How Long Does Dehydrated Food Last If Vacuum Sealed?

How long does dehydrated food last if vacuum sealed? Food that has been dehydrated may survive for up to two years. Nonetheless, it is dependent on the relative humidity in the air prior to vacuum sealing.

Well, vacuum-sealed dehydrated food may survive for up to 30 years if done correctly. To guarantee long-lasting food, it is necessary to prepare the food, know the optimum temperature to use while dehydrating it, and have adequate storage.

You will be OK if you keep oxygen and moisture from accumulating in your meal.

Are you afraid you may get lost in a jungle while camping and starve to death? We realize that transporting a large amount of food and preparing it while camping might be difficult. Then why don’t you bring dehydrated, vacuum-sealed food with you? Because that is long-lasting.

How Long Can Vacuum Sealing Add To Your Dehydrated Meal?

If you know the appropriate way, you can keep food for that long. Dehydrated food typically lasts 5–10 years, but it might survive as long as 30 years if vacuum packed. Yes, vacuum-sealed packages of dried food survive that long.

If you are lazy and like to preserve your food or enjoy camping and need to transport a large amount of food, you will have to keep an eye on the meal to ensure it does not become ruined.

The best choice for you is to dehydrate and vacuum seal the dried food because so much of this stuff has a 25-year shelf life.

Most goods now have a 20–30 year shelf life, whereas meat and fish only have a 3-5 year shelf life. You will be set to go for years if you follow the appropriate dehydration and vacuum sealing steps.

Why not dehydrate food and then freeze it to extend the period it can be kept without going bad? This is OK as long as you understand that it depends on the sort of food you are drying and freezing and that you will need to vacuum seal it as soon as possible.

I will walk you through the process of vacuum sealing and dehydration, which is the most basic scenario.

What Is Dehydrating Of Food?

How Long Does Dehydrated Food Last If Vacuum Sealed

One of the easiest methods to preserve food is to dehydrate it. Drying has been used to keep food fresh without using the fridge for ages, and it is one of the quickest and cheapest methods to preserve your produce. It may also reduce the weight of camping and hiking gear, saving your shoulders without breaking the bank.

Dehydrating your food significantly decreases moisture, enabling it to survive longer while still tasting good.

This is due to the fact that drying your food decreases its moisture content by 5 to 20%. Bacteria that cause food degradation are unable to thrive at those temperatures. You can prolong the life of your favorite foods by eliminating moisture from them.

Types Of Dehydrating

There are many techniques for dehydrating foodstuffs, but some are more effective than others. Because contemporary techniques have helped to enhance the pace of dehydration, your food will be less likely to deteriorate.

The following are the most widely used techniques today:

  • Sun Drying: Sun drying is a technique of food preservation that is as old and simple as it is effective. Around 12,000 years ago, people began cutting fruit and stringing it on racks or strings in the sun to dry. Sun drying is very effective when it is possible to sit out in the sun for long periods of time.
  • Air Drying: Dehydrating food by air drying is a method that dates back to prehistoric times. Because air drying takes place in the shade, it is the primary difference between sun drying and air drying. Since the sun’s rays are a threat, this technique helps safeguard anything that needs to be shielded from the light. As a general rule, it is excellent for fragile greens like herbal ingredients.
  • Drying Through Oven: Oven drying is a method of gently drying food in your home oven at temperatures of about 140 degrees Fahrenheit. Ovens are not the most effective dehydrators on the market since they are so big.

However, if speedy drying is a must, they may save you the effort of purchasing an additional appliance. In addition, because you will need to leave the door open to allow the moisture out, it may also heat your home.

If you consider drying food in your oven, do it on a low setting. Anything over 140 degrees Fahrenheit will burn your food rather than dry it.

  • Drying Using A Dehydrator: Electric dehydrators combine modern technology with traditional drying methods. These little powerhouses include fans and components to dry your food quickly. That means minimum spoiling and a wonderful end result.

A temperature indicator and an adjustable dial are standard features on most electric dehydrators. It depends on the data. This may help accelerate or delay drying. If your dehydrator has a fan, place it in the garage or somewhere quiet.

Follow this tip if you want to use your dehydrator in the summer without making your home too hot. You can get OSTBA Food Dehydrator from Amazon. The food dehydrator is meant to be easy to use. It is simple to keep clean and store.

