After opening, honey can be stored for up to three months as long as there is no water mixed with it. However, if there is water, it will become moldy and spoiled about two weeks after entering it.
How honey is selected:
In appearance, a good honey should be a moist, gelatinous liquid that has the characteristic luster of honey, but is not as translucent and clear as water. Therefore, do not choose honey that is particularly transparent or dull in color.
Good honey can be smelled. Monofloral nectar will have the same intense aroma as the nectar source plant, such as locust nectar.
There is the fragrance of acacia flowers, and osmanthus nectar has the sweet fragrance of osmanthus flowers.
In general, the thicker the honey, the better. This is because the viscosity of honey is related to its moisture content, and the national standard stipulates that the moisture content is less than 20% as a first-class product. When picking honey in the supermarket, you can turn the bottle upside down and make it thicker and slower it trickles.
Due to its viscous texture, honey has the characteristic of being constantly brushed.
After buying the honey home, drop a drop, the good honey is very long drawn, and the upper end will spring back quickly after the flow is broken. If it's fake honey or low-quality honey, it won't bounce back quickly.
Honey crystallization. It is a concern for many consumers. Many people wonder if crystallized honey is of poor quality. Honey crystallization is a very normal phenomenon, and it has nothing to do with the quality, but with the honey species and storage conditions. Generally honey at 13 degrees Celsius.
The following crystals, and rape honey, linden honey.
At 13-14 degrees Celsius it will crystallize, acacia honey.
It is less easy to crystallize. In fact, crystallized honey does not affect consumption.

How long can honey be left after opening mainly depends on the quality of the honey.
1. First of all, we must see whether your honey has fermented and deteriorated. If it is fermented, it smells like alcohol, and it has deteriorated, and even if it is not opened, it cannot be eaten and must be thrown away. If the above deterioration does not occur, it is edible.
2. Honey has no shelf life, it is for high-quality honey, not for low-quality honey, so the quality of the honey you buy determines how long your honey has a shelf life.
3. The concentrated honey has been processed, and most of the honey can be stored for three or five years, even if the shelf life is marked on the bottle for 2 years, as long as there is no obvious foam and wine flavor (that is, fermentation), it can be eaten.
4. Honey should be sealed and preserved, otherwise, it is easy to get damp, easy to absorb flavor, and it is easy to make a bottle of good honey deteriorate and deteriorate. As long as you open the seal, you still screw the mouth, there is no problem, as long as it is not open.
Preservation of honey.
Honey can be sealed and stored at room temperature, and the honey will be placed at room temperature for a long time, without mildew or qualitative change, the main reason is that honey has a strong antibacterial effect on various bacteria. Honey contains antioxidants, but also because it is acidic and has a high sugar content, it maintains a high penetration power, and microorganisms cannot survive in this environment.
Experts point out that honey can be kept in the refrigerator, but keeping it in the refrigerator will cause it to crystallize and precipitate glucose. This change does not affect the safety of honey, nor does it affect its nutritional value, but it only affects the uniformity of the taste.
In addition, honey is a weakly acidic substance, and it is best to use glass or ceramic utensils to store pure honey, not metal utensils such as iron and lead, so as not to contaminate the honey with free heavy metals. Honey stored in non-toxic plastic bottles should not be too long.
Honey packed in containers is best sealed with a lid and protected from contact with moist air to avoid fermentation. It should be kept in a clean, cool and ventilated place, and it is best to keep the honey in the refrigerator, taking care to avoid contamination.

Honey is a liquid with a weak acidity, so it is best to use non-metallic containers such as glass bottles, barrels, and clay jars to hold honey. And store at low temperature to reduce discoloration and taste.
Honey should be stored at a low temperature and away from light. Since honey is a weakly acidic liquid, it can react chemically with metals, and chemical reactions will occur when it comes into contact with metals such as lead, zinc, and iron during storage. Therefore, non-metallic containers such as ceramics, glass bottles, non-toxic plastic drums and other containers should be used to store honey.
During the storage process, honey should also be protected from cross-flavoring, wetness, fermentation, pollution, etc. In order to avoid odor and pollution, it should not be stored with odorous items (such as gasoline, alcohol, garlic, etc.), corrosive items (such as fertilizers, pesticides, lime, alkali, nitrate, etc.) or unhygienic items (such as waste products, livestock products, etc.).
The shelf life of honey is currently 18 months for bottled honey. However, bees with high cap maturity concentrations can also last for many years. However, it is better to eat fresh honey, because fresh honey generally has a better color, aroma and taste.
Tip: Use a clean glass bottle and store it in a cool place in a sealed and cool place in the ratio of 1000 grams of honey to two small slices of ginger. This method can make the honey not taste for a long time.
Scientific research and practice have proven that honey has strong antibacterial ability and is the only food in the world that does not spoil. In 1913, American archaeologists found a jar of honey in the ancient tombs of the pyramids in Egypt, which was identified as having lasted for more than 3,300 years, but it has not deteriorated at all and is still edible. It can be seen that truly mature honey is completely edible after a long time, and there is no strict shelf life, but as a food market, according to the "Food Law", the shelf life is required to be marked on the food commodity, so honey manufacturers generally set the shelf life of honey at 2 years.
However, it must be pointed out that if it is not mature honey or inferior products such as water, these honeys will ferment and bubble, become sour, and become inedible after a long time. Of course, if the fermentation is not serious, it can still be eaten after heating in a water bath for half an hour at about 60.
In short, no matter what kind of honey it is, and no matter how long it has been preserved, as long as it has not deteriorated, it is edible and will not be harmful to the body. It's just that long-aged honey has a slightly worse nutritional value than fresh honey.

