Does Filtering or Straining Honey Remove Pollen From Honey?

Honey bees bounce from flower  to flower, pulling nectar and collecting pollen from each flower. Day in and day out, foraging for these ingredients, bringing loads back to the hive. Either on purpose or accidentally, pollen ends up in the stored nectar before it turns into honey.

While harvesting the finished honey, beekeepers will remove wax coverings from each cell and remove the honey. Typically straining the honey before placing it into bottles.

Now what happens to the pollen that was in the honey?

The vast majority of pollen collected by the bees is not mixed with the honey. Bees typically store pollen separate from honey, but some pollen will be mixed with the honey. Beekeepers typically strain bits of comb and bees from honey for appearance sake. Most beekeepers believe using very small filters will exclude the pollen and separate it from the honey. I believed it for years until I heard an expert, a palynologist, speak on the matter. Dr. Richard Carroll from The University of Alabama, shared some interesting information about pollen. 

The average pollen grain is 25 microns wide, much smaller than the smallest filter a non-commercial beekeeper will have.  Filters designed for straining honey for hobby beekeepers come in three sizes, 200 microns, 400 microns and 600 microns. These numbers represent the size of the tiny holes in each filter.

Some of the largest pollen granules only measure 100 microns wide, half the size of the smallest hobbyist filter. So rest assured, if you are worrying about buying honey with all the pollen strained out or straining out the pollen out of your own honey, you can put that behind you. A hobbyist beekeeper would have to really go out of their way to get rid of their pollen.

Happy Beekeeping
