Raw honey is honey that has been extracted from the comb, and then bottled, etc without HEATING, FILTERING or ADULTERATING. Yes, you can warm honey to 100 degrees (it can get that hot in hives at times), and you can strain it - I strain mine through a pair of womens stockings just prior to going into my bottling tank. The stockings stop all bee parts, large wax particles, propolis, etc from passing through however, it does allow the pollen to pass through. The end result is a clean honey containing all the pollen, amino acids, etc and no damage to the product. Heat above 140 degrees damages honey within a few minutes, and at 160 will pasturize it, which kills everything good. Removal of pollen by filtering takes the protein out of the honey.
To keep honey clear and drastically slow the rate of crystallization on the shelf, the big stores want their honey filtered and pasturized, leaving it as nothing more than sugar, with no healthy benefits. I tell my customers to ask to what temperature the honey was heated, and how it was strained. If the person selling you the honey can't tell you that, then WALK AWAY.. no respectable beekeeper will ever knowingly damage their honey, nor will they tell you its raw when its not. Every day at farmers markets, etc, I come across people selling honey who are NOT beekeepers. They go to the big honey processors and buy honey in bulk, then sell it as raw. I know people in the bulk processing business and they HEAT and FILTER all their honey....
