Thank you for the messages .... Chris - one sample was honey from my own hives. The other was a sample from a dealer but said to be from hives just south of my own. I want to do this test since Chinese honey is now a severe threat here (Thailand). It is very cheap (apparently 60% of local production cost) and generally locally impossible to detect. So I was thinking to compare pollen in honey and see what could be learned. My adventure is to see what can be done. If it works then I will share the methodology with the bee farmers to that they can watch out for questionable purchases when they trade honey. Gavin - thank you for clearly setting out the steps to follow. I can cope with all of that except step #5 which I suspect will become a whole lot clearer when I am in the lab. This looks like being the method to follow it even gives an alternative approach where a centrifuge is not available. The next challenge will of course being to track down a pollen database :) *********************************************** The BEE-L mailing list is powered by L-Soft's renowned LISTSERV(R) list management software.
