The capacity of oxygen absorber varies, usually in cubic centimeters (cc). oxygen absorber are available in a variety of sizes, common sizes include 100cc oxygen absorbers，120cc, 200cc, 500cc and 2000cc. To determine the right size, match the calculated amount of oxygen with the corresponding deoxidizer capacity. The easiest way is to consult us and our professional sales manager will recommend the right deoxidizer for your product.

• Choose the right size oxygen absorber based on the size of your package

For example, if your package is irregular in shape, you may consider using several smaller oxygen absorbers to evenly absorb excess oxygen from the surrounding air. There are many types and sizes to choose from, so you can choose based on your specific requirements and needs.if your container has a volume of 10 liters (10,000 cubic centimeters), the oxygen volume would be 2100 cubic centimeters (10,000 x 0.21). You would then choose oxygen absorbers that can handle a total of 2100 cc. This might mean using multiple absorbers to reach the desired capacity.

These sizes will work for ALL food types:
50cc for a ½ pint
100cc for a pint
300cc for a quart
500cc for a gallon
2500cc for a 5 gallon

• Factors to Consider When Choosing Oxygen Absorbers

Type of Food Being Stored
The type of food plays a significant role in determining the amount of oxygen absorber required. Foods with higher fat content or those that are more prone to spoilage may require larger or additional absorbers.

• Packaging Material

The packaging material also affects the effectiveness of oxygen absorbers for food storage. For example, when oxygen absorbers are used in vacuum-sealed bags or oxygen absorbers for mylar bags with low oxygen permeability, they are more effective than ordinary plastic bags.

• Storage Conditions

Environmental factors such as temperature and humidity can influence the effectiveness of oxygen absorbers. Storing food in a cool, oxygen absorber for cookies，dry place will enhance the efficiency of the absorbers.

• Calculating the Correct Amount of oxygen absorbers

Calculating the correct amount of absorbent oxygens pack involves several steps and considerations. Here is a detailed overview of the process:

• Determining the Volume of the Container

The first step in calculating the correct amount of oxygen absorber that is required is to determine the volume of the container in which the food will be stored. This can be done using the formula for volume calculation based on the shape of the container, for example, cubic volume for rectangular containers and cylindrical volume for round containers.

• Calculating the Oxygen Volume

Next, you need to calculate the volume of oxygen present in the container. Since oxygen makes up about 21% of the air, you can calculate the oxygen volume by multiplying the total volume of the container by 0.21.

• Determine the Correct Amount of Oxygen Absorber

To determine the volume of oxygen that penetrates into the packaging during shelf life, you need to consider the oxygen permeability of the packaging material, the surface area of the packaging, and the shelf life of the packaged food. The oxygen permeability of the packaging material is typically provided by the supplier and is usually measured in units of cubic centimeters per square meter per day (cc/m²/day).

The surface area of the packaging material can be measured directly or calculated using the formula for the surface area of a rectangular prism. The shelf life of the packaged food is typically specified by the manufacturer or determined through testing and experimentation.

Using these values, you can calculate the volume of oxygen that penetrates into the packaging during the shelf life. This is done by multiplying the oxygen permeability of the packaging material by the surface area of the packaging and the shelf life. For example, if the oxygen permeability is 10 cc/m²/day, the surface area is 1000 cm², and the shelf life is 6 months, the volume of oxygen that penetrates into the packaging during the shelf life would be:

10 cc/m²/day × 1000 cm² × 183 days (6 months) = 183,000 cc

This value represents the total volume of oxygen that penetrates into the packaging during the shelf life and must be taken into account when determining the correct amount of oxygen absorber needed.
