What Size Oxygen Absorber Do I Need?

I spent the better part of last weekend working on my food storage. For several months I have been building up my freeze dried foods and really haven’t done any work on my long term buckets. So I decided to purchase 50lbs of flour, 25lbs of sugar and 25lbs of rolled oats. Storing these bulk items, I thought that sharing my chart on O2 absorbers would be a great benefit to ya’ll.

How many O2 Absorbers

Here are some thoughts to ensure you maintain the freshest food possible for the longest time. You’ll no longer have the problem of oxidization or of insects that plague others’ food store who don’t utilize this wonderful science.

Oxygen absorbers take all oxygen out of your food so that it stays fresh longer. Undershooting on this will give you some benefit, but not the full effect it could have. A pack that is too small will not be able to keep up with the amount of space you have available.

Having too large of an oxygen absorber will not harm your food and will be effective. However, you will end up spending more than you needed. And who wants to do that, right?

There are nearly as many different ideas of what ratio to use as there are people who use them. Some use varying ratios for different foods based on their density. Items that store closely together with little air between food particles such as rice and beans need less cc (cubic centimeters). Foods such as pasta need more cc.

Thankfully, there’s a good rule of thumb that can be used generically. This will especially be helpful for those who are just starting out. Once you’ve used oxygen absorbers for a while, you’ll be able to follow your instincts a bit more.

Quart or pint-sized jars and bags will store fine with 50cc. A gallon requires around 300 cc. Five to six-gallon containers require up to 2000 cc depending on the item you are storing.

It’s helpful to have smaller oxygen absorber packets on hand in a pinch. You can combine several with small cc readings to get to the number of cc you need for a larger storage space.

Armed with the facts you now have, you’re ready to make an informed decision. A little cost will go a long way in keeping your food in much better condition for longer durations of time.
