The natural crystallization of honey is a purely physical phenomenon and is not a chemical property. The speed of honey crystallization is closely related to the number of glucose crystal nuclei, temperature, water content and nectar source flower species. Under normal conditions, the higher the content of glucose in honey, the greater the number of crystal nuclei, and the faster the crystallization speed, because the crystallization of honey is essentially a phenomenon and process in which glucose is precipitated and separated from honey.
From the point of view of molecular theory, the glucose molecule in honey is originally moving in an orderly manner, but at a certain temperature, when the glucose in the honey exceeds its solubility and becomes a supersaturated solution, a part of the glucose molecule begins to move and arrange regularly in the honey, forming a tiny crystal nucleus and becoming a crystalline center, and more glucose molecules are regularly arranged on all sides of it, gradually forming larger crystals, which are separated from the honey, and the crystals are quickly produced. This is the whole process of honey crystallization. Therefore, crystallized honey not only has no effect on its nutritional composition and application value, but also makes its properties more stable, and the crystals precipitated are glucose, which is very soft rather than white sugar (honey mixed with sugar is very hard when poked with chopsticks after precipitation). Crystallized honey is best eaten directly, or it can be dissolved by heating it in hot water at about 60 degrees.
Of course, a few honey such as acacia flowers and jujube flowers have a high fructose content, so they rarely crystallize. In addition, honey that has been concentrated at ultra-high temperatures is generally not easy to crystallize because it destroys the crystal core, but at the same time, it also destroys the nutrients, making it very valuable. Fake honey generally has no crystallization properties.

Another form of honey – crystalline. The relationship between liquid honey and crystalline honey is similar to the relationship between water and ice. It is mainly through crystallization to precipitate glucose from solution.
Due to the influence of temperature, humidity and time, the two behaviors will switch to each other. The natural crystallization of honey is purely a physical phenomenon and is not a chemical change, so it has no effect on its nutritional content and application value.
Honey is a supersaturated solution of glucose, fructose. Due to the fact that glucose is easy to crystallize, some honeys (such as wild osmanthus nectar, rape honey, linden honey, etc.) are easily precipitated in oily, fine-grained or coarse-grained crystals when honey is placed in an environment of 13 to 14 degrees Celsius. If the honey has a low concentration and high water content, stratification will be formed, and the crystalline part will sink to the bottom, and the other thin sugar solution will float on the upper layer.
However, there are also cases where the upper layer is a solid crystal and the bottom layer is liquid. Crystallized honey is heated (40 to 50 degrees Celsius) and then melts into liquid honey.
Different honeys have different crystallization speeds and grain sizes due to differences in chemical composition. Generally, honey with high glucose content and sucrose (such as rape honey, cotton honey, sunflower honey, etc.) is easy to crystallize. Honey with high fructose content (such as acacia honey, jujube nectar, etc.) is not easy to crystallize.
When a non-crystallizing honey is mixed with an easy-to-crystallize honey, the crystallization rate of the honey can be accelerated. For example, the flowering time of canola and milk vetch is similar, so milk vetch honey often contains a small amount of rape honey, which is why milk vetch honey forms partial crystals.

Why does honey appear a layer of crystals after it has been left for a long time?
-
Honey crystallizes after a long time, honey crystallization is glucose around the crystal nucleus to form particles, and around the particles is wrapped with a layer of fructose, sucrose or dextrin film, gradually coalescing and expanding, and the honey in the whole container partially or completely forms a loose solid, that is, honey crystallization. Therefore, honey crystallization is a normal phenomenon that has no effect on its nutritional content and application value, nor does it affect consumption.

First, heat the honey in a small pot or basin of clear tung source water. Do not overflow the honey bottle with water, and turn off the heat when the temperature reaches about 80 degrees. Hold the honey bottle and stir it back and forth in hot water to slowly melt the crystallized honey before pouring it out.
If it is winter, you can put the container on the heating pipe and wait for the honey to melt slowly.
In the summer, when the temperature is high at noon, the unsealed honey bottle can also be melted and crystallized by placing it in the courtyard or on the balcony.
Honey crystallization is a natural phenomenon of honey. In essence, it is a local phenomenon and process in which glucose is separated from honey.

