Both these methods are used to remove the oxygen content from a package. Vacuum packaging achieves this by sucking out all air and then sealing the package. Nitrogen flushing forces the heavier nitrogen gas into packaging, pushing out the oxygen content. In both instances, some oxygen remains. It is estimated that when these methods are used there can be 2–3% of oxygen remaining. 30cc Oxygen Absorbers can then be used to capture the residual oxygen present.
If I use vacuum packaging or nitrogen flushing to package my goods, do I still need to use 30cc Oxygen Absorbers?
I need to freeze my product. How will that affect the effectiveness of my 30cc Oxygen Absorbers?
30cc Oxygen Absorbers more rapidly capture oxygen at room temperature. Under normal room conditions (20°C), packages will be oxygen-free within 24 hours. At a temperature of 6°C, packages will be oxygen-free within 48 hours. In 0°C to 4°C conditions, packages will be oxygen-free within 72 hours. Given the content moisture levels can differ widely, we suggest customers test for their own unique circumstances.
What are 50cc Oxygen Absorbers used for?
50cc Oxygen Absorbers are used in sealed packaging to: • Extend shelf life of dried foods, powders, and snacks. • Prevent mold and bacterial growth by removing oxygen. • Preserve beef jerky, dried meats, and protein powders. • Protect grains, dehydrated fruits, and flour from spoilage. • Stop oxidation in pharmaceuticals and electronics. They work best in airtight containers like Mylar bags, vacuum-sealed bags, and food storage jars.
How many 50cc Oxygen Absorbers should I use?
The factors to consider when calculating how many 50cc Oxygen Absorbers you require are: • The volume of the sealed package • The volume occupied by the food product. The 50cc Oxygen Absorber calculation isolates the volume of the food packaging void – sealed package volume less food weight – multiplied by 20%. The factor of 20% reflects that our atmosphere comprises 20% oxygen and 80% nitrogen. For those who like the numbers, the formula is:
(Sealed package volume – food volume) × 20%

How do I know if my 50cc Oxygen Absorber is working?
A new 50cc Oxygen Absorber will have a loose powdered feel when pinched. It should feel free of clumps and may feel warm (a by-product of the absorber working in a moist environment). Spent (or expired) 50cc Oxygen Absorbers can feel hard or crunchy.
How long does it take for 50cc Oxygen Absorbers to work?
50cc Oxygen Absorbers, once exposed to the atmosphere, begin to get to work immediately. That is why we suggest that unused 50cc Oxygen Absorbers should be resealed within 30 minutes to ensure the integrity of the product is maintained.
How can I be assured that the 50cc Oxygen Absorbers I received are new and ready to use?
We understand that Protection Experts Australia customers should feel confident they are receiving the best quality products. The unopened 50cc Oxygen Absorber bag might feel hard, but that is due to the vacuum seal as they are all clumped together. Once the bag is opened, the sachets will separate and should feel like the container sand/granules. All our 50cc Oxygen Absorbers are packaged with a quality check, called the ‘eye’. The indicating eye is packaged with the 50cc Oxygen Absorbers and will appear pink, showing that the package is sealed and oxygen-free. Should the eye appear purple, this indicates that oxygen has penetrated the packaging through possibly a puncture or poor seal and the 50cc Oxygen Absorbers have been compromised. In this instance, we ask that you contact our office immediately so that the problem can be rectified.

I don’t need to use them all, how can I store my 50cc Oxygen Absorbers so they last?
Store 50cc Oxygen Absorbers at room temperature (5°C to 30°C), away from direct sunlight. They should be stored in their sealed package or a glass jar with a gasketed lid. Select the smallest glass jar possible to minimise the oxygen the absorbers will remove from the jar. 50cc Oxygen Absorbers in a well-sealed container will cause the lid to pop down. The shelf life of a 50cc Oxygen Absorber is up to 18 months.
How long will it take a 50cc Oxygen Absorber to remove all the oxygen from my sealed bag/container?
How quickly 50cc Oxygen Absorbers remove oxygen from the atmosphere will depend on the conditions. In dryer climates, it may take up to a week for 50cc Oxygen Absorbers to fully activate. Warmer, humid climates however accelerate the process and may take only 48 hours for the same result.
I’m using 50cc Oxygen Absorbers, why aren’t my bags getting hard?
50cc Oxygen Absorbers trap oxygen. Given that air comprises 20% oxygen and 80% nitrogen, the absorber will only be removing the 20% of the atmosphere that is oxygen. The volume of nitrogen remaining will mean your bag will not deflate to the extent of the bag becoming hard or rigid.
