OK. Honey has no expiration date, and this premise is that the honey must be pure enough. American archaeologists have found a jar of honey more than 3,000 years ago in the pyramids of ancient Egypt.
This jar of honey has not deteriorated to this day, nor has it dried into lumps, and it is still edible. Therefore, honey has no expiration date.

You can drink it, but it has a shelf life as a food.
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 food products, 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.
Efficacy and role of honey.
In addition to glucose and fructose, honey contains various vitamins, minerals, and amino acids. 1 kg of honey contains 2940 calories. Honey is a supersaturated solution of sugar, which crystallizes at low temperatures, and it is glucose that produces crystals, and the part that does not crystallize is mainly fructose.
Efficacy and function of honey: skin care and beauty, antibacterial and anti-inflammatory, promote tissue regeneration, promote digestion, improve immunity, promote longevity, improve sleep, liver protection, anti-fatigue, promote children's growth and development, protect cardiovascular, moisten the lungs and relieve cough, etc.

For natural honey, because it contains a very small amount of water and a high concentration of solution, the osmotic pressure in honey is relatively high, and ordinary cells cannot grow and reproduce in this environment, and honey also contains glucose oxidase that inhibits the growth of bacteria, so natural honey does not have a fixed shelf life, as long as it is stored properly, it can be eaten normally.
Most of the honey we eat daily is formed through secondary processing, and the quality of honey on the market is also uneven. China's "Food Law" requires that all food products have a shelf life, and the shelf life of honey from general honey manufacturers is 2 years, and the honey of farmers is 6 months because it has not been treated with preservatives.
High-quality and unspoiled honey is pale yellow or amber, the solution is thick and translucent, no impurities and no sediment, soft to pick, showing a continuous flow of filaments. Spoiled honey produces sugar-resistant yeasts, which break down sugars in honey into alcohol, carbon dioxide and water, which under certain conditions are oxidized to form acetic acid. Spoiled honey will produce a large number of cloudy bubbles on the surface, and the texture will become sparse accordingly, and if it is packed in a plastic container, it will appear to swell.
However, if the honey is crystallized and layered, dense and granular, there is no need to worry, this situation is generally because a large amount of glucose in the honey is condensed into a solid at low temperature, which will not affect the nutrients and taste of the honey itself, and can be eaten with confidence.
Normalized honey generally has a faint floral aroma, which is not rich or pungent. After deterioration, the smell of alcohol or rancid smell is produced due to the decomposition of the substance, which generally cannot be dissipated for a long time. It is not recommended to continue to eat, otherwise it will affect the quality of honey and cause some harm to the human body.
Honey needs to be stored in a dark, ventilated, dry and cool environment, the temperature is kept at 5-10, and the humidity in the air should not exceed 75%. At the same time, there are certain requirements for the container for the installation of honey. Because honey itself is weakly acidic and prone to chemical reactions after contact with metal objects, it is necessary to use non-metallic containers such as ceramics, glass bottles, non-toxic plastic barrels and other containers to store honey.

Whether honey that has been left out for a long time can be eaten depends on whether it has spoiled or not. Honey is the nectar or secretion of plants collected by bees, which is fully brewed, most of them are sweet but not greasy, rich in a variety of substances, and have a variety of benefits to the body, while honey can no longer be eaten after it has deteriorated.
The shelf life of honey products on the market is generally 18 months or 2 years, but due to the acidic substances and high concentration of sugars in honey, the water content of mature honey is less than 20%. Therefore, if it is well preserved, honey can continue to be consumed beyond its expiration date.
-
If it expires for too long, you can't eat it, because the expired honey has no nutritional value, and eating it may even be harmful to the body.
-
If the time is particularly long, it is best not to eat it, there are a lot of bacteria in it, which may cause cancer and a lot of bad things.
-
I think honey can't be eaten after a long time, because it's not good for people's health at all, and it's not good for people's physical development at all.
-
There is no so-called strict shelf life for real and innocent honey, and it may not be bad for hundreds of years if it is well preserved, and the general merchants set the shelf life of honey at 2 years or 18 months.
-
Pure honey does not spoil and can be left for as long as it wants.
-
It turns out that honey does not spoil and can last for 3,300 years!
-
You can eat it, it is normal for it to have crystals, after all, there are refining and processing ingredients, remember not to remember to add too hot water, or nutrition will be lost.

No, honey also has a shelf life, otherwise the honey sold on the market will not indicate that it has an expiration date, so it is recommended that you throw it away.
Honey has a strong antioxidant capacity, and if it is not in direct contact with the air, it can be stored for a long time without spoilage. Therefore, it is very important to store the honey jar, first of all, the jar should not be able to react chemically with the honey, and secondly, the jar should be airtight. >>>More
Fresh blueberries need to be stored at a temperature of less than 10 percent, even during transportation. However, the fruit must go through a pre-cooling process to remove the heat from the field to effectively prevent rotting. The main methods of pre-cooling are vacuum cooling, cold water cooling, and cold air cooling. >>>More
