an option for storing dehydrated food. You don’t need a vacuum sealer if you pack meals in Mylar bags. You can seal them with an iron. One advantage of using Mylar bags with oxygen absorbers is that the bags don’t scrunch up around the sharp edges of dried food, which sometimes causes vacuum sealed bags to fail.

See Heat Sealing Mylar Bags. This is the website of PackFresh USA. They also sell oxygen absorbers.

Mason Jar Vacuum Sealing Accessory

If you own a FoodSaver vacuum sealer, you can vacuum the air out of canning jars with a jar sealing accessory. The accessory only works with vacuum sealers that have a tube port. The kit comes with a connecting tube and two attachments you place over either wide-mouth or regular-mouth canning jars.

FoodSaver no longer makes the jar sealing accessory, but another manufacturer has filled the void:

Backpacking Food Storage of Meat

As long as the meat you dry is low-fat, it will keep well in jars with oxygen absorbers or in jars that are vacuum sealed with the FoodSaver accessory. I have stored dehydrated meat for up to a year in jars. If you want to go longer than a year, or if you just want peace of mind, you can vacuum seal the dried meat in vacuum bags, and place the meat in the freezer. When taking dried food out of the freezer, allow the food to return to room temperature before opening the bag. Otherwise, condensation may form on the food.

Packing Dehydrated Meals and Snacks

Meals fit in sandwich-size bags, but for larger servings, quart-size bags work best. Quart-size bags are usually thicker than sandwich bags, so they will also do a better job of keeping sharp dried food from poking through them. Snack-size bags, besides holding single servings of snacks, can be cut down in size to hold powdered ingredients like milk and cheese powders. Cut the snack bag in two places two inches from each side. Reseal the cut sides with tape.

Ziploc and Glad brands are good quality bags to pack meals and snacks in. Wal-Mart Great Value brand plastic bags are thin and puncture easily.

The photo above shows the ingredients for Mexican Beef & Rice packed in a sandwich-size bag with the powdered taco seasoning and milk/cheese powders enclosed in smaller bags. The powdered ingredients are packed separately because they are added to the meal after the meal boils for a minute.

Dehydrated backpacking meals ready for the final step in dehydrated food storage: vacuum sealing.

The photo above shows large-portion dehydrated meals assembled in quart-size bags, ready to be vacuum-sealed for transport or storage.

If heading out for only a few days and not doing resupplies, packing daily rations in gallon-size Ziploc bags is sufficient for most conditions and will keep you organized. Long distance backpackers and canoe campers will benefit from vacuum sealing food.

Compostable Bags for Packing Backpacking Food

Looking to reduce your use of plastics?

Quart, sandwich, and snack-sized bags from Responsible Products are durable enough to pack your backpacking meals and snacks in. You can reuse them several times, and then turn them into your compost pile. They are made of 100% plant materials and will break down over time when exposed to oxygen, moisture, and bacteria.

Responsible Compostable Bags

I tested these Responsible Products bags for puncture resistance by putting dehydrated bowtie pasta in the bags and banging on the bags. As expected, the sharp pasta made a few pinholes in the bags. I also tested Ziploc sandwich bags, which also developed puncture holes. I conclude that they are as suitable as plastic bags for packing backpacking meals in, since you’re not likely to bang on your meals like I did. Quart-size Ziploc freezer bags are made of thicker plastic and are more puncture resistant.

The Responsible Products bags are easy to close with a good seal, and the closures continue to work well after several uses.

These compostable bags are water resistent, but they are NOT suitable for freezer-bag cooking where boiled water is added to ingredients in the bag.

Compostable bag sizes.

Responsible Products sandwich-size bags are an inch longer than Ziploc sandwich-size bags, so they work well for large portion backpacking meals. The RP snack-size bags are half an inch longer than the Ziploc brand. The quart-sizes are the same for both brands. If possible, pack meals in the sandwich-size compostable bags, as they cost about two cents per bag compared to four cents per bag.

Benefits of Vacuum Sealing Dehydrated Meals

  • Protects food from moisture which could cause mold growth.
  • Preserves the nutritional quality and appearance of dried food by removing oxygen. Prevents any oil or fat from going rancid, although you should still stick with minimal fat and oil in meals.
  • Seals in food odors, a benefit in bear habitat.
  • Slows down chewing mice that like a good romp through your food bag in the night.
  • Compresses food so it takes up less space.
  • Keeps daily rations easily accessible and the remaining days undisturbed.
  • Keeps food safe if mailed ahead to places along the trail where you will pick it up weeks or months later.

How to Vacuum Seal Dehydrated Meals

Are your vacuum sealed bags getting punctured by sharp dried food?

The following method of wrapping each meal in a paper towel reduces the number of vacuum bag seals that fail down to about ten percent. If a seal fails, you will know it within 24 hours, and you can see that the contents of the bag are no longer scrunched up.

Pack meals in quart-sized freezer bags. Before filling the bags, write the name of the recipe, the amount of water needed for cooking, and the date packed on the outside of each bag.

Place each filled bag on top of a paper towel. Flatten out the ingredients to fill the bag completely and evenly. By positioning any bags of powdered ingredients across the top, with no food above or below, you won’t create any bulges.

Fold bag and paper towel in half. Then, pull up the sides of the paper towel, and apply tape to attach. Apply 3 more pieces of tape to the longer open side. Write the name of each meal on the outside of the paper towel.

Vacuum Sealing Steps

  • Cut each bag to length (11 inches long is usually sufficient for 2 meals).
  • Seal one end. Double-seal to improve results.
  • Insert meals wrapped in paper towels.
  • Seal other end.
  • Write the date on the bag, so you know to use it before other meals dried later.

This method of storing dehydrated meals is also ideal for emergency home storage. If an emergency strikes, and you have to leave your home, you won’t have time to fiddle around with assembling meals from a stash of dried ingredients stored in jars. Be ready to go with a supply of ready-to-eat meals.

Vacuum Sealing Daily Rations

If you’re a solo hiker and your meal portions are not large, you may be able to vacuum seal all the food for a day on the trail in a single vacuum seal bag. This is a great way to stay organized.

Vacuum sealing daily rations.

Leave the inner bags unsealed. Put a small slip of paper between the seals of the bags to keep them from sealing all the way. When you vacuum seal the outer bag, the air will get squeezed out of the bags inside. Exception: Close the 2 x 3 bags containing powders since the powders will have displaced the air already and you don’t want any powder to get sucked into your vacuum sealer.

Cut continuous eleven-inch wide rolls twelve inches long, or longer if needed.

Seal one end of the bag. You can seal it twice to improve the odds that the seal will hold.

Fill the bag with your food for the day.

Enclose a paper towel with your menu written on it. Enclosing a second paper towel below the food can help reduce the chance of sharp dried food piercing the delicate lining of the vacuum seal bags. The paper towels come in handy for clean-up and for toilet paper.

Each day’s rations weigh about a pound and a half.
