Temperature Effect to Honey Quality
Honey quality can change of temperature effect, this is because of honey contains itself can broken to high temperature, also vitamin contain can damage by high temperature effect. This is why; honey should be placed in certain condition, safe, cold environment and using glass bottle. The description of honey contain as follows.
Honey is a mixture of many substances. Apart from the carbohydrates which make up the basic components, numerous other substances are included. Among the volatile compounds which are related to honey’s flavor, most are compounds deriving from the original honey source (nectar, honeydew) and some of them arise during processing or storage.
In this work, the effect of heat on the profile of volatiles of pine honey was studied. Pine honey samples were heated to 45 °C, 55 °C, 65 °C, and 75 °C and for 1, 6, 24 and 48 hours. All samples were analyzed using a Purge & Trap - GC – MS system.
The results indicated that nine volatile compounds changed. All these substances were furan derivatives. It was found that the above changes were significant for temperatures higher than 45 °C. Also, the changes were depended on duration of heating. Furfural was the compound that had increased more than other substances. Moreover, the increasing rates of HMF and furfural concentrations were studied. It was concluded that furfural was more sensitive to heating than HMF. So as totally the honey quality will change or degrade and will lessen the function of honey to human body.

that's gotta be the longest way around to say don't heater honey too much or it will loose its afecttiveness thanks though I really wanted to confirm it I suspected as much it seems to make sense
Hello,
I just wanted to ask besides the statements is there any link for a specific survey available. I ask this because not only is very helpful for others to know why but I do not have a serious reason to believe statements alone. My statements goes like that: honey do not loose their properties when heated till 200 degrees Celsius.
Thank you!
OK, I don't know who are you, but I read the same meaning as on Wikipedia about Honey as on below, the recommendation heating just untill 72 Celcius degree, over than this will destroy the original properties and the benefit of honey, you just have the rest substance like sugar:
Pasteurized honey is honey that has been heated in a pasteurization process which requires temperatures of 161 °F (72 °C) or higher. Pasteurization destroys yeast cells. It also liquefies any microcrystals in the honey, which delays the onset of visible crystallization. However, excessive heat exposure also results in product deterioration, as it increases the level of hydroxymethylfurfural (HMF) and reduces enzyme (e.g. diastase) activity. Heat also affects appearance (darkens the natural honey color), taste, and fragrance.
