Can You Vacuum Pack Dehydrated Food?


Vacuum packing is a popular method of food preservation that helps in prolonging the shelf life of various food items. But what about dehydrated food? Can you vacuum pack it too? In this article, we will delve into the world of dehydrated food and explore whether vacuum packing is a suitable storage method for it. Let's unravel the mysteries of vacuum packing and find out whether it is an effective technique for preserving dehydrated food!


Understanding Dehydrated Food

Dehydrated food is food that has been dried to remove its moisture content. This process makes the food lightweight, easy to store, and less prone to spoilage. By removing moisture, the growth of bacteria, yeasts, and molds is inhibited, which significantly extends the shelf life of the food. Common examples of dehydrated food include dried fruits, vegetables, herbs, and jerky.


1. The Benefits of Vacuum Packing Dehydrated Food

Vacuum packing dehydrated food comes with several advantages. Let's take a look at some of them:


Extended Shelf Life: Vacuum packing removes oxygen from the packaging, which helps in preventing the growth of aerobic bacteria that require oxygen to survive. This absence of oxygen significantly prolongs the shelf life of dehydrated food.


Retained Nutritional Value: The vacuum sealing process protects the food from exposure to air, light, and moisture, which can cause nutrient degradation. By preserving the nutritional value, vacuum packing ensures that you can enjoy the same health benefits from dehydrated food as you would from fresh food.


Protection against Freezer Burn: If you plan on storing dehydrated food in the freezer, vacuum packing is an excellent way to protect it from freezer burn. Freezer burn occurs when moisture from the food evaporates, leaving behind dry and discolored patches. Vacuum packing prevents moisture loss and safeguards the quality of the dehydrated food.


2. Considerations before Vacuum Packing Dehydrated Food

While vacuum packing dehydrated food has its advantages, there are a few things to keep in mind before proceeding with this preservation method:


Moisture Content: Before vacuum packing dehydrated food, it is crucial to make sure that it is sufficiently dry. Even a small amount of moisture can promote the growth of bacteria and mold, rendering the vacuum packing useless. Ensure that the food has been dehydrated thoroughly, following the recommended guidelines.


Size and Shape: Consider the size and shape of the dehydrated food items you intend to vacuum pack. They should fit comfortably into the vacuum sealing bag or container without any overlapping or bulging. This will ensure an airtight seal, preventing the entry of oxygen.


3. The Vacuum Packing Process for Dehydrated Food

Now that we have discussed the benefits and considerations, let's go through the vacuum packing process for dehydrated food:


Select Appropriate Packaging: Choose suitable vacuum packaging bags or containers specifically designed for food storage. These should be airtight and made of materials safe for food contact.


Fill and Seal: Take your dehydrated food items and carefully place them into the vacuum packaging bags. Leave enough space at the top to facilitate sealing. Use a vacuum sealing machine or device to extract the air from the bag and seal it shut. Alternatively, if using containers, follow the instructions provided by the manufacturer for proper sealing.


Label and Store: Once sealed, label the packages with the contents and date of packaging. This will help you keep track of the stored food items. Store the vacuum-sealed dehydrated food in a cool, dark, and dry place away from direct sunlight and extreme temperatures.


4. Shelf Life and Storage of Vacuum Packed Dehydrated Food

The shelf life of vacuum packed dehydrated food depends on various factors, including the type of food, moisture content, and storage conditions. On average, vacuum packed dehydrated food can last anywhere from 6 months to 2 years.


To maximize the shelf life, ensure that the food is completely dehydrated before vacuum packing. Store the vacuum-sealed packages in a cool and dry environment, as exposure to heat and humidity can shorten the shelf life. Regularly check the packages for any signs of spoilage, such as off smells, discoloration, or mold growth. If you notice any of these indicators, discard the food immediately.


5. Specific Considerations for Different Types of Dehydrated Food

Different types of dehydrated food may require specific considerations when vacuum packing. Here are a few examples:


Dried Fruits: Before vacuum packing dried fruits, it is recommended to freeze them for 48 hours. This step helps to kill any potential insect larvae and eggs that could cause spoilage during storage.


Jerky: For vacuum packing jerky, it is crucial to ensure that the slices are not too thick. Thin slices will lead to better preservation and eliminate the risk of oxygen pockets.


Herbs: When vacuum packing dehydrated herbs, it is advisable to crush them slightly to release their natural oils. This will enhance the flavors and aromas of the herbs when used in culinary preparations.


In conclusion, vacuum packing is indeed a suitable storage method for dehydrated food. It offers numerous benefits, including extended shelf life, retention of nutritional value, and protection against freezer burn. By understanding the process and considering specific factors, you can effectively vacuum pack various types of dehydrated food and enjoy their preserved goodness for an extended period. So, go ahead and give vacuum packing a try - your dehydrated food will thank you for it!
