By Alison Rohde; Updated April 30, Viscosity and surface tension are two physical characteristics of a liquid. Viscosity is the measure of how resistant to flow a liquid is, while surface tension is defined as how resistant the surface of a liquid is to penetration. Both viscosity and surface tension are affected by changes in temperature.
Heating and Freezing Honey Heating Honey: In the previous post we looked at why honey crystallizes. Since it's a natural for the sugars in honey to crystallize over time, what's the best method to re-liquefy it? The answer is to use heat, but the question is how much?
Too much heat will destroy the nutritional elements of honey. Many commercial beekeepers invest in heated honey storage tanks. With the constant heat the honey never gets a chance to form crystals.
These tanks are always kept around degrees F. More on this later when I learn more about them… With our small time operation with no heated tank not yet at least we keep all our honey in glass jars. Using glass makes it easier to heat the honey up.
In previous years we kept our honey in food grade plastic containers but then it crystallized in those containers and then had to be scooped out into jars and then heated to liquefy.
So now we're skipping the plastic entirely. All family members and even a few friends save and wash all their glass pickle, relish, jam jars, etc. We don't put all our honey in "for sale" jars until we need them.
That way we don't have to buy boxes and boxes of for sale jars all at once. When ready, we heat the jars to liquefy the honey and then pour into the for sale jars as needed and label them.
We still use them but the jars are used first. This is the marketing manager's Dad's job. He and Mom boil water in their pressure cooker. Then they turn off the heat and set the honey jars inside the hot water. The pressure cooker has a wire base which keeps the jars from sitting directly on the metal bottom.
They leave the jars for a couple hours and the heat works to slowly melt the crystals.
Cooking at this heat destroys yeast cells, reduces enzymes, darkens the colour and changes the taste and smell of the honey. Honey will not freeze solid. Instead, as the temperatures become colder it becomes thicker think of the saying like Molasses in January….
While appearing or even feeling solid, it will continue to flow at very slow rates. My preference is to scoop the crystallized honey straight from the jar and into my hot tea.
In my opinion that's the best way to melt it. Many thanks to those experts who contribute to Wikepedia where this info came from Posted by.Oct 12, · Any heating of honey will reduce its aroma and flavour and in time darken the honey.
Heating honey above 50°C (°F) will damage its food value. This is because the diastase or enzymes put into the honey by the gathering and storing bees is destroyed within a few hours at 50°C.
I originally wrote this article in , since then I have continued to keep bees and rear some queens every year. I have tried most of the other popular methods, but this one is still my favorite for the size of my apiary and my needs.

Decrease viscosity and increase density. Commentary. In general, liquids tend to get “thinner” when their temperature increases. For example, honey and oil tend to flow better at higher temperatures. Hi Janet, Yes, it is. It was not heated for filtration reasons, or pasteurized to last longer in the liquid form on the shelf.
The only process that is applied to medical grade manuka honey is gamma-radiation – but this is a process that does not influences its medical value or nutritional components in any way. Yet this is done for medical grade honey only.
Dear Dr. Russell, I have sinusitis or allergic rhinitis and its been with me for probably more than 6 month now. Should I start using the saline rinses including the Manuka Honey in the saline recipe?