Honey is a natural nourishing food, which is loved by consumers because of its rich nutrition and sweet taste. As a result, many people always have a bottle of honey at home, but they often forget to eat it due to busy work, business trips, etc. So how long does honey last after opening?
Let's find out about the field bees.
Natural mature honey is a natural sterilant that contains a high concentration of sugars and acids, and has strong antibacterial properties that can inhibit the growth of bacteria. Generally, as long as you pay attention to the storage method after opening, it is not easy to deteriorate and can be stored for a long time.
However, for those honey with high water content, even if it is well preserved after opening, it is easy to deteriorate. This is mainly because the water content of honey exceeds 21%, which creates favorable conditions for yeast to grow and reproduce, and yeast will break down the sugars in honey, causing fermentation and deterioration.
Therefore, when you buy honey, you must choose natural mature honey, which has less water content and is not easy to ferment and deteriorate. However, it is also necessary to pay attention to the preservation method, because the water absorption of honey is relatively strong, if the honey is placed in the air with high humidity, the honey will absorb the moisture in the air, causing fermentation and deterioration, so everyone must seal and store the honey after taking it. In addition, honey also has a strong odor absorption, so it is best not to store it with food with volatile odor when storing, so as not to make it difficult to eat in the case of cross-smell.
It is best to store honey in a cool, dry, ventilated place without direct sunlight.

Unopened honey can be left out for two years, and honey can be left open for one year.
After a large number of studies, it has been proved that honey has relatively good antibacterial ability and is generally not prone to spoilage. However, most of the honey on the market today is not pure honey because it has other additives added, so it also has a shelf life. After the expiration date, honey generally becomes sour, ferments and bubbles, in which case the honey cannot be consumed.
-
Honey can generally be stored for about 2 years, depending on the storage environment. Honey should be sealed and stored in a low, ventilated and clean place, and protected from light, because light may destroy the vitamin B complex in honey, resulting in the loss of nutrients.
The container where the honey is stored must be tightly covered, otherwise the honey will absorb moisture in the air and easily cause fermentation and deterioration.
If you buy honey at a supermarket, etc., the storage time should refer to the expiration date on the package, and it is not recommended to consume it after the expiration date.
It is normal for honey to turn white at the bottom of the refrigerator because honey is a supersaturated solution of sugar, which crystallizes at low temperatures.

Generally, it is about 2 years. Honey has two different physical states at room temperature and pressure, namely liquid and crystalline (regardless of whether the honey is stored in the nest or separated from the nest). Liquid honey is a liquid that separates honey from the hive and remains transparent or translucent at all times.
However, most varieties of honey gradually form a crystalline state after a period of time, especially when the temperature is low, so that honey is called crystalline honey.
Crystallization is due to the fact that the glucose contained in honey has the property of easy crystallization, so crystallized honey does not reduce its nutritional value and natural food nature, it is a purely physical phenomenon.
Precautions. Natural honey containing active enzymes should not be heated above 60 degrees Celsius, otherwise the active enzymes will denature and inactivate at high temperatures, destroying the nutrients in it. Honey has a sweet taste when brewed in warm or cold water, and a sour taste when brewed at higher temperatures.

Myth: Honey is a food that can be preserved forever. This is because honey itself has a low water content (less than 20%) and a high osmotic pressure, and when bacteria and honey meet, the high osmotic environment will cause the bacteria's cell fluid to seep out of the cell membrane, resulting in bacterial dehydration and death.
Truth: For honey, a food that is not easy to grow microorganisms, as long as it is "mature honey" and the storage environment is closed and cool, it can be stored indefinitely. However, from a practical point of view, the need to open the lid when eating honey and the high storage temperature will lead to the production of bacteria, so it is difficult to preserve honey for a long time.

Honey is usually stored in a cool place, if possible, it is best to store it in the refrigerator, and for how long? This is related to the quality of honey, the Baumé degree of 37-38 degrees of honey stored in a cool place can be kept for one year without deterioration, 39 degrees can be kept for two years, 40 degrees can be kept for more than three years, and 43 degrees can be kept for several years without deterioration. Generally, naturally capped mature honey is at least more than one year old, honey has a strong antibacterial ability, and is the only food in the world that will not spoil.
Truly ripe natural honey is completely edible after a long period of time, and there is no strict shelf life. However, as a food product, according to the Food Law, the shelf life is required to be indicated on the food product, so honey manufacturers generally set the shelf life of honey at 2 years. The shelf life is set at two years, not only because food requires this, but also for another important reason, which is that modern honey is difficult to find naturally ripened honey.

This depends on what kind of honey you want to store, if it is unprocessed raw honey can be stored for three years, it is no problem, if it is the kind of blended honey in the supermarket, then you have to go according to the expiration date.

Honey can be stored for 2 years after opening. Honey has a high concentration and osmotic pressure, and the cells that enter it will be severely dehydrated and die, so it is not easy to deteriorate. Honey should be preserved in non-metallic containers such as ceramics, glass bottles, non-toxic plastic barrels, and then placed in a cool, dry, ventilated place.

Everyone's impression of honey is that it has been preserved for a long time, and it is true. Most of the bottled honey on the market has a shelf life of 18 months or 2 years, in fact, honey is a special food, which contains acidic substances and high concentration of sugars, and the water content of pure mature honey is generally less than 20%, so honey has a strong bactericidal ability. Generally, honey is kept well beyond the shelf life on the packaging, when it is well preserved. >>>More
No, honey only moistens the lungs. If you want to suppress cough and reduce phlegm, you need to add pears and fritillary (available in Chinese medicine stores), steam them through water, eat pears and fritillary to drink soup.
Yes, God. However, ripe honey has a faint floral aroma on the palate. Naturally ripened honey, that is, honey brewed mature honey, not only has a sweet taste, but also a faint floral aroma, and the longer it is stored, the less fragrant it becomes (except for a few honey species). >>>More
