Honey does change color over time. Because pure honey is alive and not immutable. As the storage time increases, the pollen in the honey will gradually settle, which will deepen the color of the honey.
This is a natural phenomenon of honey, like buckwheat honey, which gives people the illusion of blackness when left for a long time.
However, not all aged honey will turn black in color, it is related to the color of the honey itself and the color of the pollen. Light-colored honey like water white honey will not appear black for a long time. However, it is true that the color of honey will deepen over time.
One thing to remind everyone is that honey is a healthy food, and all foods have a shelf life, and the shelf life of honey in the market is generally 18 months or 2 years. This period is the best consumption period for honey.

The honey turned black all of a sudden, can you still eat this? What causes this? We all know that honey has a lot of nutrients, which is very popular with the public and is also a must-have for every family.
Therefore, it is easy to accidentally buy too much, and we always ignore the little things around us, so pay attention to it. Today, let's take you to understand why honey turns black.
Some friends bought honey and found that after a while, the color of the honey turned dark. People are very worried, and I don't know if the blackened honey can continue to be eaten. So what is the reason for the darkening of honey?
1. The reason why the color of honey turns black.
1. The influence of flower-derived plants. Some honey from nectar plants is inherently darker, such as buckwheat honey. Buckwheat honey is dark amber in color and looks a little black.
There is also the fact that some honeys are brewed by bees that collect more nectar from other species. Miscellaneous nectar affects the color of the honey, resulting in a dark color of the honey.
2. Leaving it for too long. Some honey is not eaten often, and if it is left for too long, it will produce a lot of insect enzyme metabolites in the honey, making the honey darker or darker. Such honey should not be consumed any longer, and it may have a tendency to spoil.
3. It may be that the honey is contaminated. For example, some honey manufacturers do not pay attention to the filling conditions, some production and processing equipment is not regularly maintained, and the metal surface of the production equipment is corroded. Honey itself is acidic, and contact with metals produces oxidation, which contaminates the honey.
If the honey is kept in a metal container, the honey will also react with the metal for a long time, causing the honey to deteriorate.
Therefore, there are many factors that affect the darkening of honey, some of which are normal for dark color. Some of them are caused by the deterioration of the honey for too long, or the honey is contaminated. Field bees remind that honey should be sealed in glassware or food-grade plastic products in the dark.
2. Recommendations. 1. Honey generally cannot pass through high temperatures, which will destroy the ingredients in it.
2. Storage The reason why honey turns black is mainly caused by your container, if you use glass or ceramic containers to store it, it will be fine for ten years (but it must be pure honey).
3. Generally, the shelf life of honey is between 18 months and 2 years, and there is no problem with the color of honey or sugar formation during this period.
4. Store it in the refrigerator in summer, and usually put it in a cool place. If you deposit improperly, it may deteriorate.
Honey has the effect of supplementing nutrients, and makes it more moisturizing, especially in winter, when applied to the skin, it can make it brighter, and it is relatively simple and effective, it can make the pores of the skin smaller, and it can also inhibit the appearance of dark spots.
Honey should be matched using scientific methods, not randomly, otherwise it will destroy the original nutritional value of honey. To know how to preserve. It can be preserved well without destroying the nutritional value of honey, and will not make honey often easy to spoil, or even spoiled.
Therefore, honey should be bought in moderation, and it should not be bought when you see it, even if it is a necessity of life.

The darkening of honey is usually due to prolonged exposure to sunlight or air, the effects of light and oxidation, which cause some of its components to change. If the honey that has turned black and has no signs of deterioration, such as peculiar smell and mold, it is generally edible. However, it is recommended to buy high-quality honey produced by regular manufacturers, such as Ma Erge Qinling soil honey, honey Xiaowutu honey and Zhenfeng Baicao soil honey, these honeys come from natural honey sources, and after scientific production technology, the quality and purity of honey are guaranteed, and it is more assured and healthy to eat.

Honey blackening is not edible, and it will only turn black when the honey has deteriorated.
The hypertonic environment of honey makes it difficult for spoilage microorganisms to survive, but there is a group of microorganisms called "osmophilic yeast" that can survive in honey tenaciously. If the purchased honey is opened and not sealed when it is stored, it will gradually absorb moisture from the air over time, and the honey may deteriorate.
Expired honey may deteriorate due to the fermentation of osmophilic yeast, but such honey usually only produces a slight sour taste and wine taste, which does not affect the safety of eating, and it is not harmful to eat, but it will affect the taste.

Whether the honey can be eaten after it turns black depends on the specific situation. Some honey (such as buckwheat honey and black honey) itself is black, and the blackening belongs to the special key positive lead of this type of honey, so it does not affect the consumption. If the honey is left for too long, causing the honey to become clear and black, it is recommended not to eat it again.
Honey spoils and will have an alcoholic or sour taste, or many gray bubbles on the surface. Depending on these conditions, it can be checked to see if the blackened honey has gone bad.
In addition, using a metal container to contain honey may cause the honey to oxidize and turn black. If this is the case, it is not recommended to continue consuming it.

No. Honey contains a lot of nutrients and sugars and can go bad easily. If the upper part turns black, it is due to the growth of microorganisms such as bacteria. If a person eats it, it may cause gastrointestinal discomfort or cause food poisoning, which can cause harm to the body. <