Pro, honey crystallization is a natural phenomenon, which does not affect the nutrition and taste of honey, but some people may find the taste poor. Here's how to deal with honey crystals:1
Hot water method. Put the crystallized honey into hot water, control the temperature at about 40, and stir well after the honey is softened. 2.
Air-drying. Pour the crystallized honey into a container, cover it with a lid and let it air dry in the sun for some time. This allows the honey to gradually return to its liquid state.
3.Microwave oven method. Pour the crystallized honey into a special baking tray in the microwave, microwave for 1-2 minutes, control the temperature at about 40, and stir well after softening.
It should be noted that when processing the crystallization of honey shirts, the temperature needs to be hidden in the closed belt, and the temperature should not be overheated, otherwise the quality and taste of the honey will be affected. In addition, it is not recommended to use high-temperature treatment methods such as heating to the boiling point, which will destroy the nutrients in the honey.

Honey is easy to crystallize in the second half of the day at low temperatures.
Honey crystallization is carried out under certain temperature conditions, most honey is the easiest to crystallize at 13-14 hours, if it is lower than this temperature, the viscosity of honey will be greatly improved, and the speed of honey crystallization will be slowed down. The crystallization of honey is a natural physical phenomenon, which can be fast and slow, and cannot be artificially interfered with.
Acacia honey is not easy to crystallize, the crystallization speed is very slow, and there will crystallize when the temperature is particularly low, so honey that is not easy to crystallize does not mean that it does not crystallize. The climate and temperature of the north of China are very different, and the acacia honey in the coastal area of Guangdong does not crystallize, while the low temperature in the northern region is long in winter, and the acacia honey will also crystallize.
Rape honey is easy to crystallize, it is observed that rape honey begins to crystallize after a week, so honey crystallization also depends on the type of honey, different kinds of bee preparation honey crystallization speed is different, sometimes even the same kind of honey in different stages, different conditions The crystallization speed will be different, some crystallize more, some crystallize less.

<> honey crystallizes due to various factors such as temperature and water content, and putting it in the refrigerator is only one of the influencing factors. The sugars in honey are mainly derived from grape sugar and fructose, which crystallize when the content of these sugars exceeds the solubility limit. The crystallization time of honey varies depending on the variety and production process.
In general, honey stored in the refrigerator does not crystallize easily, because the low temperature environment slows down the rate of crystallization of sugars in honey. However, if the honey itself contains high sugar content and has no honey stains, or if it is stored in the freezer, it may speed up the process of dispersing the honey. In addition, honey should also be stored in ordinary times to avoid temperature and humidity fluctuations, so as not to affect its taste and quality.
If the honey has become solid due to crystallization, it can be heated in warm water until the honey begins to thin, and after stirring well, it can return to its original state. It should be noted that although honey can be heated back to thinning, heating at too high a temperature will affect the nutritional value and taste of honey, so it is recommended to heat it at a temperature below 50.

Under normal circumstances, honey crystallizes after five or six hours in the refrigerator.

Fresh honey separated from the hive is mostly a viscous, transparent or translucent gelatinous liquid. When stored at room temperature, some honey will gradually become cloudy and then coagulate into white crystals, which is the natural crystallization of honey. Honey crystallization is a physical phenomenon that usually does not affect its intrinsic quality!
There are many factors affecting the crystallization of honey, and the speed of crystallization is also closely related to the number of glucose crystal nuclei, the temperature, the amount of water content and the external temperature, among which the composition of nectar and the change of temperature have the greatest impact on it.
Any honey that has just been separated may look clear and transparent on the outside, but if you look at it under a microscope, you can see that there are many small glucose crystals that are constantly moving. The glucose molecules in honey surround the crystal nucleus, like a snowball, constantly moving and gradually getting larger, and finally become a larger crystal, which precipitates at the bottom of the volume. Generally speaking, the higher the glucose content of honey, the more crystals and the faster the crystallization.
It can be seen from this that crystalline honey, in fact, is the crystalline glucose precipitated from honey, which is still a delicious natural sugar flavor, and it is by no means spoiled and deteriorated, so you can enjoy it with confidence.
13 14 is the temperature at which honey is most likely to crystallize. Therefore, many people are accustomed to storing honey in the refrigerator, which is not a good storage method. Because when the temperature gradually drops to about 5 before refrigeration, it has passed the stage of 13 and 14, which can easily promote the crystallization of honey.
If you do not understand the cause of this, but mistakenly think that it has deteriorated and deteriorated, then it is a great wrong.
Of course, not all pure honey will crystallize, for example, acacia honey will not crystallize, and the form of honey is different in different seasons. Duck's foot wood honey is the king of winter honey and is very easy to crystallize. These two kinds of honey are selling well in the "little bee that sells honey" with a Tao name, I just bought it yesterday, acacia honey and thick quality are very good, lips and teeth are fragrant.