It may be readily cleaned after the meal has dried using a moist cloth or brush/sponge. If you get damaged trays, you may contact their customer service. Within the warranty time, they provide a free replacement service.

What Is Vacuum Sealing?

How Long Does Dehydrated Food Last If Vacuum Sealed

It is also known as vacuum packing, and it is a food storage method that involves sucking all of the air out of a food container before sealing it.

It may be done mechanically using a vacuum sealer or manually with customized bags that include a valve and a mechanical suction pump to remove the air in the bag before sealing it.

The term “food storage” refers to the storage of food, but it may also refer to the storage of clothes, blankets, and sheets, as well as the storage of other materials that need preservation in an oxygen-free environment, such as metal fasteners, bolts, and tools.

However, it is not a panacea for long-term food preservation. Along with its benefits, it also has certain disadvantages that should be addressed before putting it into practice.

How Food Can Last Longer When Vacuum Sealed

Everything is now vacuum-sealed and dried. Do not forget to monitor the temperature, humidity, and light levels. Also, double-check the vacuum seal.

To be extra safe, separate the food packs. Plus, there are some great reusable bags available. Some are made for camping and other outdoor activities. And keep your vacuum-sealed food in them.

Food preservation requires more than double wrapping. Check for rats and other scavengers in your food. Therefore, planning food storage for camping is a great idea. We have another idea.

If you do not want bears or other wild animals to eat your food, keep the vacuum-sealed packets securely closed after use. Because the bags’ stench may attract animals.

So, there you have it: the key to preserving dehydrated food. There is more to say about this, and it is vital. To make food last longer, it must first be processed appropriately. It will not survive long if not properly cared for. It is merely logic.

So, here is the procedure:

What Are The Best Ways to Vacuum Seal Dehydrated Food?

How Long Does Dehydrated Food Last If Vacuum Sealed

This procedure is broken down into three simple phases. You will not have to worry about bad food when camping or on other trips once you have mastered this. Follow these procedures, and you will be vacuum-sealing your food in no time.

Prep For Vacuum Sealing

This is the most important part of the directions. As simple as the preparation may seem, it must be carried out with extreme caution.

The first thing to remember is that it will shrink significantly after the food is dried. Four hundred grams of apple, for example, would provide a single cup of dry slices. As a result, you must understand portion sizes and properly cut your fruits, veggies, and meat.

Slice them into 3mm pieces since that is a perfect size. Because it is a little pocket knife, you may complete the work with a griptilian knife. Try Griptilian 551 Knife by Benchmark Store for your fruit cutting needs.

The lightweight build of this knife and the handle grips make it easy to grip and slice with it. In addition, the changeable pocket clip allows for maximum convenience.

Now, before you dry and vacuum seal your low-acid veggies, be sure you steam them first. Steam them for at least ten minutes before drying them.

To prevent browning, lemon juice may be added to fruits and veggies juice. You may also use ascorbic acid to bathe your veggies, which works just as well as lemon juice.


During dehydration, two factors must be addressed. First, when dehydrating food, make sure the temperature and moisture levels are optimal. A little error here might lead to food deterioration. In this way, your vacuum-sealed food may spoil.

It isn’t easy to know what temperature to dehydrate food at. We often use too high a temperature without considering the food. Consequently, a good dehydrator and the correct dehydrator temperature are needed.

We are frequently tempted to raise the temperature to speed up the process. So the fruit and vegetables get a strong outer shell and a gooey center.

A high temperature also destroys the helpful enzymes. This means the meal’s micronutrients are more likely to be lost. As a consequence, all benefits are gone.

Meat, for example, can endure greater temperatures than most fruits and vegetables. Most dehydrators now provide suggestions for the ideal temperature for each fruit or vegetable. So follow those instructions.

Low-moisture fruits generally stay longer than dried items. Moisture promotes mold growth in certain meals. Moisture is bad for dehydrating food.

When is it dry enough to eat? Fruits and vegetables with brittle skin and wrinkly edges are beyond their prime. Please keep them in a dehydrator or zip bag to distribute the residual moisture uniformly and remove any damp patches.

