Can You Use Oxygen Absorbers with Dehydrated Food?
Dehydrated food has gained popularity in recent years due to its long shelf life and convenience for outdoor activities, emergencies, and everyday use. Many people are curious whether utilizing oxygen absorbers in conjunction with dehydrated food is beneficial or necessary. In this article, we will delve into the topic and explore the advantages, potential drawbacks, and proper usage of oxygen absorbers with dehydrated food.

Understanding Oxygen Absorbers
Oxygen absorbers are small packets that contain iron powder, activated carbon, salt, and a suitable moisture-absorbing material. The primary purpose of these packets is to assist in removing oxygen from sealed environments such as food containers and bags. By doing so, oxygen absorbers prevent spoilage, mold growth, insect infestations, and other deleterious effects caused by exposure to air.
Benefits of Using Oxygen Absorbers with Dehydrated Food
1. Extended Shelf Life: One of the key benefits of using oxygen absorbers with dehydrated food is the ability to significantly extend its shelf life. Oxygen, as known enemies of food preservation, can accelerate the deterioration process. By removing oxygen from the packaging, the growth of bacteria, yeast, and molds can be effectively slowed down, allowing the dehydrated food to stay edible for a longer period.
2. Enhanced Quality Retention: Oxygen exposure can cause a loss of flavor, color, and nutrient content in dehydrated food. By incorporating oxygen absorbers, you can maintain the original taste, appearance, and nutritional value of the food. This is particularly important when storing dehydrated fruits and vegetables that are known to be prone to discoloration and nutrient degradation due to oxidation.
3. Minimized Risk of Microbial Contamination: Oxygen absorbers create an anaerobic environment, inhibiting the growth of spoilage microorganisms. This reduces the risk of foodborne illnesses and ensures the safety of the dehydrated food, especially when consumed over an extended period.
The Science Behind Oxidation and Its Effects on Dehydrated Food
Oxidation is a chemical process that occurs when molecules react with oxygen. This process is responsible for the degradation of food, promoting rancidity, discoloration, and nutrient loss. Dehydrated food is particularly susceptible to oxidation due to the removal of moisture during the drying process.
When dehydrated food comes into contact with oxygen, the fats and oils within it react and turn rancid, resulting in an unpleasant taste and smell. Additionally, vitamins such as vitamins A, C, and E, which are sensitive to oxygen exposure, can rapidly deteriorate, leading to a decrease in nutritional value. Therefore, it becomes crucial to minimize oxygen levels when storing dehydrated food for extended periods.
Potential Drawbacks of Oxygen Absorbers
While oxygen absorbers offer numerous benefits, it is important to consider some potential drawbacks:
1. Packaging Issues: The use of oxygen absorbers requires proper packaging to ensure effectiveness. Food should be stored in airtight containers to prevent oxygen from seeping back in. Inadequate packaging can render the oxygen absorbers useless, failing to provide the desired preservation effects.
2. Moisture Sensitivity: Oxygen absorbers are moisture-sensitive, which means that if they are exposed to moisture before being sealed in the food packaging, their functionality could be impaired. It is crucial to handle and store oxygen absorbers in a dry environment and use them immediately after opening the packaging.
Proper Usage and Storage Guidelines for Oxygen Absorbers and Dehydrated Food
1. Selecting the Right Size: When choosing oxygen absorbers, it is important to consider the volume of the dehydrated food being stored. Determining the appropriate size ensures that the absorber can effectively remove oxygen from the given space.
2. Packaging and Sealing: Place the dehydrated food in airtight and moisture-free packaging. This could include Mylar bags, mason jars with vacuum-sealed lids, or food-grade plastic containers with tight-fitting lids. It is crucial to remove excess air from the packaging before sealing it.
3. Calculation of Oxygen Absorbers Needed: To determine the appropriate number of oxygen absorbers, it is necessary to consider the oxygen transmission rate of the chosen packaging material. This can be found on the packaging or obtained from the manufacturer. Numerous online calculators are available to simplify this process.
4. Storage Conditions: Store the packaged dehydrated food in a cool, dark, and dry place. Exposing the food to sunlight, heat, or fluctuating temperatures can compromise the effectiveness of both the dehydrated food and the oxygen absorbers.
In conclusion, utilizing oxygen absorbers with dehydrated food can significantly enhance its shelf life, retain quality, and minimize microbial contamination risks. By removing oxygen, the growth of spoilage microorganisms, deterioration due to oxidation, and loss of vital nutrients can be prevented. However, proper packaging, handling, and storage techniques are essential to ensuring the desired results. By following the guidelines provided, you can confidently incorporate oxygen absorbers into your dehydrated food storage practices, extending its usability without compromising taste, color, or nutritional value.
