Vacuum Sealing vs. Oxygen Absorbers: The Ultimate Food Preservation Showdown

Vacuum Sealing vs. Oxygen Absorbers: The Ultimate Food Preservation Showdown

Posted by Avid Armor on Jun 20th 2023

When it comes to preserving food, two popular methods stand out - vacuum sealing and using oxygen absorbers. While both have their merits, vacuum sealing has proven to be more efficient in several aspects. In this blog post, we'll dive into the reasons why vacuum sealing is a superior choice for food preservation compared to oxygen absorbers.

Complete Removal of Air

One of the main advantages of vacuum sealing is its ability to remove almost all the air from the packaging. Oxygen absorbers, on the other hand, only remove the oxygen. By eliminating air completely, vacuum sealing significantly reduces the chances of oxidation, spoilage, and the growth of bacteria and mold. This ensures that your food remains fresh and safe to eat for extended periods.

Extended Shelf Life

Vacuum sealing can significantly extend the shelf life of various food items, often much longer than what can be achieved with oxygen absorbers alone. This is because vacuum sealing not only removes oxygen but also prevents the exchange of air, moisture, and odors between the sealed food and its surroundings. As a result, vacuum-sealed food can last up to five times longer than food preserved with oxygen absorbers.

Better Preservation of Flavor and Texture

Another benefit of vacuum sealing is its ability to preserve the flavor, aroma, and texture of food. By preventing the loss of volatile compounds and minimizing exposure to air, vacuum sealing ensures that your food remains as delicious and fresh as the day it was sealed. In contrast, oxygen absorbers may not provide the same level of protection for these aspects of food quality.


Vacuum sealing can be used for a wide range of food items, including dry goods, meats, fruits, and vegetables. This makes it a versatile solution for all your food preservation needs. Oxygen absorbers, on the other hand, are typically more suitable for dry goods, such as grains, nuts, and dehydrated foods. This limited scope can be a drawback for those looking for a comprehensive food preservation method.

Less Waste and Cost-Effective

Vacuum sealing bags and rolls can be cut to the exact size needed for each food item, minimizing waste. Additionally, vacuum sealing bags can often be washed and reused, making them a more cost-effective option in the long run compared to oxygen absorbers. This is especially important for those who are conscious about their environmental impact and want to reduce waste in their food preservation efforts.

Overall, vacuum sealing offers a more efficient and versatile method for preserving food quality, extending shelf life, and reducing waste compared to using oxygen absorbers alone. By investing in a high-quality vacuum sealer, you can ensure that your food remains fresh, flavorful, and safe to eat for longer periods, making it a valuable addition to any kitchen.
