Pasteurizing honey is a very different thing than pasteurizing milk or other dairy products, and it’s done for very different reasons. Because of its low moisture content and high acidity, bacteria and other harmful organisms cannot live or reproduce in honey, so pasteurization is not done for that purpose.nother side benefit of pasteurizing honey is that it will slow down the granulation process. Pasteurized honey will last longer in its liquid state than unpasteurized honey, which makes for a more appealing-looking product for both retailers and consumers.
