Dennis and group,

I wondered if any of you have taken the trouble to check what the
average particle size is for the powdered sugar available in each of
your own locations or better said countries?
The reason why I take this up is the possible use of powdered sugar
in the fight against Varroa mites, as for instance taken up here on
BEE-L by Dennis Murrel and also on other lists and seen in the
different research articles.
The sugar particle size as I understand seems of importance in this
application.
Since we are beekeepers from different countries, I wondered if
there perhaps would be industry standards that set the minimum and
maximum particle size that sugar producers have to adhere to? Also,
going by the names under which the finer sugars are marketed, it almost
seems as if each country has several qualities of this sugar. Perhaps I'm
wrong and do all the different names still apply to just one kind of fine
sugar...but that's just what I would like to find out.
This weekend I will buy some fresh Swedish powdered sugars from
different manufacturers and measure some of it under the microscope
to see if it equals the size of 20-40 micron that for instance Kamran
Fakhimzadeh from Finland in some of his research referred to as
"confectioner sugar".