This is called conditioning. Fruits like apricots and plums are sticky and juicy. However, unlike potatoes and beans, they have a shorter shelf life.

Preserving the Food Vacuum-Sealed

To minimize oxidation, vacuum seals the food as soon as you chop it down and pack it. You may also double bag them in a heat-sealed bag. This will help preserve the food’s nutrition. This is how to keep dehydrated food. After the sealing, there is not much to do.

It is vital to preserving food at the correct temperature and location. Food must be kept clean and away from light. The temperature may destroy nutrients in food.

Meat and fish may rapidly become rancid when stored. Meat cannot be stored at room temperature. So keep them frozen to lengthen their vacuum-sealed life. You can use oxygen absorbers with vacuum seal bags.

These suckers suck up air and make your meal last longer. O2frepak 200CC(100-Pack) Food Grade Oxygen Absorbers off Amazon works extremely well for food storage purposes.

Finally, an appliance that will help you do the deed itself is a vacuum sealer. Take a look at GERYON Vacuum Sealer Machine for your vacuum sealing needs.

Advantages Of Vacuum Sealing

A vacuum sealing machine has many benefits that you may want to weigh before making the purchase:

  • Food vacuum sealers help you conserve time. Freeze individual portions of snacks or veggies or family-sized quantities of meals. Fix the servings you will need when it is time to dine and you are done. Dinner has been served.
  •  Vacuum sealers are cost-effective. You may keep fresh meat on hand for up to 5 months by purchasing meat in bulk, separating it into meal-sized quantities, and sealing it. This saves you a lot of money over purchasing meat over the counter every time you have to eat.
  • Using vacuum sealing may help increase the longevity of food goods. When food is vacuum-sealed, it retains its freshness for a longer period of time. Food preserved via vacuum sealing lasts three to five times longer than food kept in plastic boxes or packets. Storage conditions affect how long vacuum-sealed food preserves depending on where it is kept: in the fridge, the freezer, or even the basement.
  •  Any residual food from your dinner should be vacuum-sealed straight away. You will not have to throw the food out, and you will have another quick dinner to fix in the future. The remaining pieces may be frozen and used after several months, preventing you from eating the same dish three times in a row. After a few weeks, you can take it out for a flavorful supper.
  •  Vacuum-sealed packaging is more efficient and well-organized. Vacuum-sealed food saves room in your refrigerator or freezer and makes it easier to see what you are storing.

Disadvantages Of Vacuum Sealing

  • Both manned and automated, vacuum sealers need thicker, tougher bags than regular plastic bags. Because non-vacuum-sealed plastic bags are semi-permeable to gasses, they may let some air in. As a result, food vacuum-packed in a normal plastic bag may well not survive as long.
  • Vacuum sealers of good quality are not cheap. Vacuum sealers for beginners cost approximately $80. The very excellent commercial-grade ones cost upwards of $350. There are less expensive vacuum sealers on the market, but they only operate with smaller bags.
  • Foods having a soft crust, such as bread with a soft crust, pastries, and confections, cannot be vacuum-packed. The cavities in between these pastries are drained out, breaking the structure of the meal since vacuum sealing eliminates air from within a container and everything in it. The vacuum bag also compresses and smashes them, destroying their texture.
  • Even if vacuum-sealed, fruits and veggies naturally generate a ripening agent called ethene will continue to mature and eventually rot. Bananas, oranges, plums, mangoes, and other fruits are examples. The ethylene gas builds up within the vacuum bag, causing the fruit to ripen quickly. Furthermore, there is minimal value to vacuum-sealing fresh vegetables. The inherent enzymes of plants and vegetables gradually break them down, converting fresh food into a mushy mess.
  • Not every vacuum-sealed bag may be reused. The most prevalent kind of bag on the market is the non-reusable bag. These are one-time-use bags that do not have a zipper closing like Ziploc bags.


How long does dehydrated food last if vacuum sealed? A very long time if you do it correctly. Despite the many drawbacks of vacuum sealing foodstuffs, the benefits exceed the drawbacks in the majority of cases.

Furthermore, some approaches may be taken to mitigate and overcome these drawbacks. However, vacuum sealing increases the shelf life of food while also preserving its quality, so we suggest that you use it as much as possible.
