can you vacuum seal dehydrated foods


With the rise in popularity of dehydrated foods, many people wonder if vacuum sealing is a suitable method to preserve them. Dehydrated foods offer numerous advantages, such as extended shelf life, lightweight, and retaining most of their nutrients. Vacuum sealing, on the other hand, is a popular preservation technique that involves removing air from the packaging to prevent spoilage. In this article, we will explore whether vacuum sealing is a viable option for preserving dehydrated foods and discuss its benefits and potential drawbacks.

Understanding Dehydrated Foods

Before delving into the topic, it is essential to understand what dehydrated foods are. Dehydration is the process of removing moisture from foods to prolong their shelf life. This is typically achieved by exposing the food to low heat for an extended period, drying it out and preventing the growth of spoilage microorganisms.

Dehydrated foods come in various forms. You can find dehydrated fruits like apples, bananas, and berries, as well as vegetables like carrots, peas, and tomatoes. Additionally, jerky and powdered foods are also common examples of dehydrated products. These foods are popular among hikers, campers, and individuals looking for convenient, lightweight meals with extended shelf life.

The Pros of Vacuum Sealing Dehydrated Foods

1. Increased Shelf Life: Vacuum sealing dehydrated foods can significantly extend their shelf life. By removing the air from the packaging, the growth of spoilage-causing bacteria and mold is minimized, allowing the food to stay fresh for an extended period.

2. Preserve Nutritional Value: Dehydrated foods already retain most of their nutrients. Vacuum sealing helps maintain these nutrients by protecting them from exposure to oxygen, moisture, and light, which can degrade their nutritional content.

3. Aids in Portion Control: Vacuum sealing allows you to portion your dehydrated foods appropriately, preventing waste. You can seal them in smaller quantities that suit your needs, making it more convenient for future consumption.

4. Protects Against Freezer Burn: If you plan to freeze your dehydrated foods for a longer duration, vacuum sealing helps protect them from freezer burn. Freezer burn can occur when food is exposed to air, resulting in unpleasant taste and texture. Vacuum-sealed packaging prevents air from coming into contact with the food, maintaining its quality even after being frozen.

5. Convenience: Vacuum-sealed dehydrated foods are highly portable and can be easily stored in a backpack or pantry. They are lightweight, reducing the burden of carrying heavy food supplies during outdoor activities.

The Potential Drawbacks of Vacuum Sealing Dehydrated Foods

1. Crumbling: Some dehydrated foods, particularly fruits and vegetables, may become brittle and crumble during the vacuum sealing process. This can affect their texture and appearance when rehydrated. To minimize this issue, pre-freeze the food slightly before vacuum sealing.

2. Moisture Absorption: While vacuum sealing prevents moisture from entering the packaging, it cannot eliminate moisture entirely. If dehydrated foods are not adequately dried before sealing, the remaining moisture can contribute to microbial growth and spoilage.

3. Limited Reusability: Once you open a vacuum-sealed package, its preservation benefits diminish. While you can still consume the food, it is advisable to consume it within a reasonable time to ensure quality and freshness.

4. Equipment Cost: Vacuum sealers can be a significant investment depending on the model and features. Some vacuum sealers may require additional accessories, such as specialized bags or canisters, which can further increase the cost. However, this cost can often be justified by the long-term benefits of preserving food.

5. Potential Flavor Loss: In some cases, vacuum-sealed dehydrated foods may lose a small amount of flavor due to the removal of air. However, this varies depending on the type of food and personal taste preferences. Adding seasonings or marinades before vacuum sealing can help mitigate any flavor loss.


Vacuum sealing dehydrated foods is a suitable method for prolonging their shelf life and maintaining their nutritional value. It offers several advantages, including increased storage time, excellent portability, and protection against freezer burn. While there are some potential drawbacks to consider, such as crumbling or slight flavor loss, these can typically be managed with proper technique and preparation. Ultimately, vacuum sealing can be a valuable tool to preserve the quality and freshness of dehydrated foods, making it an excellent choice for outdoor enthusiasts, preppers, and anyone seeking long-lasting food options.
