Quick Reference Oxygen Absorber Chart:

Here is a handy “Quick Reference Oxygen Absorber Chart” that indicates the MINIMUM size of Oxygen Absorber(s) that you should use for various different kinds of dry food types that are placed inside a sealed MylarPro Bag. Oxygen Absorbers are rated by the number of cc’s (Cubic Centimeters) of Oxygen that they will absorb and this chart will show you the corresponding number of cc’s of Oxygen that needs to be removed from the four most common sized containers.  There are no adverse effects to using an absorber larger than required.

* This Quick Reference Oxygen Absorber Chart shown above assumes that you have vacuumed or forced out most of the excess air inside the MylarPro Bag and that the bag fits fairly snug against the food items. However, if you were to instead seal the bag leaving it loose and not forcing out the air, then you would perhaps want to use an even higher “cc” rated absorber to compensate for that excess air. All numbers listed herein are approximated. The above numbers are for the minimum recommended size of oxygen absorbers. Feel free to use an even larger sized absorber to ensure continued freshness for longer storage times. 

** NOTE: unlike most foods, white refined sugar crystals are hardly impacted by oxygen.  In so far as sugar will have nearly the same shelf life regardless of the presence or absence of oxygen. Yet, some people still chose to use Oxygen Absorbers inside their Mylar Pro Bag so that insects will not be able to survive inside to feast upon the sugar.  However, please note that the O2 Absorber may cause the sugar to harden and clump together like a brick.  At which point you would need to then smash or break apart the clump to get it back to being in the granule form.
